What are unnatural
links?
Any links intended
to manipulate PageRank or a site's ranking in Google search results may be
considered part of a link scheme and a violation of Google’s Webmaster
Guidelines
Examples of
unnatural link patterns which can negatively impact a keywords rankings in the
search engine results page:
- Buying or selling links that pass
     PageRank. This includes exchanging money for links, or posts that contain
     links; exchanging goods or services for links; or sending someone a “free”
     product in exchange for them writing about it and including a link.
 - Excessive link exchanges ("Link to
     me and I'll link to you") or partner pages exclusively for the sake
     of cross-linking
 - Large-scale article marketing or guest
     posting campaigns with keyword-rich anchor text links
 - Using automated programs or services to create links to your site
 
Additionally,
creating links that weren’t editorially placed or vouched for by the site’s
owner on a page, otherwise known as unnatural links, can be considered a violation
of our guidelines. Here are a few common examples of unnatural links that
violate our guidelines:
- Text advertisements that pass PageRank
 - Advertorials or native advertising
     where payment is received for articles that include links that pass
     PageRank
 - Links with optimized anchor text in articles or press
     releases distributed on other sites. For example:
There are many wedding rings on the market. If you want to have a wedding, you will have to pick the best ring. You will also need to buy flowers and a wedding dress. - Low-quality directory or bookmark site
     links
 - Links embedded in widgets that are
     distributed across various sites, for example:
 
Visitors to this page: 1,472 car insurance
·       
Widely
distributed links in the footers of various sites
·       
Forum comments with optimized
links in the post or signature, for example:
Thanks, that’s great info!
- Paul
paul’s pizza san diego pizza best pizza san diego
Thanks, that’s great info!
- Paul
paul’s pizza san diego pizza best pizza san diego
The
best way to get other sites to create high-quality, relevant links to yours is
to create unique, relevant content that can naturally gain popularity in the
Internet community. Creating good content pays off: Links are usually editorial
votes given by choice, and the more useful content you have, the greater the
chances someone else will find that content valuable to their readers and link
to it.
