I had my website titles and metatags changed for all pages and 3 days before google was showing all the keywords and metatags and meta description in google the same as before. So I thought it takes some time for updating these things. But 2 days before I saw my titles changed, metatags and meta description changed in google listing and they were updated and I was on first page. Than after 6-7 hrs again it reverted back to old one and my ranking again went to old one and I went again on google on 2nd page for that particular keyword. If it was updated how it can revert back to old one?.
Google has some 20-30 data centres around the world. The data centres update at different rates. What you saw was the result of jumping from one data centre to another as you did your search.
How much time it takes to get that titles and metatags updated in google listing when I check cache history it says that last it was crawled at 20th nov. My pages are being crawled on daily basis but I dont understand why its not getting updated in google. How much time it takes normally?
It is because of the reason that some google servers didn't update your website change and still using the old data. The time to update all google server is entirely depends on the importance of your website (speed of crawling on your website).
As you change your meta tags and your site jumped but due to lack of back links, you are again on same position,so just build good back links .
I am submitting articles daily to goarticles or ezine. So is that considered as backlink? Also whenever website is completed we put our anchor text in bottom of website so that is also considered as backlink? I have done squildo new topic page Have bookmarked in digg etc. created videos in youtube. Doing advertise on facebook, twitter. what else can be ways to create back links
Google have 7 data centers, so that if you can search in Google then first time it comes different data center and second time it comes from another data center.
Google never look for Meta keywords and description. No effects will be on google search engine according to your Meta keywords & description change. Meta keywords & description were used in earlier time for search results. You no need to concentrate on those things that you have mentioned. Google dance might be the reason why your search engine results have changed for your website. I assumed that google have updated its algorithm two months before. read the article to know more about google dance @ http://buildmylink.com/articles/Google-Dance.html
