How Important Is PageRank?

When a user types in a search query, the search engine’s number one goal is to return results that are high-quality, relevant, and able to best give them what they want. One of the 200+ factors Google takes into consideration to determine which web pages best fit the bill is PageRank.

Page-Rank is what Google uses to determine the importance of a web page. It's one of many factors used to determine which pages appear in search results. PageRank is also sometimes referred to by the slang term "Google juice

The History of PageRank

Page-Rank was developed by Google founders Larry Page and Sergey Brin at Stanford. At the time that Page and Brin met, search engines typically linked to pages that had the highest keyword density, which meant people could game the system by repeating the same phrase over and over to attract higher search page results.

PageRank is patented by Stanford, and the name PageRank likely comes from LarryPage.

What is “Link Juice” and What are PageRank _Points?

When Site A links to your web page, Google sees this as Site A endorsing, or casting a vote for, your page. Google takes into consideration all of these link votes (i.e., the website’s link profile) to draw conclusions about the relevance and significance of individual web pages and your website as a whole. This is the basic concept behind PageRank.

When a website links to your site, or when you link internally from one of your pages to another, the link passes PageRank points. This passing of PageRank points is also commonly called “link juice” transfer.

The amount of link juice passed depends on two things: the number of Page-Rank points of the web page housing the link, and the total number of links on the web page that are passing PageRank. It’s worth noting here that while Google will give every website a public-facing PageRank score that is between 1 and 10, the “points” each page accumulates from the link juice passed by high-value inbound links can – and do – significantly surpass ten. For instance, web pages on the most powerful and significant websites can pass link juice points in the hundreds or thousands. To keep the rating system concise Google uses a lot of math (ask me in the comments if you want to hear about it) to correlate very large (and very small) PageRank values with a neat and clean 1–10 rating scale.

How Link Juice is Passed

 Every web page has a limited amount of link juice it can pass, and the top of that limit is the total PageRank points that page has accrued. So, a web page with 20 accrued Page-Rank points cannot pass more than 20 points of link juice per page. If a page with 20 Page-Rank points links to one other page, that one link will transfer the full amount of link juice to that one other web page. But if a page with 20 Page Rank points links to five web pages (internal or external), each link will only transfer one-fifth of the link juice. Google applies a decay value to every pass, so the actual numbers will be a little less than our diagram shows below. But to explain the PageRank concept simply, the formula is PR points divided by number of on-page links, or in this case, 20 divided by 5:

 

PagkRank follow

Visualize it: This diagram shows what it looks like when a web page with 20 Page-Rank points links out to 5 other web pages that, accordingly, each receive approximately 4 PageRank points.

What if you want to link to several resources to aid user experience, but you don’t want to dilute your link juice transfer? You can tell Google not to pass PageRank by amending some links with a rel=”nofollow” tag. So if you have a Page-Rank 18 web page that has 4 links on a page and three of those links have rel=”nofollow” tags, the one link that doesn’t have a rel=”nofollow” tag will get the full 18 points of link juice.

How Can I Increase My PageRank?

If you'd like to increase your PageRank, you need to have "backlinks," or other people linking to your website. The best way to increase your Page-Rank is to have quality content that other people want to link.

How Important Is PageRank?

PageRank is one of many factors that determines where your web page appears in search result ranking, but if all other factors are equal, PageRank can have significant impact on your Google rankings

Warning : Now that you understand basically how PageRank works, we don’t want to give you the wrong idea. It’s not true that the more links you have, the better off you are. In today’s world, QUALITY is more important than quantity. Google penalties have caused many web owners to not only stop link building, but start link pruning instead. Poor quality links (i.e., links from spam or off-topic sites) are like poison and can kill your search engine rankings. Only links from quality sites, and pages that are relevant to your website, will appear natural and not be subject to penalty. So never try to buy or solicit links – earn them naturally or not at all.
