You have to load at least one saved Hotlap onto LFSWorld to join the ranks.
Can be any car/track combo, including reverse config (but not X or Y configs).
The more combo hotlaps you load, the higher ranking you will get.
Ranking is achieved by both quantity and times compared to World Records. Lap times close to WR times will be shown with green background, and outwith a selected percentage (offhand, can't remember it) times will be shown with red background.
Click on 'S2 Hotlaps' app (then Ranks tab) on LFSWorld to see the full rankings.
Even if you only submit 1 combo within few seconds of WR, this will put you quite high up the rankings - just in the top 3000 out of (currently) 7795.
If you do one of 18 specific car/track combos, and load that hotlap, you also get on the Main Hotlap Rank (MHR) rankings. Click on one of the leaders in that section, and you will see what the combos are.
