Most SEO professionals know that link building is an important part of any SEO strategy. It’s also fairly well known that building links from relevant websites is better than links from irrelevant websites.
For example, if you’re in the SEO industry, links from other SEO websites would be better for your rankings than links from websites that sell ice cream. Because of this, many people (SEO experts or otherwise) actively engage in link building techniques on the Internet.
One link building technique is the laborious, but worthwhile, tactic of visiting blogs and forums and making posts, using your website in your signature or website field. A good quality comment left on a relevant website, linking back to your website, can do wonders for your rankings and also great things for your reputation online. Making insightful comments can enhance your reputation as an expert in your field.
However, posting spam comments on a number of blogs can harm your reputation in the field. Some SEO companies utilise black hat tactics whereby the same comments are left on websites as part of a link building tactic. These comments have little or no relevance to the actual post, and they are the same on every single website. Their purpose is to act as a link back to the client, but all they do is raise awareness to the use of spam tactics.

Thanks for the very helpful information about SEO. I enjoyed reading your article and I found it very interesting. Staying tuned for more.
At first glance, it seems like a relevant comment. It uses the term SEO and it has been posted on an SEO blog. However, the non specific nature of the comment should set the alarm bells ringing.
You can test if this is a spam comment by Googling a section of the comment, to see if it exists elsewhere. You’ll find that it does, and it has been posted on a great many websites, many of them SEO websites.
Searchenginejournal.com for example has published this very same comment on one of its blogs.
When managing your own blog, be very wary of spam comments such as this. They will harm the credibility of your blog and, at best, they’re duplicate content.
When engaging in link building tactics, do not under any circumstances paste the same comment on multiple websites such as this, or use any SEO services that do it for you.
