I have been reviewing in my head the "rules" for title tag success and a question popped into the vast empty recess where my brain would have been.....had it been present. I wondered to myself if using correct english , or even having a comprehesible (for humans) title tag is important.
For Instance I know a title tag like the following is strictly verbotten
"We sell blue, red, purple, green, yellow, orange and chartruese bicycles."
too many commas.
If I was trying to keyword for each color bike and I made the following title tag:
We Sell blue red purple green yellow orange and chartruese bicycles."
Would it violate any SEO rules or be black hat in anyway?
I realize for the viewer it's awful but I was wondering from a pure SEO standpoint.
