What about Google PageRank?

The Google toolbar will display a little green bar that shows the PageRank of a web site. There are many hints that the PageRank numbers in the toolbar are not updated and that Google uses other (internal) PageRank numbers to calculate the ranking of web sites. The official PageRank number that can be seen in the Google toolbar is more or less a marketing instrument for Google.

The PageRank of a web page shouldn't be the determining factor when choosing link partners. A link partner with a low PageRank that has a similar topic to your site will bring you much better visitors than an unrelated link partner with a high page rank.

If you see a good web site with good content that has a low PageRank you should trade links with that site if that web site is useful for your visitors. One day, that page might have a higher PageRank and it will still link back to you.

Ask yourself: Is the Busby SEO Test web site related to your site? Would it make sense for web surfers if they linked to you and you linked to them? Could visitors of the other web site be interested in your site? If you find a web site you would want to visit or your visitors would want to visit then link to it and ask for a link back to your site.

Just use common sense: If web sites that are related to your web site link to your web site, then your own web site must be important for that topic. If the links are useful for web site visitors, search engines will eventually find this out. Search engines do nothing but try to put common sense into a mathematical algorithm.
