Stop talking about job titles. Stop talking about the things that you do.
Instead talk about increased ROI, more conversions, decreased support costs, better PR, etc. Talk to potential customers about their problems first. Then give them solutions to their problems.
Ideally have stories from previous customers about those areas. Stories sell much better than skill lists.
For example a while back I sent this letter (lightly edited to removed some identifying material).
Hi $joe,
Thanks for talking to me last week about $company. From our chat it looks like your biggest problem was transitioning from startup geeks to long term customers. I think we can help.
We worked with $similar-company who had the same sort of issue reaching their long-term market. After helping them re-build their on- and off-line marketing materials their sales team saw a big increase in qualified leads, which helped them save money and focus their sales folk on some new markets. Conversions also increased significantly.
If you like I can put you in contact with their CTO and head of sales who can talk about their experiences with us.
If you'd like to talk about this further we should meet up. I could come and meet you next Friday afternoon in your offices. Drop me a line if this sounds interesting or if you have any further questions.
Cheers,
Adrian
Note how I'm not talking about user interviews, analysing their search engine results, a new visual design, user testing, new CMS, web design, HTML5, jQuery, agile development, etc. Despite the fact that we did it all for $similar-company.
Instead I'm saying "You told me this was you're biggest problem. Look we solved it for $other-company. Here are some people you can talk to for verification. Here is what you should do next".
Find out their biggest business problems. Show them you can help them solve it. Leave out the details of how until the last possible moment.
