What made this project stand out is possibly that we leveraged every possible traffic source.<p>For example the #1 person in the industry relied purely on SEO traffic while we attracted traffic through a massive combination of traffic channels.<p>Another important thing was that we produced content that was hosted by 90% of our competitors, so in the end most of our competition were indirectly promoting our project.<p>As you scale you reach a point of maximum value. After that if you want to acquire more users you need to drop your margins, this might be good in the short run to block out competitors that bid on your traffic but our choice was to get the maximum value out of our traffic in PPC channels in order to invest into longterm sources.
