Inbound Links Benefit Your Website
A link to your site is like a vote. If you randomly ask 10 people from 10 different locations what they thought of you or your site, and all said exactly the same thing, you’d walk away thinking something was fishy, or rigged, wouldn’t you? That’s how the search engines view links; if they are all nearly the same, pointing to the identical location, they will take note, and adjust (possibly penalize you) for it.
Simply put, what does it tell a search engine when all your links are coming in to the home page? Most probably that you have a shallow site, of little value, or that your links were generated by automation, rather than by the value of your site.
Conclusion: Make sure you’re getting links from as many pages as possible, but mix them up so that there is varied content. Also, get those links pointing to as many different pages as possible. The search engines will view this as natural, relevant, and give your site some extra “juice” when it comes to ranking.
