Please help me with next info: How long does it take a newwebsite to appear in google search. My website is already 3 weeks up and i don't find it anywhere.
How many back links is ok for a website to advance in google search?
Indexing time varies, but because your site is new, it will take a long time. The time gets even longer if you sit there waiting for it to be indexed. You should list the site in some RSS directories and social book markingsites.
There is also something new I have discovered, and that is to create a Google Plus business page and add your posts to the page. From my experience, Google indexes my posts in less than 5 minutes using this method.
Get your website link in as many well known sites as you can so it can be picked up by Google.
