Been using blogger with pretty good success and would now like to extend my portfolio. any others that have given good results???
There are lots of plugins available for wordpress seo... E..g. All-in-seo pack.. So wordpress is the best.
As mentioned wordpress is by far the best - you'll also find some rather useful SEO plugins on the wordpress website (as suggested by MeetHere)...
I personally use blogger, although I've heard good things about this WP plug-in: http://www.authoritysitecenter.com/
wordpress needs a lot of tweaking to get it good for SEO - but an out of the box SEO'ed wordpress can be found by using Semiologic.
