SEOmoz API

The SEOmoz APIs allow you to customize and integrate data from our dynamic Linkscape Index into your own applications. Because our index is never more than a month old, you are sure to get the freshest look at the web’s index available anywhere.

Power your internal search engine marketing tools with our data to optimize your domain, URL and link research for your business. Populate your critical internal reports with detailed, accurate information about how you and your competitors are performing on the web. Build your own commercial tools platform to help your customers with search engine marketing, social media, and domaining, any activity that requires detailed knowledge about the power of a page, domain or link on the web. Integrate our data into your web directory to provide more value to users and drive more traffic. Create free tools on your website using our data to help drive traffic to your site and collect leads.
