It's things like this that will get you penalized by the search engines

If every page on your site has the word bowling somewhere inside an article hyperlinked to your homepage, it's going to look awfully like it's done just for the sake of SEO, and the search engines will know that and discredit it (or worse, penalize you).

Also, anchor text with your keywords was most commonly used from various external websites ... not pages within your own website.

If you write an article about bowling on another site, link to your site in your signature. Search engines - AND HUMANS - both can sniff out search engine spam and what's called keyword stuffing.

If you do the best thing for your visitors and for people who read your articles on other sites, you'll get a lot farther.
