I changed my old targetted keyword due to wrong analysis. Its been two months. I was suggested on forum to wait for a few days before my site appears for new keyword. But it has disappeared for both the keywords. I've made new backlinks for new keyword but nothing. Any suggestion?
Which kind of backlinks were you building? Also what do you use to check your rankings? You have to stay away from home-made solutions if you are not completly sure about what are you doing. Usually 3 weeks are more than enough to see first results and to get indexed.
It all depends how soon search engine robots crawling your site. To make it crawl soon, you may generate quality backlinks by creating good articles, press releases and submit them into quality sites.
I was on #3 on first page for the keyword before. Its indexed now but no where till 10th page for neither old nor new keyword.
for this you have to provide complete analysis. i mean your website, your old keyword, and new keyword right now u are targetting. and make sure your on page is doing good and recent links are quality backlinks as well.
You was probably using cheap SEO methods on your site which have been highly penalized in the last months. You was slapped by Panda my friend. Focus on quality backlinks and you should be back very soon.
