Normally I'd agree with much of the advice given here, but for
this particular case, I'm going to disagree.
Why do I disagree? Because there is a much simpler, yet deeper issue with this site than any amount of SEO will be able to solve.
And with that, I impart another lesson for the newcomers to this board. Aren't you all lucky I'm here? Sure you are.

So here goes...
What I'd like everyone to do is follow these steps:
1) Visit seokumar's Investigator's Toolkit homepage (
http://www.investigatorstoolkit.com).
2) Click the "Instant Purchase" button (as I did.) You'll be redirected to this link:
https://www.plimus.com/jsp/buynow.js...actId=1633663&referrer=saurabh
The key to this is the referrer portion, which is a sign that our friend is affiliate marketing. There is nothing wrong with affiliate marketing in and of itself if done correctly...but this isn't it. This is nothing more than a mini-site with the sole purpose of promoting the eDetective software (
www.eDetective.com for those who want to go look and see the original.)
Why is this so important in terms of SEO and marketing? Important lesson in red coming:
seokumar hasn't built anything unique or original, nor has he bothered to put in any more than a token effort at best in an effort to get rich quick.
Search engines have caught onto this, as have a good number of us who have a bit of net experience (and I do have a little bit myself.) And our friend can automate his link building, exchange links, create doorway pages, and pull all sorts of silly little stunts to his heart's content and it won't make a bit of difference, because his site offers nothing.
In other words, seokumar, take your site and either improve on it greatly or stop wasting your time and move on to something you're willing to put more than 3-4 hours' worth of effort into.
