As an experienced person of SEO I want to share here some facts which should avoid by us.I hope that this will help some of the newcomers a lot..

choosing a title that has no relation to the content on the page
using extremely lengthy titles that are unhelpful to users
using a single title tag across all of your site’s pages or a large group of pages
stuffing unneeded keywords in your title tags
writing description meta tag that has no relation to the content on the page
Multiple domains
Multiple identical sites
Cross Linking

Very well said,search engine optimation is everybody’s business here in the web,there are a lot of ways to do it like,backlinks and search engine submissions and i think your post will surely add more ways to get the most sought after page rank.

Absolutely right.

But i am a bit confused due to multiple domains. What is this ?

Can you describe a bit about it?

Thanks :)

When you say cross linking, are you referring to reciprocal links in which you exchange links with another web site of similar content? I've stopped doing this but used to do it and thought it wasn't bad but wasn't the best way either.

In latest they have advised to avoid using websites which takes huge time to load..

link exchange is not a good work because if you do more link exchange for your site  it is harmful for your site after some time your site promotion not work and your site not get the traffic
