Homepage Ranking Tips
Should You Rank Your Homepage For Keywords or A Brand?
The short and quick answer is Brand. Never ever rank the home page for keywords unless you have a thin website with just 10 pages or less. It is not recommended that you create a website with only 10 pages you will not be able to compete for high volume keywords. You want to create content and post to your blog. The more you post the better you will rank. You want to send link juice back to the home page via internal linking.
You also want to make your site more authority by placing links to other relevant and authority website.
