First things first: What is Google PageRank? It is an algorithm
created by the founders of Google to estimate the importance of web
pages. The basic idea behind the PageRank algorithm is the fact that
a link (also called hyperlink or backlink) from page A to page B can
be seen as a vote of trust from page A to page B. The higher the
number of links pointing to a page, the higher its PageRank, and the
higher its rankings inside Google’s search results.
One detail that you need to keep in mind is that each link has a
specific value, which is determined by the PageRank of the page
where the link is located divided by the total number of outgoing
links on that page. For instance, if a page has a PageRank value of
8 and 4 outgoing links, each of those links will pass 2 points of
“link juice” (the calculations on the algorithm are more complex, but
this is the basic idea).
Most people focus on getting external links to increase their
PageRank, but they forget that internal links also pass link juice,
and this is how you can create PageRank within your websites.
Now let us use a simple example to illustrate the concept.
Suppose that you just created a website with one page only, the
homepage. At this point your website has a PageRank of 0, because it
is not even indexed by Google.
You then convince a friend to link to your website. The page where
the link is placed has a PageRank of 10 and 2 outgoing links, so
your website is receiving 5 points of link juice from that link.
Now your website would have a PageRank of 5. If you then proceed to
create a second page on your website, linking to it from the homepage,
that second page would also receive 5 points of PageRank from the
homepage link, increasing the total PageRank of your site to 10.
And there you go. By adding a second page to your site your managed
to actually create PageRank.
As we mentioned before, the calculations of the PageRank algorithm
are more complex, but the basic concept remains. That is, every time
Google indexes a new page from your website, the total PageRank
within your website will also increase, because that page will be
receiving link juice from the other internal pages of your site.
Getting external links is obviously essential to having a high
PageRank, but increasing the number of pages that Google indexes
from your site can also help, and most people neglect this.
For example, if you are trying to position your mini website on
the first search result for a specific keyword you could try
adding more pages of content to that site, to increase its overall
PageRank.
Finally, if you want to monitor how many pages Google is indexing
from your website, simply search for “site:yourdomain.com” on Google.
