WordPress Technical Support Hi Dave,
I got to this site searching for Silo Plugins.

I found out that there are 3-4 people who made Silo ready plugins/themes and you are one of them.

One of the people who made a silo plugin is:

They give away their plugin, but their services are extremely expensive and I could not afford to pay their monthly fees. They have a keyword research service called “the krakken” which finds the low competitive high converting keywords for your silo and builds all the map of keywords for you. Hence, what it does is: it finds you all the keywords for your mini niche site so you rank it fast and easy.

Since this tool is out of my range and does not seem to work as they state(tried their free silo plugin and broke my site), my question is:
What is the best way to find main keywords to build the silos?

I need to find keywords to build mini sites around and be able to rank those keywords with ease. And of course those keywords need to be commercial terms. I am currently using keyword planner’s group of keywords to find the main terms, and sub-terms, but I think I need something better than that.

Let me know if you can help me with this and if you also have a link building program you recommend.
