Sometimes in areas like Customer Service or Sales get most responses but I don't recommend putting any links on CList. Well if it is at least in the General Gigs or Computer Gigs section.
I would recommend you use your time more wisely with Facebook or on your blog for example rather then posting on classified ads in hopes to catch to catch someone.
I absolutely agree. Unfortunately Craigslist is full of people still trying to spam. Even if you follow every posting rule, your post may still be flagged and ghosted. There are better ways to promote like Social media as Peter mentioned.
Agreed. Instead of breaking their rules (since it is their service), just find other places to advertise. Think about it - what were the TRUE chances of someone reading your ad or clicking your link anyway? This is particularly true if it is in the wrong category or uses some sort of deceptive headline. Do you know how many "Writer needed" ads I flagged because it ended up being surveys?
