1. Conversion rates. Some would suggest that a copywriter should be measured by the conversion rate of the sales letters he or she writes. The only problem here is that I've seen some high conversion rates achieved by sloppy sales letters all because of the market these letters targeted.

2. Writing for famous clients. Many copywriters present as proof for their superior skills the fact that they have written for famous gurus. While I cannot blame them for flying these flags, many times these letters are used as a first draft and even chosen because of the low fees. That's right. Top gurus often go the low fee route and then adjust the copy themselves. So copywriting clientele is no proof either.

3. Top Trainer or Coach. If a copywriter was taught by a famous coach then it could be assumed that this would recommend them to be gifted by association. Who wouldn't want to be taught golf by Tiger Woods? But again having an excellent teacher doesn't make you an excellent student.

4. Length of time STUDYING copywriting. In this business of writing if you simply study about writing without actually practicing, then you'll remain a novice. You have to be in the trenches fighting the battle with many scars to prove your involvement and results to show for it. I'll prefer a gauge of the number of pages of copy written than the total length of time studying copywriting.

5. Amount of money earned. "Million dollar Producer", "My Copy Sold Billions"-these are the usual advertising blurbs we see advertising copywriting services. Now I don't personally have anything against making a lot of money, but this is often a gauge of one's business skills and the market you write for rather than your raw abilities. In other words, if you are 'lucky' enough to write for a big company with huge mailings, then it's highly probable the profit will reflect the company rather than the writer.
