While sorting through some comment spam today I found that one UK printing company had been dropping spam comments on my blog.
This sort of behaviour always strikes me as strange because surely any SEO company knows that links from blog comments are worthless?
My blog uses nofollow in the comments links but I’m quite sure that Google devalues blog comments links even if they don’t use nofollow.
This started me thinking about all the other SEO strategies that are almost useless but that are still widely practised around the world:
- Mass directory submission
- Bulk article submission
- Forum signature links
- Comment spam
- Link exchange requests
Of course sometimes these techniques *might* give some results but the way that they are generally approached makes the chance of any ranking improvement almost zero.
Why does it seem to take so long for people to realise that these methods are no longer working?
