Using commas in the title tag?

[Audiohype]

Is there a disadvantage/advantage to using commas to separate words in the title tag. Which will be more effective as a title tag: "keyword1 keyword2 - Brand" OR "keyword1, keyword2 - Brand"?

Anyone has any thoughts as far as "-" as a way to designate keyword string as in funny-greeting-cards vs. funny greeting cards,....

Like Barry, I've not tested this conclusively; however, I'd be very surprised if natural comma usage has much if any negative effect.

In this instance you'd probably be better off with a comma splitting the two (very similar) keywords just for the human factor: "cheap books free books" looks spammy and is likely to put people (and potentially Google, depending on how far you take it) off.

I see.

Well, I certainly used to put a few keywords in titles using commas assuming it acted as a separator, however (and again anecdotally) I now write (as does everybody I'm comparing myself to) titles in the format "Cheap Books and Free Books".

Stick 'poker' into Google and look at everybody's titles. A few years back that would have looked like 'Poker, Online Poker, Texas Holdem | PokerSite" where as now it's "Poker and Online Poker including Texas Holdem at PokerSite".

However, stick 'travel' into Google and you'll see everybody still using commas.

So, as I say, I can't think how it would adversely effect you but I think with Google trying to extract meaning from people's searches that, in the long term, more natural sentences over a list of keywords would serve you better.

Thanks for your quick response Barry. I understand what you are saying, but I think I am coming at it more from a point of the search engines figuring out the difference between keywords.

Say for example the title tag was "cheap books free books" would the search engines be able to figure out that there should be two sets of keywords there as opposed to four inidividual words. Do commas help to define this?

How do search engines treat the comma?

Hmm, I've not tested conclusively but I can't think how a comma would adversely effect you. However, anecdotally, I've seen lots of sites move away from commas and pipes in titles so I'd have to assume that something was up.

I don't think stop words are being treated the same as the used to be with Google trying to figure out intent more and more, plus I'm not a huge fan of special characters (not that a comma is that special) in the title so unless it looked ridiculous I'd consider not using it.
