Domain Authority / Page Authority tool.
In the eyes of Google not all websites are equal. Some sites get tons of search traffic from Google each day (think of Wikipedia, Amazon, IMDB…), while others are struggling to show up in the SERPs (Search Engine Result pages). There are two major factors influencing the performance / rankings of your website in search:
- Authority – The authority of a website is based on the number of external backlinks, the quality and relevance of these links.
- Content – Great content is key, but needs authority to really excel. If you’d like to know more about content optimization I would suggest checking out the content tools available in this section.
The Website Authority Checker helps you to quickly check the authority of a website to give you a very strong indication how well a website can perform in Google.
The available metrics measured by this tool:
- Moz Domain Authority (DA) – The calculated authority for the complete website / domain, on a 1 – 100 scale.
- Moz Page Authority (PA) – The calculated authority for a specific page, on a 1 – 100 scale.
- Backlinks / external links pointing to a specific URL or domain.
- Website age and URL Age (estimation)
- Social Media score – The total share count from: Facebook and Pinterest
- Google PageRank – The calculated authority on a 1 – 10 scale.
Google PageRank is no longer supported, because Google announced they won’t update this metric any more. Read more about PageRank.
How and when to use this tool?
There are multiple situations where the Website Authority Checker is the tool to use, to get the data a insights you need.
- To check the current authority of your website and or specific pages you’re building links for.
- To research the SEO strength of an competitor in the organic search results.
- To know the value of new links pointing to your website.
- To examine new linkbuilding opportunities.
What is Domain authority?
Domain authority is a metric, developed by SEO, to predict the ability of a website / domain to rank in search engines. Domain authority uses a 0 to 100 logarithmic scale. A high Domain authority score means your complete website / all the pages on your domain have the potential to rank well in search engine results.
What is a good domain authority score?
Ok, this is a question many people ask and there is no magic number here. It all depends, if you focus on a nice market, you might be able to compete with a 20 DA Score. But when you’re Competing with big brands and highly competitive keywords a DA 50 Score might not even be enough. To answer this question, list your organic search competitors. Add them to the bulk Domain and Page Authority Checker (you can check up to 10 results at a time) and scroll down to the bottom where you’ll find the average DA an PA for your query. This number will give you a good indication how you stack up to your competitors.
How to improve your Domain Authority?
Because Domain authority is calculated based on 40+ link based metrics by MOZ, you should focus on getting relevant quality backlinks from high authority domains. This is easier said than done, so to get you on your way I’ve developed the Free Link Building Tool that will help you to identify: Guest post, Resource listings and review link building opportunities.
Domain age vs Website age
This tool calculates Website age because it’s a better and more relevant SEO factor to measure compared to domain age. Especially when you compare Domain and Page Authority, website age shows you how a domain has developed over time. A Website age of 6.4 years means a website is 6 years and 4 months old.
- Domain age – the number of years since a domain has been registered.
- Website age – the first time since a website appeared on-line
Checkout this article by Ann Smarty on the subject “Domain age vs Website age”: http://www.searchenginejournal.com/domain-age-how-important-is-it-for-seo/7296/ In this video, Matt Cutts explains the difference and importance of Domain age (no value) and Website Age.

Hi! I transferred my domain name in January and according to Google, it shouldn’t have impacted my DA because I filled out the Change of Address form on Google. A month ago, my DA was displaying 28; now it displays 18. Is the drastic change due to the age of my domain name? Thank you!
Thanks for sharing this great tool.
Update:
My blog lizzumsliveslife.com is just over one year old – I know because I recently got the renewal through earlier this month. WHOIS also says my domain was reg’d 03/17 but DA checker says my site/domains only 1 month old. I know age can affect DA?
Hi Liz,
This tool checks your website age based on data made available by the Wayback Machine: https://web.archive.org/web/*/https://lizzumsliveslife.com/ and this is the first date they could find.
(The more popular your website.. the more data they will have available)
And age is indeed a metric used by MOZ to calculate Domain Authority, but it’s not the most important factor. Backlinks and their quality / relevancy are the backbone of the algorithm to score your domain (DA).
So to improve your Domain Authority I would advise you to focus on that area.
Hope this helps!
Admin,
I entered the full webpage address but do see that it returns website age as 6.11 years. The website i am checking for is only 3 months old.
Thanks
Hi,
That´s correct. If you click one the age of the website you get referred to the archive.org where you can see they made a screenshot of your website back in February 2011.
