A few days ago Duane Forrester, the Senior Product Manager and public face of Bing, published an article on the Bing Webmaster Blog discussing spam link building.
He gives four specific examples of how to not build inbound links.
Blind Email Requests
Now every webmaster in the world probably gets at least a couple of these every week, you know the type of email, it will mention how much they love your website and that they will give you a link in return from another website. In the email they don’t usually include real trustworthy contact details, they don’t usually include their name and it will have come from a Gmail or Hotmail address or similar.
Its usually fairly obvious that they have never even looked at your site, in fact Matt Cutts and Duane Forrester have both given examples in the past of these link request being sent to Google and Bing, duh.
If you do insist on emailing webmasters to request a link be genuine and offer something of actual value, like a well written piece of valuable content, but the success rate will be so low you are probably better off spending your time doing something more productive.
Blog & Forum Commenting
No matter how many times both Bing and Google say that links in blog and forum comments carry no weight at all with regard to SEO there are still many so called SEO companies out there that include these activities in their descriptions of what they do for link building. So if you are contemplating using a SEO agency that includes this sort of spammy link building within their services I would suggest you forget about them and move on.
All you are going to achieve from this kind of activity is to annoy the blog owners and get yourself banned from participating on the forums and as a blog owner that gets around 50 spam comments a week I can definitely confirm it is very annoying.
Link Injection
This is a technique that has been popular with the spammers for a long time and the target is usually WordPress blogs or similar. It is usually an automated process that hacks into a WordPress blog and insets links into the site without your knowledge, you’ll never see the link as its hidden in the code but search engine crawlers can see them. Its fairly easy to fix though, just make sure you always have the latest version of WordPress installed as it will have patches to block the back doors that the spammers use.
Guest Blogging
This activity sits on both sides of the spam line. There are many legitimate blogs and guest bloggers it all comes down to intent really. If the blog itself is full of guest posts and seems to exist purely for that and the posts themselves cover a wide range of topics then its probably going to be viewed as spam, if you’re creating guest posts and publishing them on these sorts of blogs with the sole intent of getting a link then that’s most likely going to be viewed as spam. However if you write a genuinely useful post that offers value to the blog its being published on and you’re doing it for traffic and brand exposure then that’s good. Also any links you do get from it will be viewed in a much better light, so by all means guest blog but don’t do it for SEO.
