Well, Greatly described Points. But I agree with most of your points.

Recently Google become more intelligent with quality update and now, they they know, what content is all about, so they know, exactly, where to rank our article, depending on it’s quality.

So, Keyword Density is out of the window these days, Instead, we can just use LSI keywords for better ranking.

Also Meta tags like Meta description is not that important, like it was few years ago, now, Google can pick any word or phrase from article depending on users query.

But I do agree that, using Headings Tags, Image Alt Tags and internal Linking is very important.

So, Overall, having a nice URL structure, Authority Outbound Links, proper Title, can do the Job easily.

Correct me, If I am wrong?

Good addition, thanks Lee!

Thanks man! Glad you like it. I guess if you are not working in this area on a daily basis, it can be hard to understand. But I guess that’s why they hire you in the first place.
Have a good one!