I really enjoy using this tool. I love that it’s free and open to public. Thanks guys. Keep it up.
Update:
Let me know what you think about the new results..
Cheers,
Why is my website age N/A?
It isn’t a year old, is that why?
Hi Sander,
To return website age, I use the archive.org / Wayback Machine API. They crawl the internet and after they have indexed your website they will capture your content and add you to their archive. Because they don’t have the crawl capacity like Google or Bing, it takes them a bit longer to get all sites indexed.
Which is probably the reason why the tool isn’t able to return website age for your domain.
Guys, can anyone tell me why the domain authority score changes when searching http:// exampledomain.com vs https:// exampledomain.com?
Hi Sandra,
Just did a check for your domain and a get exactly the same DA score for your site with http or https, so this might have been a temporary issue
How do i improve DA, PA and PR for my website? Looks like it takes some time to build up links.
Hi Sam,
Focus on relevant quality backlinks and your MOZ DA & PA score will improve over time.
(I’ll try to find the time and write some “How to” blogs about: Link building, backlinks and improving your Domain authority… Because the same questions keep popping up ;-).
Speaking of internal linking, I use a plugin to interlink and currently I have it limited to 15 links per page. Does it matter if I remove this limit?
How much of internal linking (is there a percent) is good?
Now, when you stay internal linking, do you recommend using a plugin like this or do you only suggest manual linking?
I look forward to your response to this.
Hi Alena,
Creating internal links is definitely an effective SEO practice.
Using a plugin can be a good way to control and automate this process. You mention working with a 15 links per page limit. In addition I would run a related post plugin to create relations between multiple posts and keyword themes.
Hello, can I see the age of a website, when tool returns N/A ?
Hi Alexx,
If the Way back machine / Internet archive isn’t able to return data for a specific website it is pretty hard to determine the website age but you can have a look at domain age to get an indication.
(notice the difference)
Cheers,
Hi, I really like that there is an admin taking the time to provide insight to us all. Thanks!
My question…in late December 2016 I transferred from my old domain twoclownstripping.com to my new domain forkandfoot.com
At the time I made a mistake…my new domain was up and running but I messed up my redirects for a few days and my old domain also expired for a few days.
In the first week of January it was all back to normal, but ever since I have found that my DA has dropped from around 35 (old domain) to 1 (new domain – forkandfoot.com). It’s been sitting on 1 for months now and says there are no back links. However I know there are numerous other sites backlinked to my previous domain, and the redirects should be pointing them to the new domain.
Can you explain what might be happening here? Thanks!
Hi Andrew,
It seems multiple things have happened that can really effect your rankings and domain authority:
Request webmasters to correct the old links (to make them point directly to the new URL) and fixing the status code should be your first priorities for now and in addition I would also focus on building new fresh links to your domain.
Success!
Thank you so much! We didn’t realise our host had used a 302 instead of a 301. It’s now been fixed and I hope to see a rise in authority :)
Regards,
Andrew.
Sure no problem!
Hi , we are getting “Couldn’t resolve host” ? What this means, as host is active and working?
Regards
M
Hi Mantas, please provide me with an URL, so I can have a look.
Cheers,
My blog went self hosted 5 months ago but for some reason the new domain isn’t showing on Moz at all. The old domain still is. I have done a 301 redirect and I don’t know how to resolve this issue at all. Any help would be appreciative.
Hi Amy, what was your DA and PA score before the redirect / domain switch?
Hi,
My PA/DA have been fluctuating from 26/13 to 1/1. One moment it is showing the values 26/13. Days later it shows 1/1. When I check again it is 26/13. Check again, it is 1/1.
Please help me out. Is my site losing its authority?
Hi Vincent, you probably experienced the same problem as Adam (see the comment below). So no worries, just a temporary issue.
Very nice and useful tool ,Admin. I use your website to check websites DA and PA as in seoprofiler website show only Link Influence,
Can you tell me why my domain/page authority has dropped from 25/37 to 0 & 0, two days ago it was fine? Everything is registering as 0 – please help.
Hey Adam,
Yesterday the MOZ API experienced some problems… just did a check for your websites and I get the same numbers you mention in your comment.
Please perform a new check and have a look at the results.
Where can I see mozRank for my blog / site?
On this page only displays the DA and PA score. Please help me.
Hi Sarumpun,
Just use the bulk Domain authority checker http://www.seoreviewtools.com/bulk-seomoz-authority-checker/ to get mozRank for your site.
