Wow.... if you can buy Keyword.com I would grab it and redirect my current site to it.  The only reason I would not do that is if my current site had enormous branding value or was much broader in products and services than that keyword.

Keyword domains rank a little easier for exact match queries and my experience says that they have a slightly better conversion rate than most other domains.

Your original question... if you buy and redirect would it help?.... Yes, the link value of the site would transfer to the page that was the target of the redirect.

One problem with "building" links is that the more of them you acquire the harder they are to get.

Lots and lots of people ask this question... but think about it....

If I answered... "Fifty links is too many.".....   and you listened.....

.... but all of the websites on the first page of Google for your keyword were naturally earning 200 per week.... you could work forever and never make first page.

You need information about relative link velocity and link quality.

It is possible that you and three other people working would never be able to create enough links.

Thomasnet is a large site with a nice, but not overwhelming number of links.

Also, a lot of their competition is in naive markets where they compete against much smaller sites.  Although Thomasnet is not a major "powerhouse" they do have a nice number of links and that gives them enough authority to be a strong competitor in the naive and smaller markets.

What are good sources to buy traffic and video views?

If you want numbers then I don't think that there are any good sources.  However, if you are promoting to a specific audience then try Adwords.

Most SEOs don't recommend buying traffic... instead they recommend setting a goal of who you want to target and what you want them to do when they arrive at the site - then defining a traffic source to accomplish that goal.  Possible traffic sources might be Adwords, banner ads on specific sites, etc. or it could be as radical as buying a successful website.

Some term variants like this convert a lot better than others. My money is on "covers" - but I could be wrong.

So I would use the term where (traffic * conversion rate) will be highest.

If you don't have tracking to get a conversion rate you can get some data with Adwords testing.

This is a really good answer. Accurate, complete, very generous. Nice.

You were asking the wrong question.... but PeterM22 gave a great answer.

I'd do what he says and forget about Options 1 2 and 3.
