I would say start with the basics. Do not look for quick wins. A common mistake is trying to do too many methods at once. Select one aproach learn how it works nd be patient. Consistency nd testing usually yield better results than trying different strattegies all the time.
In my opinion, an error made by novices is looking for a winning strategy before learning to analyze outcomes. The world of SEO is rife with techniques that sometimes work but often do not. By being able to assess why the pages appear in the SERP and testing your own assumptions rather than just repeating another , you will develop faster .
The biggest error made by new comers is following techniques without knowing how to explain the concepts underlying them.
Beginners usually concentrate on looking for ways to take shortcuts, but knowing why things work is more important.
What I would really concentrate on is how to evaluate the risks and rewards of using certain tactics rather than simply whether they works in terms of ranking pages. in most cases, if an approach helps you quickly improve your position but cannot be used for diagnuosis later, it would probably be worth learning from.
The greatest error made by people who believe in the effectiveness of black hat SEO is the way they view it. While black hat SEO should treated as a science of testing, they treat it as a series of tactics that may be successful or not depending on situations . For a time , a strategy that works great in one case may totally fail in another because the sites, competitors and other factors are different.
Another thing that i would suggest is learning how to read the results of an not successful test as well as a successful one. There are certain tactics that seems to work for several weeks but fail completely bcz you do not know what exactly caused the shift in variables. This kind of skill may be more important than learning some black hat techniqiues.