This is a great tool to check Domain Authority of website. Could you please write about how to increase DA of website.
Hi Decimus,
Writing an article about increasing Domain and Page Authority is on the to-do-list. Unfortunately this is currently a pretty long list, but I’m working on it ;-)
Thanks for the feedback!
Sometimes when I try to check the authority of a website appears 0, but I double check with another tool and give me a different mark. Just to let you know about the issue, but nothing important. I really like this site btw, nice job :)
Hi,
Thanks for pointing out this issue. The 0 DA / PA score seems to appear when the number of request rate limit to the MOZ API is exceeded.
I can’t fix this problem, but when you get the 0 score result, just refresh the results and 99% of the time the tool will return the right score.
Hey social share score of my homepage is 0 is it true?
There seems to be a bug, when retrieving social share numbers for the homepage.Thanks for mentioning it and I’ll solve this problem as soon as possible.
See updated status..
Hi,
Just solved this issue. Please give the tool another run and get the accurate total share count for your homepage.
Thanks for pointing out this issue!
Hi
My domain is only 3 months old, why it is showing 5 years as URL age….?
Hi DN,
The Website Authority checker is built to return “Website Age” instead of “Domain Age”.
Please checkout the tool description for further background information.
Hi. The tool is saying my website is only 2 months old. It’s in fact just over a year old and the specific domain I’m using it 9 months old.
Is this a bug?
Thanks,
Morgan
Hi Morgan,
See the difference between Domain age and Website age…
To be clear this tool checks Website age, because this number is more likely to have an impact on your authority score.
how to improve domain authority , already got domain rating 33 ,?
Hi Fedi,
Edit: “get high quality backlinks”, is the short answer.

Hi,
Please help me to understand the External Links to Pages metrics which shows as 3.247, does it mean 3 decimal 247 OR 3 Thousand 2 Hundred Forty Seven links
Thanks in Advance.
Raghu
Hi Raghu,
3.247 external backlinks, translate to “three thousand two hundred forty seven” external backlinks.
Cheers!
Just updated to Facebook API (2.7) for social count support.
This tool is working perfectly. Thank You
Help this great free tool doesn’t seem to be working today. I have entered new sites and sites that I know have both domain and page authority.
Hi Silas,
Thanks for mentioning this issue, I’m working on a solution.
And I’ll post an update when the problem is solved.
Jasja ter Horst
Just contacted MOZ today and they’ve solved the issue!
Thanks for the valuable informations discussed in the comments.
Hi there,
This tool is very helpfull! I have one question, though..
For a domain (alkuplus.nl), this tool states 744 ‘external links to domain’. When I check the same domain in majestic.com, they state 192 ‘external backlinks’. What’s the difference between these metrics?
Hi Rianne,
I’ve also checked your domain with this tool (running on the Moz API) and compared it to the results from Majestic SEO. And the different number of backlinks can be explained because you’re comparing “Total links” (this tool 744) and “Linking domains” (Majectic 192).
The total link count is expected to be higher than the linking domains number, because some domains link multiple times to your website, causing the total link count to be much higher.
I hope this answers your question and if not just let me know ;-)
Thank you for your help. I’m still confused though. Because:
– your tool is stating the metric ‘External links to domain’ > total links?
– Majestic is stating the metric ‘External backlinks’ > linking domains
Regarding this explanation, I’m wondering if you can tell me what Majestic means by the metric ‘referring domains’. What’s the difference between ‘referring domains’ and ‘external backlinks’ in Majestic?
Hi Rianne,
No problem.
When comparing these metrics (which is always a bit problematic as mentioned in the comments below), you can intrepid them like this.
Website Authority Checker: External links to domain = Total external links pointing at the exact web site URL (example.com)
Majestic: External backlinks = Total external links pointing to any page of your website (example.com, example.com/products, example.com/category, etc.)
Furthermore the Website Authority Checker reports equity links. This means only links which pass link value are returned (excluding nofollow links, 302 redirects, etc.). For this reason the number of reported links by this tool will almost always be smaller than the numbers returned by other tools.
The advantage of this setup is, you’re looking at the important links and not just at quantity.
More about equity links: http://www.seoreviewtools.com/what-is-link-equity/
Hope this helps ;-)
Thank you for your detailed explanation! It makes sense now :)
Different tools and sites will give you different results. This depends on the size of the database of these sites as well on the techniques these sites use. One simple method is also to check google this way: “www.yoursite.com”.
