If you are looking for an old deleted post on Craigslist, here are a few ways to try to find the ad.
Craigslist posts usually expire after 7-45 days (depending type of post). So it can be tricky to find a specific post if it’s been awhile since you last saw it. Also know that if the post was deleted or flagged for removal before it was cached or archived by Google, then it is probably impossible to see the post again.

With that said, I will try to help you find that old Craigslist post with these tips.
Are You Trying To Find Your Own Expired Posts?
How to find old Craigslist listings:
This is the easiest way to find old deleted posts on Craigslist. If you’re looking for a post that you created but has expired, you can find it in your Craigslist account.
Go to https://accounts.craigslist.org/login
Log in to your account.
Then click the “All postings” link to see all of your previously posted ads.
Use The Wayback Machine To See Old Craigslist Posts
This tip only works if you have the exact URL/link where the ad was originally posted. Check your browser history on or around the date you saw the ad before it was removed from Craigslist. If you don’t know the exact URL where the ad was, then this will not work.
Go to the Wayback Machine: https://archive.org/web/
Copy & paste the ads’ URL into the search bar.

Then click the blue circles to find dates & archived versions (if they exist) for the Craigslist ad.
