Troubleshooting steps/questions:
Has this toilet always had this problem, or was there ever anything installed in this location that didn't clog like this? If the toilet has always had this problem then it's likely some issue with the initial installation; the drain pipe diameter may be too small, or there may be insufficient venting which is causing slow drainage in the wall because there's no "air behind water".
If it didn't always have this problem, then something has changed. Would that be anything obvious like a remodel, or something more gradual like build-up accumulation? If the toilet was replaced at some point, either as its own job or as part of a larger remodel, then most likely something was done during construction/installation that is causing an obstruction. If not, then mineral or organic build-up is the most likely culprit.
From the comments, what DID the plumber do, if he didn't scope the drain, lift the throne, and/or inspect the vent stack from the roof? Anything he did do, besides flush a toilet with nothing but clean water in it, may help to eliminate or diagnose potential problems.
Does the toilet always seem to drain slowly, even if it doesn't clog outright? Slow drainage of the bowl in all circumstances would point to an obstruction of the pipe diameter itself, such as an improper flange installation, a defect in the toilet, or blockage in the piping. Fast flow in a "normal" flush, but easy clogging, generally points to a foreign object blocking the pipe in such a way as to trap solids as they go down the drain, but allowing water without any solids to pass by normally.
Are there small children in the house? A child could have flushed a pencil, pen or other long, stiff object which is now caught in a turn in the plumbing and is trapping solid matter to form clogs. Scoping the drain will identify this blockage, and a professional snake will clear it (the homeowners'-variety snake with a coiled end won't do anything; you'll need a snake with bladed ends designed to chew into or through solid blockages, which require some knowhow to use without further damaging your drains).
I have a ground floor toilet that clogs every few days. Snaking with a 6 ft snake and/or plunging temporarily fixes the issue.
Wife is convinced that it's always tied to someone immediately pooping beforehand.
I am not so sure b/c there are a lot of times that it seems to clog and no one has pooped recently / immediately before the clog. Even under these circumstances, snaking and/or plunging seems to temporarily fix the issue.
None of the sinks, bathtubs, etc. have clogging issues. Just this one toilet.
Is it possible that the snake isn't really reaching the main clog / constriction? If so, how do I fix this? Longer snake?
Thank you.
Sorry. No photos, but I don't think it would be helpful here.
plumbing - Why does this toilet clog so often? - Home Improvement Stack Exchange
All the toilets in the house clog easily, but plunging clears them quickly. Pipes issue or just bad toilets?
Trying to figure out why toilet keeps "clogging" but often there's no obvious cause.

The first thing I would recommend is to use one of the other 2 toilets that don't clog. For the troublesome toilet, these are some clogging factors:
- Too much waste. Try multiple flushes or cut down on the amount of paper. Switch to a different brand of paper.
- A foreign object is in the toilet. Maybe a toothbrush or something that cannot be flushed is clogging the toilet line.
- Clog in the vent pipe, the plumber should had checked for this but a vent pipe that is clogged will effect plumbing and flush capability.
- Insufficient flush for the toilet design. Not all toilets flush equally, try replacing the toilet with one with a good flush. Toilets are pretty easy to replace. This may reveal other things as well like maybe the toilet is not seated properly (wax ring issue).
If there are no other clogging issues, then the problem is most likely localized to that one plumbing fixture, but if thre are other issues, then the problem may be further down the line which a plumber should be able to diagnose and fix.
