1) How does javascript affect on-page SEO 2) What is the best SEO technique to use while SEOing AJAX heavy websites? 3) How do we incorporate and develop a real-time SEO solution? Thanks in advance the person who replies
Regarding javascripts, search engines cannot crawl javascript codes so the output generated through javascripts will not be indexed by search engines. If you have menus generated using javascript then those will not be visible to search engines, the same applies to other sections which use javascripts.
Google also suggests minimize the use of Javascript. While Ajax is very cool to have on the website, the crawling would be a problem specially when certain data are retrieved by client-side functions.
