Same as say adroll etc. that includes GDN... I prefer just running on GDN in Google Ads, more options etc... I guess this is just for ppl that want it all in one platform vs. each individual one.

Now, you should know the difference between for example imported GA conversion in Google ads, or the G ads conversion pixel.
- GA:
Only last touch will count, so if last touch --> conversion then no conversion in G ads
- G Ads conversion pixel
Will still record a conversion

The question how do they guarantee results? I doubt they have some sophisticated algorithms and are not like Marin/Kenshoo etc..
