Removing a keyword in the title. will it hurt?

Did you even bother to read what he said? He doesn't want to rank for the term. The visitors he'll lose from dropping that term won't matter one iota to him, especially when you consider the gains he'll be getting from a potentially higher ranking from that keyword not diluting the keywords he IS targeting.

 

I strongly suggest you read this article by Chris Beasley then:

I don't know what you're getting at here. I haven't seen anybody in this thread selling pharma or penis pills, and every niche needs traffic. Personally, I run content sites. If you don't need lots of visitors, that's great, but then stop asking everyone how to improve your rankings.
I find the implication insulting and you might be nicer to the people who are trying to help you with elementary SEO.

@Dan: I've seen that info and tend to agree with it, but that doesn't mean long titles are inherently bad. A keyword density of 5% for a two word standard phrase would be a forty word title. That's obviously too long and empty. But a twelve word title with four layered keyword groups can be pretty effective, as my tests have shown.

I do believe that the title tag is valuable real estate in term of SEO, and should therefore be used to optimize for multiple phrases. I am aware this goes against conventional wisdom, but the idea that your first keywords would be less effective because secondary keywords follow them runs counter to logic.
It's a fine hair I'm slicing but I hope you can apppreciate the distinction.

 

I think the words that dmitrimarkine were citing were just being used as examples, nothing more. I've even done that in the past (though I've went out of my way to explicitly state they were examples, nothing more).

As for me, I prefer to have my titles' keywords focus on the terms being optimized for the page in question - and to keep my titles short, sweet and to the point.
