A great addition to your PR armoury is a blog or two, optimized for the cuddliest keywords in your life. Once you’ve established the blog, all you need to invest is a couple of hours twice a week to keep the momentum going with the search engines and to maintain your blog’s ranking.
Even better, your blog can be cathartic: that is to say, you can get all those things off your chest that have been bugging you all week. Far better than having a rant at a supplier or employee, cheaper than getting pissed and much safer than plonking someone on the nose.
From a SEO point of view, it may be beneficial to set up a blog which is linked directly to your website so you get all the SEO spin-offs and the added bonus that traffic is coming direct to your main website and not to your standalone blog which is a few clicks away at best. http://wordpress.org is the place to go if you’re interested in integrating a pro blog into your website.
