SPAM Comments (have a link in the content of comments) do not affect SEO

Comments are very valuable for all people in the world in order to get an endorsement that can be uplifting or as a reference so you can correct yourself from shortages. However you might feel very annoyed when someone commented, but the comments are detected as comment spam. many of the bloggers who say that, comment spam will affect the SEO of your blog. Maybe a little confusing why the comment spam can affect the SEO (Search Engine Optimization). Let us discuss a little about the comment spam that could affect SEO below.

Many of the bloggers who know that the outbound link is very bad for the development of SEO on your blog (I strongly agree). Usually the spam comments are always identified with the comments that inserting a link in a comment. Now insertion of links that do make the bloggers think that it is one that includes outbound links (links out). It is true that the link posted it leads out of your blog, but I think the comments without having any links within the content of comments, including comments that have outbound links.

Why do I say comments that do not have a link in the comment as an outbound link?

Because every comment is usually insert the name and URL. I think this is also an outbound link, because the links are inserted on the commentator's name is a link that leads out of your blog. But the decision is yours as a moderator, to decide appropriate or not comment for publication.

So, whether bad or inappropriate comments that have links on the content of the comments are considered as comment spam?

I think not, because every comment made ​​in response to an article / post you publish. Google also does not prohibit the use of links in the content of your blog comments, because there are some HTML tags that Google agreed to. Here's an article that I got from Google.

Note : Please delete comments that only insert a link without responding to the article that you write. But the decision is always in your hand.

Preventing Unwanted Comments and Comment Spam

Blogger has several built-in measures for dealing with comment spam and other associated dastardly behavior.

1.   Only five html tags are accepted:

<a> (for making links)
<strong> and <b> (for making text bold)
<em> and <i> (for making text italicicized)

2.   All links will automagically use the rel="nofollow" tag, so they'll receive no PageRank boost.

3.  You can choose to receive notification by email when new comments have been posted on your blog. This way, you can monitor them for spam and delete them when necessary.

4.   You can enable word verification for your comments. This will require an extra step in the commenting process, which will deter automated comment spamming systems.

5.   You can enable comment moderation, which will let you view new comments and approve or reject them before they appear on your blog.

From the articles I get from Google directly, we can learn that the use of links in a comment that is not prohibited. Because Google approve the use of html tags <a> inside the content of comments. If not approved by Google, so long as this comment box could not be filled by inserting a link in the content of comments. In addition to reducing the number of comments on your blog, Google recommends you to activate Word verification and Comment Moderation.

For what Word Verification is enabled ?

Of course, Word Verification is enabled to avoid comment spam. Word Verification typically used to avoid any comments from the robot, because comments from bots or spam bots comment (maybe that's his name) would just be a waste in your comment box.

Then for what the Comment Moderation?

Certainly, comment moderation will involve yourself as a moderator comment. You are here acting as a moderator who has the right to choose the comments left on your blog, and you are entitled to approve or delete the comment before comments are published.

Then why do I think that comment spam does not affect SEO?

It's easy to explain. Here's the logic, you know that the outbound link is very bad for SEO. but the fact that Google agreed <a> html tags (html tags for links) to be inserted into the contents of  comments, but you think that comment spam because it includes outbound links. Though all the comments that insert a link, All links Will automaically use the rel = "nofollow" tag, so they'll receive no PageRank boost. So no harm is not, after all the inserted links are nofollow links.

In addition, there may be amongst you who think that comment spam is a comment that is like dropping your blog. Usually such an insulting comment on your blog, but if that comment affect your SEO? Of course not. What is the relationship humiliation comments with SEO? I think there is no connection at all. Comments that contain that are insulting or comments that want to drop your blog will only damage the reputation of your blog not affect the SEO of your blog. The proof there are some blogs that I frequently read and often get comments blasphemy (let's call it blogernas), but every day has a very large traffic. But if you are not pleased, you can delete the comment before it is published, because you are the moderator who has the right to choose an appropriate comment for publication. Once again there is a decision for publication comments is in yourself.

Ok just a few of my analysis about the comment spam to the effects of SEO, there may be some things wrong. But I still believe that, comments is not something that can affect good or bad SEO of your blog. Since your content is good or bad, all depending on the Search Engines to choose.
