Hi, I have a problem I am really concern about. I have a website which had 700 pages indexed until a month ago. Slowly , It dropped down to 187. The website is 4 months old , But still , I am worried that they will never be indexed again. I have submitted a xml sitemap to google webmaster tools , But I am not sure it did help. What should I do? Any help will be appreciated. Thanks.
Try to get more backlinks for your site. The more backlinks you have, the more your pages will be indexed.
Make sure that you don't have duplicate content on your website. Apart from getting links to your homepage, also get links to your internal pages.
Do nothing. Same thing happened to me. My site had 15000 pages index then it started dropping & hit the 4300 mark (it was like Nasdaq). But now it is getting indexed again. currently it has index back 9500 pages.
do you have any errors in google webmaster tools for your sitemap? just keep building deep links and you'll be fine..
