Here's a simple strategy for building backlinks:

Building oneway backlinks from high PageRank sites is a MUST if you want to get your pages or blog into some high ranking search engine positions. The easiest way to get backlinks is to put them on the high PR sites yourself!

Hunt Old High PR Posts For Backlinks

1) Find a blog in your niche/market that's been around for at least a year. This also works with Digg.com posts.

2) Search through the archives and find the oldest, highest ranking PR pages.

3) Comment on those pages and don't forget to anchor your link with your main keyword. If you do this 5 times per day, you could build 5 easy PR 3, 4, and 5 backlinks per day.

You'll save a lot of time swapping for high PR backlinks. Plus these are one-way high PR links – the most valuable kind! If you can do this 10x per day for a year, then you'll easily get 3,650 backlinks from PR 3, 4, and 5 pages.

However, some blogs have no-follow set, which means search engines won't follow your URLs in your comments. But... tons are do-follow because bloggers are encouraging comments this way. Here's a good directory of blogs that follow: courtneytuttle.com/blogs-that-follow

Be sure to anchor your link with the keyword you want to rank high for in the search engines.
