authority link rental from a site like CNN.com had a tracking code. Google and
Yahoo! thought www.site.com/?source=cnn was his home page.
Some search engines will usually use the highest PageRank URL as the canonical
URL for a given page. If that URL version does not have good anchor text from a
variety of websites, then you risk tanking your rankings if you link to a high-
ranking page using a tracking code.
Canonical URLs
As stated in the above section about links with tracking codes, search engines only
want to index one URL for each set of unique content. The ?www.-? version of a
domain is a subdomain of the root URL. Sometimes the contents are the same,
but they are not always on all sites.
It is in your best interest to 301 redirect the URL you are not using to point at the
in-use version of the URL. This way, you do not run into canonical URL and
duplicate content issues. It also will help unify your link popularity if Google is
unaware that both URLs are the same site and some people are linking to different
versions of the URL.
Make sure you know what your old .htaccess file is, read about modifying it, and
know what you are doing prior to modifying your .htaccess file. Always back up
your old .htaccess file before modifying it.
Renting PPC & Contextual Ads for SEO
While PPC ads run through ad servers, and thus do not aid your link popularity,
buying targeted ads can still help boost your exposure. If people find your site they
may be willing to link to it.
I buy over $2,000 worth of AdWords and AdSense ads each month for this site
because I know it will lead to sales that roughly pay for the ad cost, and I get
further mindshare and free links from the new readers out of the deal.
Linking Networks
Currently, I do not use any linking network to boost the rankings of my sites, but
there are a few innovative new linking networks that are worth mentioning.
Digital Point created a free cooperative advertising network where text links are
randomly rotated across thousands of sites in the network. The advertising
network does not focus on relevancy much yet, so currently it amounts to a big link
farm, but since it is so well-integrated into the web and spans so many sites, it is
rather powerful. Some search engines, such as Google, look at temporal effects of
linkage data and are not likely to place much trust on new rotating links. In a
Threadwatch post, Matt Cutts may have also hinted that they could use rotating
inbound and outbound links as a sign of a lack of quality and lower a site?s crawl
priority based on that.
