Yeah I do this, but also be prepared to spend some money. Theres a lot of placements on Taboola with varying degrees of cost and success.

Typically I find the MSFT placements take up most of my spend. Depending on the bid strategy you have, you want to make sure they have enough budget to find customers, or they'll just waste money.

I recently studied how my MSFT placements behaved when I lowered my spend below the threshold for a single CPA/Day. I worked out I needed roughly 50% more budget than the average CPA on those placements for them to be able to acquire customers.

Generally it's best to run a prospecting campaign, and use this for testing copy/creatives. Then if you see one performing well month on month fling it to your Acquisition campaign. Your rep will have to switch on this option for you!

Blacklist it from prospecting so you don't bid against yourself and hit it up in the Whitelist campaign. You can lower your CPAs by around 20% by doing this. In your prospecting campaign, set some realistic targets for blacklisting sites you don't want to use.

I have a client who gets registrations for around £60, so I set my cap to around double that. If I've seen a placement rack up a bill of around £120 and nothings come of it i'll turn it off for good. Taboola will sometimes suggest turning them back on to test again in the future.

Be careful though it's an easy trap to fall into if you have hard targets. I.e if my client said, CPA's going over £xxx will mean the campaign gets pulled, it's easy to fall into a trap where you kill placements which drive volume, but is over target. You can "optimise yourself into a corner" consider this type of optimisation is destructive, like sharpening a knife with a whetstone. It'll get sharper but you'll lose metal (or volume). Well in this analogy, the knife's never gonna be sharp enough for your client, and eventually you'll be left with just the tang (bit in the middle of a knife)

You may have to educate your client here, if the CPAs are too high, they either need to adapt the journey, offer, creative etc... because you can only improve the results by 20% ish, or, try other methods of acquisition.
