Need Perfect URLs

[Stryde]

I'm redesigning a site's structure from the ground up, and am having issues with the URLs. I'd love to have them be perfect, but kept finding conflicting advice online.

1. For my services blog, is it best to have it set up like www.example.com/services/keyword or 
www.example.com/keyword

There seems to be conflicting advice as to keep it short and keep the keyword as far to the left as possible, but also that including the word services would help with long tail phrases and site organization.

2. For my blog section, is it best to have it set up like 
www.example.com/blog/keyword    or
www.example.com/keyword    or
www.example.com/blog-post-title-with**-keyword**-in-it

It's similar to the first question, but also adds the question of including the entire post title in the URL or just the keyword.

Your help would be greatly appreciated!

Not sure on #2 because I don't have a blog on my site yet but I would think the answer to number one would be to have he keyword closest to left.  If you want you can also put the "services" afterward it seems if you wanted to get credit for that word too.

My two cents here are to not overoptimize urls just for ranking purposes, It's better to have kws in titles and h1-2 to help you rankings I'll choose the url structure based on how the choiche which will give you the highest control on them just for easy analytics study and future re-strucutration of the site. Also having a keyword may be good to have them bolded in serps so whichever choice you made may be good although I'll rely more on the shortest option which can give you both control and keywords in it.

You can't go wrong with the keywords in the URL's. But titles are very important too for sure.  I definitely recommend key words in titles if relevant and organized.
