As a webmaster, you are probably constantly inundated with spam comments for your posts. There are definitely ways to handle these comments, and to prevent them from actually being viewed on your site, or having unnatural links appear from disreputable sites. It does take some time and effort to ensure that you are only having true authors appear on your site, and only real comments. Make sure that you have things set up so that approval is necessary and no comments will appear without your explicit consent. When you get true comments, you can often get a quality link, which will help you with your SEO plan.
Here are three ways to check the comments that you receive on your blog posts to determine if they are spam comments, to help you avoid having garbage that you do not want end up visible to your visitors:
1. Check the authorship: When reviewing the comments that you get for your blog posts, check to see if the author used a real name. Fake names are often a sure sign of a spam comment. Even if the comment is legitimate, you still might want to avoid approving comments made by people using fake names. The comment section is a place where you can develop relationships with your visitors and readers, and knowing who you are dealing with and that they are who they say they are will add quality, much more than anonymous comments will.
2. Check the link: If the site link that is used by the author (most comments will come complete with a link, since most authors are seeking a link for their own site). If the site that is linked is one that is not relevant or related to the post or your site or your niche, then don’t bother publishing the comment. Irrelevant links are going to be seen as unnatural in the eyes of the search engine, and this will lead to problems when your site is crawled by the search engine spiders.
3. Consider the content: If the comment contains some generic comment like, “Thanks for posting,” without adding any additional comments, opinions, questions or other information, then it is very likely that it has simply been sent out as a type of fishing expedition, one that the author is using to try and gain links for their own site, rather than interact with you. The comments that you publish should be ones that are going to initiate further commentary by you, the author or other readers. Generic ones can be passed over.
If you are not able to set up your blog so that comments need to be approved before they are published, then you should find an internet marketing agency right away to make sure you get your settings properly aligned to filter these spam comments. Spam comments do nothing to help your SEO plan, and, in fact, they will cause harm to your search engine ranking and make your site look sloppy and unprofessional.
