If you have to try and make sense, then the order goes:
A Pup Named
Scooby Doo
Scooby Doo, Where Are You?
The New Scooby Movies
The Scooby Doo Show
The Blue Falcon Show
Scooby Doo/Scrappy Doo (With Fred and Velma)
New Scooby and Scrappy (With Daphne)
DTV (Boo Brothers, Reluctant Werewolf)
DTVs (Zombie Island, Witch's Ghost)
Scooby Doo Mysteries
13 Ghosts
Scooby Doo/Scrappy Doo (W/O Fred, Velma and Daphne)
What's New Scooby Doo
A way to explain away 13 Ghosts is to say either
A) It was nothing more than a nightmare that Scooby had
B) After the 13 Ghosts were caught, Van Ghoul took Flim Flam in while Scooby and the others went back to their non real ghost hunting lives.
After the beginning of Zombie Island, where the gang breaks up, that's where New Scooby/Scrappy - 13 Ghosts (I'm going with the whole bad dream opinion) occurs. After that, Daphne goes off to become a journalist, which is where the Scooby Doo/Scrappy Doo show and the 80's DTV's happen without the rest of the gang happens. Scrappy can be assumed to go back to live with his mom (or if you go by the live action film, dropped in the middle of the desert), which is where Zombie Island picks up with Daphne on the reality show, hiring Fred after his book career goes down in flames and Velma is fired from NASA for "meddling too much" and opens her own book store.
Now, if you really want to get confusing, figure in "Laff-A-Lympics".