Hi Thomas,
Your comment is spot on. You will always see differences when comparing the results from, for example: Ahrefs, Majestic SEO, MOZ (Open Site Explorer) / this tool, because all these tools use their own datasets.
To my opinion you should focus on the high quality backlinks instead of just the quantity of links pointing to a web site, when judging a backlink profile.
Hey Jasja
My domain is only 3 months old, why it is showing 5 years as URL age….?
Hi,
I did a check for your domain and the archive.org shows data from 2011. This probably means someone else used the domain before.
Great job with the update. I like having the Authority PageRank & Social stats all available and consistent in one single tool.
The tool works perfectly. Can you tell me how often MOZ updates these metrics? I have a site which has hundreds of links, but MOZ reports only 2 backlinks, so I was wondering if MOZ has the resources to update their index frequently.
Hi Roger, at MOZ they update their index pretty frequently (like every month).
The links you mention should surface, with upcoming index updates.
I checked my DA ,PR and PA. DA and PA is pretty good but my Google PageRank is zero. I would like to know how I can increase the PR of my blog.
Hey Ravinder,
Google has announce they won’t update PageRank any more (since December 2013). This means you shouldn’t focus on PR especially when looking at a relatively new site.
You should instead focus on becoming an authority within your market or niche. A good starting point is looking at the backlink profiles of your main competitors and see what you can learn from them.
How can I see the age of a website, when tool returns N/A ?
Hi Kata,
The website authority checker uses the Internet Archive / Wayback machine to find the first index date.
If this data isn’t found / doesn’t exist, the tool will return N/A (not available).
I see the tool still reports Page Rank, does Google still uses Page Rank ? Do sites still level up?
Hi Florin,
“Google PageRank is no longer shown by default, because Google announced they won’t update this metric any more.. read more about PageRank http://www.seoreviewtools.com/what-is-the-value-of-pagerank/. “
Thanks, its work for my blog.
Just put http:// in front of your domain.
I have 2 strong new TLD domains and not even MOZ can define the PA and DA. Why is that so?
It seems to be common with new TLDs…
Hey Martin,
Can you provide me with some background information:
Thanks.
Sure, i can!
There is still no visible PA and DA. Its show´s 1 – 1…
The domains are like 1 and 1,5 years old.
And there a many backlinks to those sites and i rank very good with them in the local google search.
Take this for example -> kleinheinz.pics
Looking forward to some insights… :/
Hi Martin Kleinheinz,
Sorry for the late response, but your comment got buried in my mailbox ;-). Just Did a Quick check and it seems it has something to do with the MOZ API because OpenSiteExplorer.org reports the same (0) numbers where other tools returned indeed +130 backlinks.
I’ll have a closer look at this issue, because I haven’t seen it before.
Thanks for the tool, it sure beats the paid one I currently use.
This tool is great. I think it is using MOZ for getting backlinks why not use majestic as they have a fresh index of back-links or ahrefs?
Hi Tanveer,
Your right, this tool uses MOZ backlink index to display the number of backlinks for a specific URL. Majestic and Ahrefs are also great tools to explore backlinks but they don’t offer a free API. At the moment I’m limited to the MOZ API but in the future I’ll try to offer backlink statistics from multiple sources.
I’ll keep you updated!
I just tried it and the tool gives really good insightful data.
Especially the social data is interesting to see.
All important factors analysed by a single tool. Great work :)
Thank you for this tool. Easy to use and the result is easy to read and understand.
Updates (01072015):
– Added Social media share score (URL and Domain level)
– Added URL age.
– Displaying Google PageRank is now an option
Let me know if you like / dislike this update..
Nice update Admin
Thanks, your welcome!
Great job with the update. I like having the Authority PageRank & Social stats all available and consistent in one single tool.
Hi, this is a fab tool- thank you! I know you did an update today and it did reflect in my DA improving from 13 to 18 but when I checked the backlinks there were only 2 new ones on there and I know that I have quite a few links from other prominent sites. Was just wondering why it doesn’t reflect these? Sorry, I’m not techy at all but would just like to know how I can improve my site’s ranking further as thought I was doing the right thing by getting links from quality sites. Thanks in advance.
Amy
Hi Amy, nice improvement.
Moz just did an update of their mozscape API and many sites will see a shift in PA and DA.
If you’re looking at the Domain Authority statistics returned by this tool you’ll see the exact number of external equity links pointing to the root of your domain.
This can cause the number of returned links to be lower than expected.
Some examples:
I hope this answers your question.
