I received an email from WritingAssist.com that included a "Guide to Estimating Writing Projects". Please, note that I have no affiliation with WritingAssist.com.

Seeing that copywriting is vital to conversion, I figured I'd share the resource. The guide does a nice job of breaking down the required time and effort for various levels of copywriting projects. Additionally, WritingAssist.com has a nice resources page which includes some handy articles for technical writers and marketers alike.

If you have other copywriting resources that you use, please share them. Copywriting is one of the most overlooked aspects of conversion optimization, and clarity in your message can often provide huge boosts to conversion rates.
