SEO Question on Inner URLs! Best Practice

[JanWalker]

Hi,

Got a question in relation to best practice when you are targeting two keywords on a page - i.e they are almost identically related but differently searched terms - so want to include both in the url.

So let's use the example dog accessories and dog supplies.....maybe not best example but all I can think of right now..

so which of below 4 would be the best and most optimal for search engines/users?
mywebsite.com/dog-accessories-and-supplies
mywebsite.com/dog-accessories-supplies
mywebsite.com/dog-accessories-and-dog-supplies
mywebsite.com/dog-accessories-dog-supplies

Also 2 more questions:
is it better to have the more favored keyword closer o the slash?
and after you create a new 301 redirect how long does it tack google to pick up and when can you start link building to it? i.e do u need to wait until after indexation or can you start straight away?

Look forward to your responses!

maybe

>> "and after you create a new 301 redirect how long does it tack google to pick up "

depends on the website.

Could be seconds or months. They don't kill them all at the same time. For example if you 301 10,000 pages, then the may only do a few hundred per day.
