Characters in URL

From SEO's point of view, which is better and why ?

1) my-url.htm
2)my_url.htm
3) my+url.htm

Thanks

 

I think first one is better and mostly people us it also.

 

the first one of course... It is easier to type and mostly used combination...

 

yeah the 1st one .... no doubt about it

 

1st One is better
bcoz easy to write and easy to spell !!!

other are sumwhat diff

 

first url is the better option.

 

thanks for your valuable comments.

 

The first one is good.

 

why not second one dear

 

For SEO purposes, probably the best is the first example: my-url.html,
But overall IMO the better choice is: myUrl.html
Is easier to type, also the extension is more accurate with .html, although doesn't matter for SEO purposes.

 

The first one is a very good from SEO point of view...

 

I suggest you should use the first one

 

I recommend dashes or underscores for words in urls.

1st is better and almost webmaster (and me) use this way

but SEs like 2nd

 

First or second either one is good. Although first one is more common pattern to use. Third one got a special character +, which is not good idea.
