It was rather to boost the incoming links to the main sales page by giving it loads of incoming links with very specific targeted keywords.
Now, getting results on that could take some time - My estimation is 2 to 4 weeks to see a real trend - Faster if I am lucky.
So far, I can see 2 side results:
----------------------------------
Traffic to individual blog posts does actually happen!
This is unexpected because I did not think that individual blog posts would be able to rank high so fast - That's good and it might be the main avenue to explore in the future.
----------------------------------
Potential traffic to main sales page coming from clickthroughs in blog posts rather than SE high ranking results.
That's another unexpedcted possible result - Not showing up yet - But could happen if traffic to blogs keeps increasing.
There is a key challenge associated with that - I'll check this in another post...
