Hi to all before two days google was showing my site on forst page and not it is showing on fourth page .what should I do for this
Your site should have a quality content and ensure that your site should have a duplicate content. Try to get backlinks from the quality websites.
I am sure you are using Mozilla Firefox so just delete cookies from your computer and then see the result.
cry ... no serious look at the first pages and ask yourself what do they have that my page don't and then start to beat them.
I guess you just have to wait for few days and keep on writing good content everyday. Highlight the keywords in your content if you feel they are important.
this could be just google dance where your ranking flactuates for some time and then goes back to normal. or it could be just your ranking that fell. i would say keep working on your site and keep building backlinks. there's not much you can do on where your site shows on search results other than just promoting it. sooner or later it will climb back up
Fluctuations in ranking is just normal. Just focus now on creating quality content in your site and link build from related sites.
Might take some time before you can get you old rankings back. Get more backlinks and unique content.
