http://robcubbon.com/web-designers-wordpress-developers-get-clients-online/ This is from a talk I gave yesterday at the London WordPress Meetup. I talk about how you can work out keywords that describe you and what a potential client can type into a search engine to find you and then how you can target those keywords with "buying intent". I also talk about how you can improve your authority. Make sure you appear on local searches. Vary the types and platforms of the content you produce. Increase you authority. Help other web designers and developers. And change the calls to action on your website.
