Elite Site Optimizer audit website crawls every web page on a website just like Google's search engine does. The data it provides can be exported to a . CSV format and issues can be fixed on each individual web page. Once on-page SEO analysis issues are resolved, another web crawl can be performed on the website and the reports can be run again, making sure all issues are fully repaired. The webmaster can also compare the live website to a development or staging build of the website to keep track of existing issues and ensure no new issues slip through testing unnoticed. Webmasters can also compare the results of crawls run on two separate dates.
