Google has issued a reminder to publishers about links posted on other sites for a purpose of building inbound links.
In large-scale article campaigns, the company says, to have seen an increase in spammy links stuffed in these types of articles oftenly referred to as "contributor posts, guest posts, partner posts, or syndicated posts," which are generally written by, or are in the name of a website, but published on a different site.
Google is not against these types of articles, when they are informative, however, the violation happens, "when the main intent of distributing content is to build links in a large-scale back to authors' site," which is strictly prohibited under Google's guidelines on link schemes. This act of publishing articles stuffed with spammy links could affect the perceived quality of a site and its search ranking, google said.
Google encourages people to wrtie guest posts or syndicated posts which "inform users, educate another site's audience or bring awareness to your cause or company."
Further, the company explains the factors that indicate when an article is in violation of these guideline said,
- Stuffing keyword-rich links to your site in your articles
- Having the articles published across many different sites; alternatively, having a large number of articles on a few large, different sites
- Using or hiring article writers that aren't knowledgeable about the topics they're writing on
- Using the same or similar content across these articles; alternatively, duplicating the full content of articles found on your own site (in which case use of rel="canonical", in addition to rel="nofollow", is advised)
And, thus, encourages site owners accepting such articles should vigilantly vet them, and use rel="nofollow" attribute on any links with questionalbe inent.
Not only publishers, but Google will also take action on websites involved in creating the content made for links. Also, webmasters who are aggressively or repeatedly harassed for "Post my article!" requests, are encouraged to report via spam report form, says google.
Lastly, Google also advises site owener those who are involved in link farming in a form of endorsement, should include "nofollow" and put best of their efforts on improving site's content.
