Google warns webmasters against building links through large scales article submission campaigns and guest blog posts. According to the official Google Webmaster Central blog, if an article is written and submitted to different websites with an intent to build links than to educate/inform actual readers, it may cause Google to suspect such websites and the website owners to lose ranking in Google search engine result page.
However, it is also made clear that building link is can be fine but the very intent of writing an article and submitting them the different sites to get merely backlinks is a bad SEO practice.
The articles which are written and submitted solely to get back links should be avoided. Here are some of the scenario which Google specifically pointed out –
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
According to Google, webmasters should focus on creating good and original quality contents and should not have a large number of links coming from article sites or the same sites. However, if the same content is to published from different sources, the webmaster must use rel= canonical and rel= nofollow.
