I have a website.Two months before I have deleted forum page from my site. Now the serp is down in google.. Is it the reason for deleting forum page? Thanks to u all!!!!!!
maybe your site got into google sandbox filter. Try submitting sitemap to google webmaster tools Good luck
Number of indexed pages is a fairly important factor so it could affect. Also, if the forum had some BL you lost them when you removed those pages if you didn't do a 301 redirect from the forum pages to the homepage.
