Improve Your Web Site’s SEO With SEOmoz’s Free API

Matthew Casperson, March 11th, 2010

SEOmozSearch Engine Optimization, or SEO, is vital to any successful website. The team at SEOmoz are experts in this field and now offer a number of premium SEO tools including the recently released Open Site Explorer, which provides a wealth of information on backlinks and link popularity. Now the same information available through Open Site Explorer can be accessed via a new, free API. From their announcement:

The launch of Open Site Explorer last week opens up a lot of link data, filters, and anchor text to a much wider audience than we’ve ever had before.  In that same vein, today we’re announcing our new and improved SEOmoz Free API.

Any registered (it’s free) SEOmoz member can visit our API Portal and get an API key that gives you access to:

  • Data for any URL in our index including
    • Domain and Page Authority
    • mozRank
    • total link count
    • external, followed link count
  • The first 500 links to any page, sub domain or domain
  • Filtering on those links: 301s, Follows, External, etc.
  • The first 3 domains linking to any page, sub domain or domain
  • The first 3 anchor text terms or phrases in links to any page, sub domain or domain

Open Site Exolorer

Reaction to Open Site Explorer has been good (like here and here), and the API Moz API is already being put to use by a number of parters including Buzzstream, Brandwatch, HubSpot’s Grader Suite and Quirk’s Search Status toolbar. New developers will find plenty of source code and examples on this wiki.

Those looking for more detailed information can make use of the SEOmoz paid API, which includes additional features seen in Open Site Explorer Pro.

You can find more information in our SEOmoz API profile, along with links to a dozen other SEO-related APIs.

Thanks for the TIP. Although I’ve been reading SEOMOZ for quite some time now – didn’t know that their API is FREE as most of their tools are paid!
So thanks again for the heads-up.

Studies on SEO’s 16 years and never felt that there is something to learn. I worked and still work a part-time as a freelancer on RentACoder (User Creative Trend, where currently 52) to many optimization projects, most of the content. Personally, I think it’s a complex puzzle, made of many small pieces, interdependent. I thought to write a short guide that summarized all these pieces, which are necessary in a comprehensive SEO plan. Being late, it could be forgotten a few items, so please, contribute and correct me. http://stylishfirst.com/seo-plan-completed/

This kind of data is very exciting. I’m glad to see the API industry around it emerging. I think there are a lot of neat mashups just waiting for smart developers to build :)

Hello! I know this is kind of off topic but I was wondering if you knew where I could get a captcha plugin for my comment form? I’m using the same blog platform as yours and I’m having problems finding one? Thanks a lot!

No doubt, “Open site explorer” is a wonderful tool. I have had been looking for a backlink analysis tool for quite a long time. Thanks for developing such a nice tool.

Hi there. I noticed your blog title, “Improve Your Web Site’s SEO With SEOmoz’s Free API” does not really reflect the content of your web-site. When creating your site title, do you think it’s most beneficial to write it for Search engine optimisation or for your audience? This is one thing I’ve been battling with simply because I want good search rankings but at the same time I want the best quality for my website visitors.
