Link Exchange Scam
Author : Azani
I have written in an article about the importance to be linked
by other web site in order to increase your link popularity. It
is related to PageRank. The more back link you get, the higher
your PageRank will be, and the higher ranking you will get in
the search engine when somebody searches your keywords. You may
easily found many of webmasters really eager to exchange links
with each other especially when the other page's PageRank is
higher then them. Just type "link exchange" in Google you will
found thousands of them. But you must be very careful in
choosing web site to exchange link. Some of them just make your
PageRank going down into the drain by wasting your PageRank.
Firstly, what is PageRank? PageRank is a numeric value that
represents how important a page is on the web. When one page
links to another page, actually it is telling the search engine
the importance of other page. When more links a page got from
another page, it shows how important the page must be.
While surfing around looking for web sites to exchange link I
found some of webmasters doing bad thing to their link partner.
One example is to add the directory where those links are
located in disallow line in "robots.txt".
What exactly the webmaster want to do? Actually, the webmaster
restrict any search engine's robot from crawling into the
directory, in this case 'linkbuilder' directory. If you have
exchange link with this web site, the spider will not see your
link on the page, so it contribute nothing to you PageRank.
Obviously, your web page has a link to this web site (because
you exchange link with him) and the spider see it. Your web page
give a point to the web site, but the website give nothing to
yours. As a result the PR of the web site will increase, but
your web site's PageRank will go down.
Another way of link exchange's scam is to make your link hidden
from search engines' spiders. The link can be hidden by putting
it inside javascript, redirect it to a php or asp process page,
instead of plain 'a href' HTML code. Using CSS (cascading style
sheets) also can trick your eye, which make link appear to be
correct, but in fact it is redirected to another way around
before it go to your web site.
Meta Tag also can be use by selfish web masters to hide link.
Actually it is not hide link, but instruct the search engines'
spiders to ignore any link on the page. So the spiders will not
consider the link as a point of importance of other page. The
meta tag use for this action is "nofollow".
As a way of precaution to increase your link popularity (and
PageRank) by link exchange is you have to make sure:
1. The directory which the link is located is not restricted to
any spider (robot). On the web browser's address bar type
http://www.websitetocheck.com/robots.txt. Check the restricted
directory.
2. Always check the source code, make sure the link is directly
pointing to your web site by 'a href='http://www.yourwebsite.com'
3. Check those links in weekly or monthly basis, if the link
which is pointing to your web site is missing, delete their link
on your web site.
4. Check the meta tag of the page and try to find ' meta
name="robots" content="nofollow" '
