Google Deprecates AJAX | New Example SEM Tips No. 21

Google can now crawl JavaScript and CSS.

On October 14 Google announced that they have officially deprecated AJAX and confirmed that their search engine can now fully read, render, and follow JavaScript and CSS. So...what does this mean for an ecommerce website that is using AJAX, JavaScript, and / or CSS to power site content?

The good news is that unlike previous search algorithm shuffle ups, this change will not have a negative impact on current indexation of site content. AJAX generated content that is already indexed by search will not be de-indexed. However looking ahead, this may not continue to be the case. So to ensure full indexation as well as increase probability of higher rankings Google advises that ecommerce site owners:

  1. Verify that your site’s CSS and JavaScript files (typically located in the /css/ and /js/ directories) are accessible to crawl and are not blocked in your site’s robots.txt file.
  2. Follow SEO best practices for CSS and JavaScript, including script minification.
  3. With your site’s next update, move away from AJAX and toward the industry best practice of a progressive enhancement implementation.
