Is this true?? If use china fb acc, more Efficient advertising is possible?

If run an facebook ad with an overseas advertising account, such as China or Taiwan, you would say that the cost-to-revenue ratio is effectively enforced. Is this true?

I don't think so.Why would Facebook give preference to advertisers in China?

First of all, Facebook has a 7 year ban from China, and to lift the ban they have to made some major chances on the platform so don't count on it anytime soon. On the other hand, Facebook is eager to get into the China Market, so it might be true that ads could cost less on that give country, i heard a rumout that if you change the LANGUAGE on the ads, they come cheaper, buy really haven't tried it.

Facebook only gives special treatment (low cpc or oCPM in this case) to ads that have high RS, meaning they want to deliver USEFUL service that resonates and responds well its respective target group.

It's quite a simple demand/supply concept, if a lot of people like your ads, they will engage it in large numbers, so Facebook has to lower your CPC so they don't break your budget, if your ads are irrelevant or straight up an eyesore, people will not engage and Facebook will charge bigger buck because the demand is low.

Plus, if it's that simple to save cost, people would just try to fake their identity EASILY to get cheap advertisement.

Like Roundrex said, Facebook is not allowed to visit in China, government BANNED it! And what Zuck has done these years are useless till now.

If what you heard is some truth, that maybe the Taiwan ads done the difference?!

Hello howdy.
Is true that if you use Fb Ads accounts of certain countries you can get cheaper cost of the ads.
But its not related at the country it self. Its related to the currency exchange price.
These "bug" happen when Facebook doesn´t upload the exchange rate of that country related to the US currency (main currency of fb ads).
These doesn´t happen generally on big countries or countries that have big influence on Facebook as Facebook is constant checking the rate. These bug generally happen with countries that in a way the exchange rate is not uploaded by Facebook so it benefit us (advertiser).
To check if the country it benefit or not you should check the thresholds. See when it hit the first threshold and compare it to the current price of it (25 U$S) to check if the benefit will help you or not.
