Viral Marketing?

I got an email this morning from Katherine Poll of Digeus Software the exact text of which is below. Now as my early blogs will attest, I do have an interest in the way internet will work for business and marketing in particular. This is a cool approach which I have not seen before. Digeus are offering what should be a useful software item for screen capture and asking in return to have their product mentioned on my blog. Now is it the fact that it is on my blog that interests them? Well of course the answer is in the postscript. You must not change the text Screen Capture Software which under the covers links this phrase with the company Digeus Software. So what you ask? Well I just typed "Screen Capture Software" into google and I got heaps of results as one might expect. I browsed through the first 6 pages and could not find a link for Digeus Software. If my suspicions are correct then if Digeus are successful in getting this link into a large number of blogs, Google's search algorithm will obligingly push them up the list. Viral marketing? Let's hope not!

"May I ask you to place the link below to our Screen Capture Software anywhere on your blog? If you agree, please send me the link where you placed the link and I will present you with a license for free.

Here is the link:
