How do you put an ad on Craigslist and what does it cost?

To post an ad on Craigslist, go to the Craigslist website, select your city, and click on "Create a posting." Choose the type of ad you want to post, fill in the required details, and add images if necessary. Most personal ads in most categories are free, but certain categories, like job postings in select areas, may incur fees typically ranging from $10 to $75. After submitting, you'll need to verify your email to activate the ad.
