III. Links – Another Important SEO Item
1. Why Links Are
Important
Probably the word that associates best with Web is “links”.
That is what hypertext is all about – you link to pages you
like and get linked by pages that like your site. Actually, the Web
is woven out of interconnected pages and spiders follow the links,
when indexing the Web. If not many sites link to you, then it might
take ages for search engines to find your site and even if they find
you, it is unlikely that you will have high rankings because the
quality and quantity of links is part of the algorithms of search
engines for calculating relevancy.
2. Inbound
and Outbound Links
Put in layman's terms, there are two types of links that are
important for SEO – inbound and outbound links. Outbound
links are links that start from your site and lead to another
one, while inbound links, or backlinks, come from an
external site to yours, e.g. if a.com links to mydomain.com, the link
from a.com is an inbound link for mydomain.com.
Backlinks are very important because they are supposed to be a
measure of the popularity of your site among the Web audience. It is
necessary to say that not all backlinks are equal. There are good and
bad backlinks. Good backlinks are from reputable places - preferably
from sites with a similar theme. These links do boost search engine
ranking. Bad backlinks come from suspicious places – like link
farms – and are something to be avoided. Well, if you are
backlinked without your knowledge and consent, maybe you should drop
the Webmaster a line, asking him or her to remove the backlink.
If you are not heavily backlinked, don't
worry - buying links is an established practice and if you are
serious about getting to the top, you may need to consider it. But
before doing this, you should consider some free alternatives. For
instance, some of the good places where you can get quality backlinks
are Web directories like http://dmoz.org
or http://dir.yahoo.com.
First, look for suitable sites to backlink to you using the Backlinks Builder below.
After you identify potential backlinks, it's time to contact the Web master of the site and to
start negotiating terms. Sometimes you can agree to a barter deal –
i.e. a link exchange – they will put on their site N links to
your site and you will put on your site N links to their site - but
have in mind that this is a bad, risky deal and you should always try
to avoid it.
Internal links (i.e. links from one page to another page on the
same site) are also important but not as much as backlinks. In this
connection it is necessary to say, that using images for links might
be prettier but it is a SEO killer. Instead of having buttons for
links, use simple text links. Since search engines spider the text on
a page, they can't see all the designer miracles, like gradient
buttons or flash animations, so when possible, either avoid using
them, or provide a meaningful textual description in the <alt>
tag, as described next.
3. Anchor text
Anchor text is the most important item in a backlink. While it
does matter where a link comes from (i.e. a reputable place or a link
farm), what matters more is the actual text the link starts from. Put
simply, anchor text is the word(s) that you click on to open
the hyperlink – e.g. if we have the
best search engine, than “the best search engine” is
the anchor text for the hyperlink to google.com. You see that you
might have a backlink from a valuable site but if the anchor text is
something like “an example of a complete failure”, you
will hardly be happy with it.
When you check your backlinks, always check what their anchor text
is and if there is a keyword in it. It is a great SEO boost to have a
lot of backlinks from quality sites and the anchor text to include
our keywords. Check the anchor text of inbound
backlinks is with the Backlink Anchor Text Analyzer tool below.
Besides the anchor text itself, the text around it is also important.
4.
Link Practices That Are To Be Avoided
Similar to keyword stuffing, purchasing links in bulk is a
practice to be avoided. It gets suspicious if you bartered 1000 links
with another site in a day or two. What is more, search engines keep
track of link farms (sites that sell links in bulk) and since bought
links are a way to manipulate search results, this practice gets
punished by search engines. So avoid dealing with link farms because
it can cause more harm than do good. Also, outbound links from your
site to known Web spammers or “bad guys” are also to be
avoided.
As mentioned, link exchange is not a clean deal. Even if it boosts
your ranking, it can have many other negative aspects in the long
run. First, you do not know if the other party will keep their
promise – i.e. they might remove some of the links to you.
Second, they might change the context the link appears into. Third,
it is really suspicious if you seem to be “married” to
another site and 50% or more of your inbound and outbound links are
from/to this direction.
When links are concerned, one aspect to have in mind is the ratio
between inbound and outbound links. Generally speaking, if your
outbound links are ten times your inbound links, this is bad but it
also varies on a case by case basis. If you have a site that links to
news sources or has RSS feeds, then having many outbound links is the
inevitable price of fresh content.
