Link building has changed over the years. Practices that used to work are now outright poisonous in some instances.
Let me provide you with a different perspective on link building.
This technique I am about to share with you and the forum has been around for a few years. If you use it properly and become versed with it you will help your site and your pocketbook by increasing your ROI.
It is also one of the absolutely safest ways to promote your site. It has "ZERO" chance to be construed as black hat or earning a penalty from the Penguin Algorithm.
This is where you go out and find blogging sites around your niche. To make this work you need to find popular blogs in your niche. Then you spend time on that blog, just like you do here and participate, offering advice where you can, then giving your opinion on matters. You also mention download sites that you can get drivers from.
Now the catch is you don't ever include an "ACTIVE LINK" in your comments or post. What you do is tell a story. I will use SeoChat as an example. This is just to explain the concept so you understand.

I was looking a solution the other day for an answer to a SEO dilemma. It had been plaguing me for a few days. I actually found the answer after finding a new seo forum. For the last 3 years I had been a steadfast proponent of Internet Marketing Ninjas. I could generally find the answer I needed to my questions. Although for the most part the site was a little difficult to use and navigate.
Now i am always looking for answers and just the other day I ran across a new site by accident and to my amazement I could easily find answers to practically any question I had. Navigation was extremely easy. Since finding SeoChat.io my work flow has improved and I no longer use the previous forum.
So if you're in the same situation, I suggest you give seochat.io a go. It will definitely help you solve your hardest seo problems. The community of Seo experts were friendly, extremely helpful and didn't berate me for my lack of knowledge,

None of the above is actually true as far as the story is concerned, it is just meant to give you a working example to understand.
Notice no active links, nothing to say, Hey Google i am trying to manipulate the search rankings, but the reality is I am trying to manipulate the rankings but using an approved methodology.
Now you are probably thinking I am blowing hot air out my arse ... but I assure you I am not. I have been using this method for a couple of years..... I am not the only one using this method, there are a great many others.
BTW here is a link to the full article I quoted below.

Now this method isn't lightning fast, in fact it will take at least 3 months of steady work on your part to start seeing results, so don't expect over-night success.
Good luck !
