I need to seo the key word work at home for my website www.ihomeworks.net?

[Subash]

This is called your money site - http://www.ihomeworks.net
identify the niche(core activity of your site) of your money site.

open google adwords create an account and start using keyword tool

now you know the core activity of your site(i,e doing hoeworks)

search keywords related to homeworks in keyword tool
Ex:homeworks online,best homeworks online...etc

things to be noted in finding keywords through the keyword tool
search volume should me more and competition should be medium or low for the selected keywords

prepare keywords below 180 characters for the home page
for internal pages select unique keywords as per the content in the page..

finally add publish live

if all the above mentioned steps were done correctly within short time your page will be indexed in google and you will get good traffic after few days
