Your index page should not be the only one optimized when creating a website
. You should also focus on the sub pages in your website. One big mistake that webmasters make is not using the sub pages correctly. These should be created as landing pages meaning when a visitor comes to your sub page from a major search engine they should be able to navigate around. If you want to optimize your sub pages then make sure to fill out the meta titles and meta descriptions. The more sub pages you have optimized the more places you will be able to rank well in the search engines. One thing that I like to do is after searching Google Adwords keyword tool take some of the keywords getting less traffic and place them in your sub pages title, description, and within the content.
