Is there an easy way to sdearch for a list of blogs or sites that allow do-follow backlinks? I remember there used to be a way, but I forgot what it was now that I've been out of the industry for several years.
1) Buy Scrapebox 2) Harvest blogs with Scrapebox in your clients niches 3) Sort by PR (an option in Scrapebox) 4) Sort by Follow/nofollow (another option in Scrapebox) 5) Optionally remove URLs with higher than "XX"/"XXX" outbound links Once you've done this, you'll have a list of high PR, follow blog URLs to manually comment on.

If you can't afford Scrapebox then you can check manually.. However, you need to build natural links so considering some nofollow would be good idea.
It is very easy to find do-follow blogs with the help of comment kahuna software which is absolutely free and best alternate of scrapbox for those who can not afford scrapbox.
you can find some list of blogs that allow do follow at http://www.bloggingtipstoday.com/dofollow-blogs-list-587.html and at http://www.webcosmoforums.com/blogging/79030-best-blog-commenting-site-list-dofollow-links.html
Some blogs use the NoFollow Free Plugin and the name of this plugins folder is nofollow-free. Use it to find all blogs that have installed it by searching for "inurl:wp-content/plugins/nofollow-free" in Google. You can also look for similar plugins on http://wordpress.org/search/dofollow and do the search in the same way, ie.: - inurl:wp-content/plugins/no-nofollow - inurl:wp-content/plugins/dofollow - inurl:wp-content/plugins/ inurl:dofollow You can add some keyword before or after this command to look for the tematically related websites. But remember that such plugins usually remove the nofollow tag on some conditions, ie. after you post a few comments or if your comments are quite long so you will probably need to be an active used before you get dofollow links.
