According to econsultancy.com which was published on Jan. 21, in his latest announcement regarding Google's policing of the internet, Matt Cutts, the head of Google's Webspam team, declared guest blogging dead as a linkbuilding tactic. “So stick a fork in it, guest blogging is done. It’s just gotten too spammy. In general, I wouldn’t recommend accepting a guest blog post unless you are willing to vouch for someone personally or know them well. Likewise, I wouldn’t recommend relying on guest posting, guest blogging sites or guest blogging as a linkbuilding strategy,” he stressed.
Unfortunately, guest blogging for search engine optimization has been hammered lately because of its use as a link-building tactic. Google's policies in the never-ending battle against spam can be irritating at times, especially for Website owners that provide value to their users. Specifically, in this case, bloggers that accept guest posts as a means of adding variety and a different point of view to their blog. Google realizes this and encourages it, but you have to wonder if you might inadvertently be punished in the crackdown, even if your intentions are good.
Many blogs, particularly those with a relatively small writing team, invite guest bloggers to post on their site as a means of providing their readers with more quality content. In light of these recent developments, it would be wise for these sites not to accept a high volume of guest posts, especially low quality content. Content that is not relevant to the purpose of your site and does not add any real value will most likely be seen as spam.
Blog owners should be meticulous as to who they accept content from. Read the post from the users’ point of view and ask yourself if the author seems genuine, are they perceived as experts in your niche or field? – do they have a legitimate following? Be a little more cautious over what you accept in future. Google realizes some sites rely on point and counterpoint opinions. Cutts pointed out that their new policy was not aimed at 'multi-author blogs.' He does not want to 'throw the baby out with the bathwater,' he clarified.
The future of quality guest blogging will most likely be judged by the relevance of the content to the recipient link and on the merit of the site that posts the guest blog. If the volume of guest blogging is high and used as a link building tactic, your blog will most likely to be seen as spam, particularly if all your links are to commercial landing pages.
