to other web sites can hurt your
rankings if you link to the wrong
web sites. Links to web spammers
or "bad neighborhoods" on the
web can have a negative effect
on your rankings on Google and
other search engines.
A Google official has recently commented on bad neighborhood links and how they affect your web site rankings on Google.
What are bad neighborhood links?
It seems that Google doesn't like the following type of web sites:
- free for all links pages (FFA)
- link farms (automated linking schemes with lots of unrelated links)
- known web spammers
Linking to that type of site can have a negative effect on your Google rankings.
Is there an official Google statement about bad neighborhood links?
In a discussion in a webmaster forum, Google's Adam Lasnik has recently clarified what Google looks for in regards to bad neighborhood penalties:
- There is no relation between outbound links and Google's supplemental index.
"It’s unlikely that your
outbound linking is causing your pages
to be listed in the supplemental, rather
than main index."
- Google looks for bad neighborhood linking patterns
"Also, be assured that we’re not looking to penalize folks for a 'bad'
link here and there. Rather, our algorithms are tuned to look for patterns of
'egregious' linking behavior… both on individual sites and in the aggregate."
- You should check the links on your web site
"It's certainly in your users' interest that you regularly audit outgoing
links on your site (especially prominent ones) to ensure that you're not losing
folks' trust by sending them to inappropriate places or 404 pages.
Sure, it's great to keep Google happy, but it's usually more important
(long term) to have your users be return visitors."
What does this mean to your web site?
Google looks for linking patterns. That means that it probably won't hurt your site if you link to a bad web site by mistake. Use a tool like ARELIS to find good related web sites with which you can exchange links.
Many links to 404 error pages might cause ranking problems. For that reason, it's a good idea to check the links on your web site every now and then.
