You should definitely listen to than man. He knows what is working and that is why all the SBI sites are so successful (at least for those that actually apply his tips, lol). Not going to tell you what to do, but try other free sources before spending on Adwords. I actually think ADW is great for landing pages, where you are selling something that will make you a nice amount of money, but it is hard to get them to work if you are not an expert. Actually what I am trying to say is that if you are trying to just get more traffic, blog commenting would be much better. OK, all the free resources need time, but they can often convert better than others. PreSell and SEO the SBI way are a guarantee of a successful site (talking from experience here). Thanks for the comment and waiting for more feedback :)
You are right. Actually, it is the same with answer site, I mean the same strategy. But you need to be smart using them, you have to answer the question and point them to a link. But with people's short attention spans, they are satisfied with what ever answer you give them and they don't go exploring links so much. Again it does depend on the niche and the type of question. I like that you tracked what converts on your blog, because that is the best thing to do to see what to focus your energy on. Thanks so much for the comment, Bryan.
Forum comments work much the same way as blog comments, except you tend to lack the base post from which to play off. Instead, you need to invest some time into getting to know the culture of the forum, the prominent users, the rules, and the discussion flow. If people generally post one sentence at a time, adding a 3,000 word post will be excessive and may be mocked. If people tend to post lengthy discussions, short posts may have a negative effect. And, like Reddit, some sites may be very rabid about enforcing no advertising.
This is the number of views that you can test each month on your website.It's up to you how you choose to use them, either by allocating all the views to one test or to multiple test, either on one page or on multiple pages. If you have selected the 10.000 tested views plan and you run an experiment on your category page which is viewed 7000 times per month, then at the end of the month 7000 is what you'll be counted as tested views quota.
