I just finished reading Gerry McGovern's excellent book, Killer Web Content.
In it he recommends using hyphens rather than underscores to break up words in URLs for SEO purposes. This is because search engines don't recognize underscores as spaces and so run all the words together into an unintelligible jumble.
It struck me that given how technologically advanced search engines are supposed to be these days, surely they have the ability to recognize an underscore as a space as easily as a hyphen?
Or have they just not got round to overcoming this particular obstacle?

Yeah, Underscores are really not recommended or recognized in terms of SEO purposes. I remember when I was starting to learn SEO, i really like to use underscores on urls.. Geezz.. I didn't know I'm doing wrong with that... Oh well, this is very good source of information... :)

SEO is more complicated than it often seems to be. Knowledge such as this is very helpful and useful.
I will definitely check back in the future because this website is a great source for useful information.
Thanks for the info.

It is definitely like that. The hyphens are allowed in domain names so they would definitely work better in any web address than other symbols

I didn't know that for a fact, but I've always felt a bit ookie about underscores for some reason, so I just don't use them. Thanks for the info!

I've also always used hyphens rather than underscores when naming web pages as part of a URL. Using hyphens not only influences better results on SERPs but also enhances readability.
My issue is that underscores preceded hyphens as the natural replacement of a space long before SEO and Google interjected with new standards, meaning the web addresses may not always make sense. What I mean is that we may soon be oblivious as to whether a word is properly hyphenated or is simply a space replacement. E.g:
www.well-known-places.com
instead of
www.well-known_places.com
This seems like a backwards step in Internet Usability.

I avoid underscores mainly because if the text is a link that is underlined, the text appears to be spaced and the underscore is not seen. Many people don't understand that spaces in URLs are not allowed, and don't really think about it, thus the %20 that gets inserted. Many people have learned this by putting spaces in their file names and never giving it a second thought.

Search engines, the major ones anyway, don't care whether an underscore or a hyphen is used.
To see that they can recognize either without a problem, keep an eye on the text highlighted in the SERPs and sooner or later you will likely see just as many examples of words within underscored chunks being recognized as words separated by hyphens.
"To hyphen or not to hypen, is no longer the question." ;-)

"To hyphen or not to hypen, is no longer the question."
well, that was esoteric nonsense from the first day. same with most SEO trends.
first learn how to build a search before trying manipulating its results. it's funny to see so many self-called SEO experts not even slightly understanding how the technical side of a search works (and they initiate stupid legends like the "underscore problem" above).

Having recently emabarked on a new seo campaign the pitfalls within seo are apparent. It seems all to easy to get it wrong but difficult to get it right! If you think seo is easy your probably doing the wrong things - or so I am led to believe.
Blogs like this can be a great source of information, keep up the good work guys.
