It might not seem like it now, but one of these days you’re going to have to start worrying about comment spam.
Every blogger does.
It’s nasty stuff, left by even nastier people and it’s dangerous, dangerous for your, your visitors, and the entire blogosphere.
Holy canned Spam, Batman!
How can comment spam be dangerous?
1. What Is Comment Spam?
You’ll know comment spam when you see it.
The comment itself is usually only about three words long:
Nice post. Thanks!
There’s nothing to indicate the commentor even read your post and it’s usually accompanied by a link in the name box that leads to a questionable site.
These spammy bloggers hire people to leave hundreds of blog comments a day or they purchase software that lets them automatically submit their comments all day long.
2. It Damages Your Reputation
Imagine you’re a first-time visitor to some fancy blog and you decide you want to leave a comment.
Until, that is, you see all those links to Viagra and some EZCash Loans sites that have been left by hundreds of bloggers before you.
You’ll probably run away screaming and you definitely won’t go back.
Your readers trust you to monitor the links on your site.
They assume you’ve checked every single one of those links on their behalf.
When they finally do follow one of those links and end up on a spammer’s blog, they’re going to immediately spread the word that you’re not to be trusted, ever again.
3. It Damages Your Rankings
We’ve already seen that Google punishes blogs that link to poor-quality, shoddy sites.
If you’re using do-follow links for your commentors then you run the risk of having your site devalued.
Even if you’re using no-follow, Google still sees where those links are going and it’s a safe bet they’re eventually going to address this with another catastrophic algorithm change.
Many of those spammy comments include broken links, too, something which Google frowns upon.
Get enough of them and your blog may be severely penalized.
What makes this situation even worse is the fact that if your site drops in ranking another site rises to take your place – and it’s probably going to be one of these spammers who beat the system.
Unfortunately, if you let these links stand, your readers might actually follow that link.
Many of these spam sites include malicious malware that can harm the visitor’s computer.
Now, wouldn’t that help your online reputation when you send one of your readers to follow a link that ends up blowing up their computer?
4. It Damages The Blogosphere
As a blogger you should know this: If you’re not part of the solution you’re part of the problem.
Each time an unscrupulous blogger successfully gets his spammy links published in a comment somewhere he’s striking another blow against a reputable blogger who’s worked his butt off to provide quality content and a blog where people felt comfortable.
Those spammy comments scare away visitors and it’s your responsibility as the host of your blog, to control comment spam as much as humanly possible.
