On Flippa guys sell website with amazing traffic about 5000-2000 uniques/day, which they got for a couple of month since created website, but how they doing this? Their websites have small amount of backlinks. What is the secret?
Keyword research is the main reason behind this, there are some keywords which are easy to rank but still brings thousands of visitors daily!
Because the site they have information that is appropriate as to what is needed by many people in need, so the site can bring in more visitors
Did they mention most of those traffics came from organic search results? That's advertisement is teasing for newbies but sounds like cheating...
There may be many reasons like... 1. have used black hat seo strategies... 2. very good keyword research... 3. very good marketing campaign.. 4. fake traffic proof
As they have said and I seconded most of them are FAKE!.. There is no instant you must work hard to reach a good SERP with great niche for great traffic!
