When I posted Bella’s question at Four Quick SEO Tips yesturday I mentioned that I love to hear from everybody and that your questions are always appreciated. I want to thank Lee from http://myblog2day.com/ for posting the following link building question and take a moment to answer.

Thanks for sharing these Chris! I have a question about getting links from high PR site. In fact, I’m doing a new link building by register in high PR site (PR4-PR7) and insert my link in the profile that points to my blog, so the profile page will be PR0 or no PR at all. In this case, is this type of link increases the blog ranking for the keyword since it’s just a PR0 page links to the blog (Even though people said that is a PR4-PR7 site link to the blog)?

Regards,
Lee

What Lee’s asking about is the value of linking from a low PageRank page on a high PageRank website and if that has any value at all but before I answer, I want to explain that concept to some people who may not be aware of the difference.

PageRank, as we’ve discussed before is a rank (0-10) which Google assigns every indexed webpage and website on the planet. Every time a page links to another page, it deducts a portion of it’s own PageRank and gives it to the receiving page. If it links to 10 pages from a single page, it transfers 1/10th of its PageRank value to each of the 10 links.

Now, a page may appear in the Google Tool bar as a PR0, even if it’s on a PR5 website but that’s an error or more specifically a flaw in the update routines but one that is well enough known that it doesn’t impact SEO value transfers within Google. The reason is simple, if my website hosts a page which is linked to from other pages on my website and my website has a PR value of 5, all pages which are links and interlinked must also by default have an assumed PR value of 5. In lay mens terms? If the domain your posting to has a PR value, all the pages interlinked on that website have the same PR value.

So to answer Lee’s question, if the website you’re posting your link on has a high PR ranking don’t worry so much about the rank of an individual page. Instead worry if people who are visiting that page are likely to find value in your website being listed there!

Remember, if you have a question I’d love to answer it for you!
