My #1 SEO technique revealed (but I need some help)

[AmazeMe]

One of my favorite ways to find keywords for SEO is to compile all of my competitor's categories from their blogs.

But sometimes, these categories are hidden within WordPress.

Question: Do you know of any sort of secret hiding place that displays any WordPress categories in the same location (or URL)?

For example, sometimes I hit gold by going to something like:
w. w. w.blog-name-here.com/category

... This usually throws up a 404 error page... and some times there's a listing of categories.

Can you help me with this?

try site/category that's the default for WP, then there at the bottom of each post the will be an in:x. x is the category.

Other than that you can try checking the sites rss feed

I think it's not a good practice. But there's some WP plugins that lets you hide categories on the website.
