Hi to All, My keywords were ranking quite well position in Google SERP, but from last one month, it is not in google SERP, but my pages are chached by google regularly. please suggest me what to do
I think you used any where black hat technique then google drop your ranking. Don't use Spamming or black hat technique.
If your site is new, there are many case that new sites rank high immediately then dropped in rankings. You can regain high position if you continuously do strong link building and making quality contents.
Google's results are never constant and can change as soon as it finds more useful content. That's why even if you have already gotten good results, it does not mean you can just leave it there and stop optimizing your site. You may have had great content but competition is always out. Quality content and quality backlinks will always do you good.
Don't worry. Try to get more & more backlinks for your website...Then Google will retrieve your ranking position. Try to collect backlinks by article submission, link exchange etc. because it gives one-way high pr sites backlinks
HI! You have to update your site with new and unique content . publish your Articles and blogs daily you will regain your ranking.
You need to build some quality back links from different SEO sources. This will help in improving SERP of your website and will also be helpful in PR improvement.
