Level Structure of Pyramid Links:
Base Links
The foundation of your link pyramid are your base links. Like an actual pyramid, the foundation is the largest part of the structure.
Base links are links from niche article sites, social bookmarking sites, blog comments, deep inner pages, etc. In other words, base links are lower quality links.
It’s important that you have a lot of these links than any other kind of links, because Google’s algorithm thinks that this is “natural.†So you want to make sure your link pyramid has a solid foundation of base links.
Mid-Grade Links
The next level of our link pyramid are your mid-grade links. These are links from web sites that have more authority than the sites mentioned previously, but still may not be top-notch sites.
For example, sites that re-use EzineArticles content, mini sites and sales letter sites.
Mid-grade sites usually have a fair amount of backlinks to them , so they have a bit of authority. That’s why Google counts links coming from mid-grade sites more individually valuable than base site links.
Of course, that also means that you don’t need as many links from mid-grade sites as you do from base link sites.
Highest-Quality Links
For most long-tail keywords, you don’t even need these highest-quality link in your link pyramid. You can usually rank just fine with the base links and mid-grade links.
However, when you’re aiming higher, you need to collect them. “Highest-quality linksâ€, mean links from sites that already have a lot of links aimed at them. In Google’s eyes, site with a lot of links aimed at them have “authorityâ€, and anyone these “authority sites†link to must also be important.
The good news about getting highest-quality links is that a few links can make a big difference. So while these links are more difficult to acquire, you don’t need nearly as many of them to rank well for your keywords.
If you want excellent rankings in Google, it’s important that your link pyramid look natural. That means having a large number of base links, a lesser number of mid-grade links, and a few top-quality links.
