IMO, keywords should come early on in the title, in most cases.
I agree, and that's what I always try to do.
For the description I would try to make it sound as natural as possible, but still do include the major kewyords throughout. This is your selling point to the reader. Do they click your listing or the next guys?
I agree with that, too. And it drives me crazy when my descriptions are normal sentences written for users and the stuff in the serps above me are just a bunch of keywords strung together. Makes me mad.
I think optimizing the descrition tag for the search engines should go hand-in-hand with optimizing it for the visitors. Don't force things if they won't make sense to the end user.
Agree with that also. thanks.
I did want to clarify for this purpose the keywords are product names. So if I have for the Title "Pretty Blue Round Widget blah blah blah" should I also start the META Desc. with "Pretty Blue Round Widget - sentence 1. sentence 2." or work that in elsewhere in the desc., or does it matter anymore? That "vary the title and description thing keeps sticking in the back of my mind, but does it apply here or only to a title and desc. that are both identical such as both being only "Pretty Blue Round Widget"?
