While writing this article I came across a case where there was a comment on a blog but it was not shown on the front end i.e. on the blog but when I saw its source code the comment was written there and that was because of AJAX. So as a normal SEO Expert someone could lost an opportunity to get a back-link from there but an smart SEO Professional having a little bit knowledge of JS and AJAX can have this opportunity in hand to get a back-link from there also.
Now the question arises, Does JavaScript affect SEO and if yes then how does it affect SEO. In the next section we are going to discuss about the effects of JavaScript on SEO:
