when writing file name is it better to use singular or plural?

 

I would personally go for abc-efg.htm
BTW your avatar looks good.

 

/abc-efg/abc-efg.htm ?

or
/abc/efg/

id go for /abc/efg/

 

domain.com/keyword1-keyword2/ but make sure you configure htaccess to add a trailing / to the url

 

I think this is best if you aim for the searchphrase "keyword1+keyword2"
but if you want to aim for keyword1 and besides that also on keyword2 i think keyword1/keyword2/ would be best right?

 

why? can you spell out the difference? what do you mean by configure htaaccess to add a trailing?

 

Mad4, been wondering about this lately but couldn't tell if it made a difference - do you know?

 

In addition, you can create any file with as many keywords as you want and no extension just making your .htaccess recognize its content as php or htm

 

Google struggles with canonicalisation so it treats site.com/page as a different page to site.com/page/

You can use htaccess to add a trailing slash.
