Simple Mathematical explanation of website backlinks

If you happen to be the reader of this post, and may not be familiar with Page ranking or backlinks, here is a simple and quick explanation. Google performs a calculation on backlinks that point to a particular website. Yes, the amazing machine – Google will crawl every website in the world and cache any hyperlinks to your website for example. Then, a page rank is assigned to a website. The page rank is primarily based on the effectiveness of those backlinks.
So which one is better? More backlinks or better quality backlinks that have a higher page ranking? The answer is both. Back in the day, before the algorithm became sophisticated, there was much more spamming which included excessive amounts of backlinks that had no relevance. That has since changed, now relevance matters… 

For example, if a semiconductor website has two back links, each from a PR2 website, and one of those website is relevant in subject matter (such as another semiconductor company) and the other backlink comes from a non-profit for helping lost dogs – then, the relevant backlink receives a MUCH higher score.

In summary, Page ranking is a ranking system ( or link analysis algorithm ) that calculates the accumulation of backlink relevancy coupled with a few other more minor website design factors.
Now, to explain the math part of this ranking system. The total ranking for backlinks is not just the sum of link relevancy, that would be way too easy to understand and follow.
It is logarithmic, meaning it uses the logarithm of a physical quantity instead of the actual quantity.

Therefore, the more – higher ranked back links you have, the better. Although, in a real world situation, if you are reading this, you are most likely not a powerhouse enterprise size company that has thousand of affiliates and customers along with a million dollar website marketing budget. You most likely are in the same boat as most other small business websites. In that the number of backlinks most likely ranges anywhere from 30 to 1000 backlinks.

There are some free seo tools out there that will not only show you your backlinks, but also display the PR value of those backlinks. (A PR backlink tool is actually provided on the FindMyCompany website). In this scenario, your choices are to engage in an SEO campaign or sign up for some link building services that may or may not help you! For example, 50 high PR backlinks are FAR MORE powerful than 1000 low or 0 PR backlinks from bogus directories and other link campaign sources that have no page rank value. The difference involved between a professional seo link building campaign and other cheaper link building services is that professional seo creates link exchanges with other relevant partner websites. In other words, real business websites and not link directories. SEO firms will solicit a link exchange with other relevant companies and exchange links. This results is a permanent link (as long as that company stays in business) that will provide a high scoring backlink. Other cheaper link building services will create several link directory links. The problem with this is, when evaluating the overall number of links a given website has, it may be difficult and take more budget to counteract bad links that have been created with good ones.

In summary, you can take a look at your backlinks with their PR rating and relevancy, it is public knowledge with the right seo tool. Then, determine your budget and try to increase the number of backlink while at the same time making sure they are quality backlinks. There are several exchange services that allow a free link exchange with partners if your page rank is already at a certain level. If the budget is not there to do a month seo campaign, then there is always the option of purchase a few of the know high PR back links that do help. For example, a Yahoo Paid directory link provides a great PR5 backlink and costs $300. Business.com also provides a similar backlink and costs $500 the last time I checked… seo company
