[SEF urls] better end with slash or with .HTML?

In your opinion, is it better for an url to end with a trailing slash or with an .html or .php extension?

I mean, which is better for indexing
www.mysite.com/A-Second-Life-for-Your-Ad-Campaigns/

or

www.mysite.com/A-Second-Life-for-Your-Ad-Campaigns.htm


Please discuss

 

1) I would use all lowercase

2) I've been using .html in the end.. But I see many people ending in / ... I think it's up to you

 

lower case is a must, I know I just copypasted a real url from a site

 

using slash, means, Your website wont work when user types the url without slash, So.,, you must 301 redirect domain.com/1 to domain.com/1/

 

That's not true. I don't redirect my domain.com/ and it works fine with or without the slash.

I don't think it makes much difference whether or not to use the slash, but since using it doesn't hurt and can help in some situations, I would use it...

 

As long as I have the choice I would go with the .html page

Don't know why.

 

It's just a technical difference and has no impact on SEO.

 

Yes, it does not really matter. I guess "HTM"/"HTML" extensions are stripped in the evaluation process.

 

www.mysite.com/A-Second-Life-for-Your-Ad-Campaigns/
and
www.mysite.com/A-Second-Life-for-Your-Ad-Campaigns

are different url's

It's best, for inbound links reasons, to use:

www.mysite.com/A-Second-Life-for-Your-Ad-Campaigns.html

or something of the sort (as to avoid canonicalization issues)

all things being equal though, there is no difference for seo reasons (other than above).

 

That's a good Point! Inbound Links wouldn't spread!
