OK, so my website www.comparebookies.com is really freaking me out. Can someone please take a look and tell me what they think?!! Since Sunday the homepage has disappeared off google index but the main subpages have remained. I take it therefore I haven't picked up some kind of ban from google. I have tried submitting the sitemap to google webmaster tools but it is coming back with a 404 error not found. Does anyone know what might be going on cos i've not got a clue and 3/4 people have taken a look and they don't know either! Why wouldn't google be touching the homepage when it checks out the rest of the site?!
make sure your site index.php file is readable check its permissions from the server it should be 755 to work and be red
It's giving a 404 Not found header. Somewhere in the code, you have forced the header to be 404 not found and that's why the google bot is not able to crawl this page. Find the code and delete it. As simple as that.
