Do We Have Opinions or Do We Have Facts?

I have been wondering about this a little bit lately, as it has come up more than once.

Everyone has an opininon, and that is perfectly fine, but there are some things that I think of as fact, not opinion. For the most part, I think SEO should be one of them.

When I started here, I really knew nothing about SEO at all, and I was a bit concerned about my ability to learn it because it seemd that different people had different view on what was effective. I resolved myself to simpl yfollow what is presented in the lessons here. That seems the most logical thing. I mean, I pay to learn this stuff here, right? So I should be following these lessons.And frankly, I trust the information presented here.

So it seems strange to me that there should be conflicting views on SEO. Shouldn't it be facts more than anything else?

As I have written a couple of times, I am now being paid to do blogs for various sites. The company that I do this for provides me with topics, as wel as keywords from the SEO company they work with. But some of the keywords and the things they present to me don't match up with what I am learning here.

I keep looking at it the same way I would if someone said "Well, in my opinion, 2+2 equals 6."

How can you have an opinion on that?

Well, my opinion is that the lessons here at Wealthy Affiliate offer the best information, and so that is what I am going to follow. To me, something works, or it does not. There really isn't too much room for opinions.

What do you all think?