Thank you! I think they must have been no-follow links. Thanks for the advice. :-)
No problem!
Is the number of years a domain has been established matter much in terms of ranking? For example how does it effect ones page ranking in the google search results?
Hey Peter,
An old domain with a very low Domain Authority does tell you this domain hasn’t gathered a lot of authority over the years. But a website which has a high authority and age, is most likely a trustworthy domain with good ranking potential. The last example; a site with a high Domain Authority, which has just been on-line for a couple of years. In this case, the owner / company behind it probably created link worthy content, established important on-line social connections or found other great ways to receive backlinks.
To conclude, I wouldn’t consider website age a direct ranking factor. Website age is especially useful to put other metrics in perspective (like Domain Authority & Page Authority).
Hi admin,
How often is this updated. I have a blog about 10 -15 days old and created some backlinks. I have some questions regarding that. Doesit show comment backlinks? Does it show nofollow and social media backlinks as well? How long before my domain gains some amount of authority
Thanks
Hi Navneet,
Good question. To answer it you have to look at the different metrics returned by this tool:
The last PR update was back in December 2013 and Google announced it probably won’t update PR in the feature (according to John Mueller form Google). That being said you can still use PageRank to get an impression of the authority for a specific webpage.
Domain Authority (DA) is a metric developed by Moz based on their Mozscape Index which is updated about every month. You find the exact dates over here: http://moz.com/products/api/updates. Your domain authority score will probably change around every 3 to 4 months, if significant changes occurred within your backlink profile
So in your specific case you should focus on Domain Authority, because it’s a new site. And you can expect to see changes in a couple of months (3 – 4 months).
Thanks Admin,
It is great to see that you share your future index dates and show us a detailed view as well.
Yes, After google’s decision of not making the pagerank public. Domain authority is the best way to quantify your SEO efforts.
Thanks for the quick reply :)
Your welcome!
For the record, this tool is using the Mozscape API to display Domain Authority, Page Authority and backlinks. And thereby relies on the Mozscape API for updates.
perfect tool to check pa and da of domain
Update: I just added progress bar support to visualize Page Rank, Page Authority and Domain Authority.
Thanks for the cool tool, it works fine and without any issue. I will surely check back when i establish my site fully :)
Update: new feature added (Website age)
Awesome site and tools. Thanks !!
Hi,
Without http:// or https:// the tool is not working…
Hi Rishi Kumar,
That´s true.. I use HTML5 form field validation and it needs the scheme / Hypertext Transfer Protocol (HTTP) to validate an URL.
So this means your input should contain the full URL ;-)
Its not showing google page rank for my blog :(
Just shows empty box…. :((
hi Shubham,
Thanks for pointing out this bug.
I know the issue exists when a PageRank 0 is returned.The value is shown outside the box, when I’ve got some spare time I’ll look into it. For now you know your PR = 0.
Problem solved, see the repose below.
Just had the time to fix this problem. It was just a little bug caused by CURL returning an errno 0.
Problem solved..
I wonder how you can increase Google Page Rank. I suppose a score of “1” is not very good…
Hey Brad,
The simple answer is:
The full answer is:
You can use the backlink tool to check the backlink profile of your, top ranking, competitors to find relevant link opportunities.
Hi, Ican you tell me why I can’t check my facebook page? Btw is it possible to check facebook page of my profile? thanks in advanced
Hey Klinik,
You currently can’t check the https:// version of a domain, so try http:// instead (for now).
I’ll look for a solution to make it possible to check both versions.
Can you tell me why this tool is showing two reports for my website?
Hey Engr,
The website authority tool displays your domain and page level authority statistics. When you add your root domain you get two different reports:
This tool doesn’t work.
It throws this error –
Sorry Api connection currently not available, please try again shortly.. or use the Bulk SEOMoz Authority checker instead.
Hi Yogesh,
The message you received isn’t an error but a suggestion returned by the tool when the API connection fails. There are some problems with the stability of the API (I’ll look into that). When you get this message, just wait a couple of minutes or use the http://www.seoreviewtools.com/bulk-seomoz-authority-checker/ to retrieve the Page Authority and Domain Authority for your page.
The Bulk SEOMoz Authority checker is using a different and more stable API.
The Website Authority Checker has been updated and now runs on the Moz API. This means you should get results 99% of the time and no more errors!
This tool is working perfectly. no issues.
I’m entering the URL for my web page but a message keeps appearing asking me to enter a URL
Hey Toks, did you enter your full URL, including http:// ?
