The Value of Links and Targeted Link Text
By Phil Craven
A wander around the various search engine optimization forums
reveals that people are divided into two groups as to how
search engines rank web pages. One group insists that "content
is king", and the other insists that "link text is king". The
'content' group recommend adding good quality, on-topic,
optimized, content pages to the site and the rankings will
come. The 'link text' group recommend adding links to pages,
with the targeted search terms in the link text, and the
rankings will come.
So which group is right?
Certainly, the 'content' people are right in that good quality,
optimized, content pages will get some top rankings, but only if
the targeted search terms are not being competed over very much.
Page content is what search engines ranked pages on in the old
days, and they still do to some extent. But that began to change
when a couple of engines introduced "link popularity" (linkpop)
into the equation. The more links that a page had pointing to
it, the better it did in the rankings. Even so, content was
still the king.
Then along came Google with a new idea. Instead of using links
to a page as simply an additional ranking factor, they based
their whole engine on them, to the extent that they called
their engine a "Hypertextual Web Search Engine" - "hyper" as in
hyperlink (clickable link), and "textual" as in the link text
that is clicked on. The Google search engine was, and is, based
on links and link text (sometimes called "anchor text"). Google's
idea was that a link from one page to another page is a vote by
one page for the other page, thus making the recipient page more
important. They also decided that the clickable link text is
likely to provide an honest and condensed idea of what the
recipient page is about.
With their new idea, the relevancy of Google's search results
far surpassed that of the other engines, and Google grew to
become the #1 search engine of them all. The other engines had
no choice but to follow suit. Page content still plays a part in
the rankings, but the biggest single ranking factor of all is
link text. Links to a page, with targeted link text, can push
the page to the top of the rankings. As an example, type
"miserable failure" (without quotes) into Google and look at
the #1 result.
An even better example is a search on Google for "computers"
(without quotes). Look at the source code of the #2 result
(Apple). The word "computers" doesn't appear anywhere in the
page, and yet "computers" is a very competitive search term.
Google's cache of the page states that "These terms only appear
in links pointing to this page: computers". It is the link text
in the links pointing to that page that has pushed it into the
#2 position for a very competitive search term.
Those are examples of the ranking power of link text. The reason
it happens is that Google stores each word on a page in what
they call "barrels". But they have two groups of barrels. The
small group contains words that occured in URLs, Titles, and
link text. The large group of barrels contains words that
occured anywhere. When processing a search query, the Google
engine first tries to find enough results (about 40,000) from
the small group of barrels that contains link text words. If
they can compile enough results from there, they don't even look
in the group that contains the rest of the words on a page. The
group of word barrels that contain link text is the first place
that Google looks for results to a search query. That's why link
text is such a powerful ranking factor, and it's why link text
alone can push the recipient page to the top of the rankings for
competitive search terms.
Do All Links Count?
----------------------
There is some discussion around the seo forums as to whether or
not some links count less than others. One idea is that multiple
links from the same site, whether internal or from external
sites, are devalued. Another idea is that internal links count
less than external links. There may be some truth in the ideas,
but they are just ideas and nobody outside Google really knows,
so it is best to assume that all links to a page count.
Link Acquisition
Acquiring links can be time-consuming and tedious. There are
a number of ways to get them, some being easier than others.
Wherever you get them, make sure that their link text is the
search term that you are targeting, and that each link points
to the page you are promoting for the particular search term.
Pointing all the links to your home page, with various target
search terms, won't achieve the same as pointing targeted links
at specific pages within the site.
Forums
Join forums and place links to your site(s) in your signature
line. Use your main search terms as the link text. But before
spending time writing lots of posts with your signature line in
each post, make sure that the forum is spiderable by checking
the robots.txt file, and make sure that non-members don't have
session IDs in the URLs (some engines won't spider URLs with
session IDs in them). Also make sure that links in signature
lines are not hidden from spiders (view the source code to make
sure that signature links are in plain HTML and point directly
to the site).
Link Exchange Centers
Find and join free link exchange centers like LinkPartners.com
(http://www.linkpartners.com). There you can find a categorized
directory of websites that also want to exchange links. Be
careful not to sign up with FFA (Free For All) sites because
they are mostly email address gatherers and you can expect a
sudden increase in email spam soon after you sign up. Also,
only sign up with centers where you can approach other sites
personally, and where they can approach you personally.
Do not join any link farms!!! Link farms, such as LinksToYou.com,
sound excellent, but search engines (Google in particular)
disapprove of them as blatant attempts to manipulate the rankings
and they will penalize sites that use them. Once a site has been
penalized, it is very difficult to get the penalty lifted, so
avoid all link farms.
Email Requests
(a) Search on Google for your main search terms and find the
websites that are competing with you. Then find which sites
link to them by searching "link:www.competitor-domain.com".
Email them and ask for a link exchange.
(b) Search on Google for websites that are related to your
site's topic, but not direct competitors, and ask them for a
link exchange.
Buy Them
There are websites that want to sell links, and often the link
will be placed on multiple pages, or all pages within the site.
It's possible to approach individual sites where you would like
your links to appear, but it is much quicker, easier and more
reliable to use a middle-man service (or broker).
Link brokers offer links for sale on behalf of other websites
(you could use the service to sell links on your site!). With
these services, it is usual to be able to choose the topic of
the website(s) where you want to place your links. One such
reputable broker is http://www.textlinkbrokerage.com
Auctions
There are even links for sale by public auction, such as the
one at LinkAdage Auctions (http://www.linkadage.com).
Summary
Inbound links are important for websites that want to move up
the rankings. Inbound links, with the right link text,
are essential for achieving top rankings when there is any
competition for the search terms.
Most websites do not naturally attract links, and link
acquisition can be time-consuming, tedious, and frustrating.
Many websites that are approached by email will say no, but some
will say yes. For top rankings, it is a almost essential to take
the time and get many inbound links. It should be treated as an
ongoing task.
