@Rongi brings up a execlent point when it comes to SEO.
It may sound super beat up, but grindstone once said it
SEO is not hard. Google ranks sites #1. Analyze them. Lots of them. Find
commonalities. Exploit. Rinse and repeat. Don't be lazy and stupid.
It may seem really tough, but I have succesfully done it in many niches.
The thing is by copying you wont get to number 1. That's where you need some Blue Hat Tactics but you will get to top 10.
What's crazy is if you do enough niches, what works to get you top 10 in one niche, might be enough to move you to top 5 in another, etc.
