Hey Ed...

I agree with Kelvin that baseball is a very broad niche.

Every team, every player throughout history, baseball equipment, posters, little league, there's got to be millions of baseball related keywords.

For example, how many types/brands of baseball gloves are there? You have left handed, right handed, catcher, fielder, first base gloves.

Aluminum bats, Louisville sluggers, these are all keywords that should be sprinkled through your network.

Another purpose of your network is for your pages to act as "doorway" pages and use plenty of keywords.

Again, remember that SEO is really about putting as many words on as many pages as possible, then link to those pages.

And this is what we're doing with the network, we're putting as many keywords on as many pages/blogs/lenses/sites as possible, then linking to those pages.

If your major topic is baseball, make a list of your keywords. Use some ranking and make two lists:

1. All keywords you came across in your research (remove the junk). Sprinkle these throughout your network. You'll want to try to use as many of these keywords as you can, as often as you can.

2. Your "best" keywords. Pound away at these, using them for basic SEO, article topics, anchor text, domain names, etc.
