Skip the Ads That Don't List the Business Name or Has Typos

This is from Otesa Miles, a successful freelance writer on the subject of finding jobs through boards:

I've almost completely stopped replying to job-board posts.

I used to only reply to the ones that listed a name,
website or something tangible. I also ignored the ones with tons of errors.
After responding to probably 100+ ads, I received maybe 10 legitimate
replies and landed one job from a company working with a well-known
publisher.
If I'm bored, I'll respond to one or two ads to add spice to my day,
but I no longer consider it part of my regular marketing mix.
