I change Meta tags my site and it got top three Google pages. Can Meta will help to get top #1 Google page within week. Now I am doing blogging and social networking, will help #1 or not. Google don't mind for Meta update in short time?
If your are doing off page optimization with the same keywords as in the on page optimization then it will automatically enhance your website traffic and searchability for that specific keywords or keyphrases.
Hey Congrats, you got top rankings!!!! Yes, metas section definitely work a lot to get #1 SERP. Now just carry on with off page efforts for the similar keywords as targeted in On-page. You will get lot of traffic and goals , gud luck!!!
meta tags don't carry THAT much weight. The title is the most important attribute. the meta keyword is pretty much ignored
