Are you running pop traffic?
Are you frustrated by the amount of time you're having to spend on ripping and fixing-up landers?
If you answer YES to both questions, here's an approach that can help to drastically cut down on the time you spend tinkering with landers - by using the same set of landers for multiple geos.
I'll keep this short and sweet:
Step 1: Identify the most widely-spoken languages in the world
Here's a nice chart with the info we want:

Chinese is #1 - not surprising. But most of them will be from China so if you're not planning on targeting China, then maybe it won't be worth your time to prepare Chinese landers. (Although: There are other geos that speak Chinese - SG, MY, TW.)
Spanish would be a GREAT choice! In addition to most geos in LATAM, there are also MX and ES.
English is of course another great choice - it's a language we're all familiar with, and many of us already have a set of English landers. Other than the competitive tier 1 geos - AU/NZ/CA/UK/US - tons of other geos also speak English as a major language. Some examples are: IN, PK, KE, GH, CM, NG, PH, SG, ZA, and UG. For a full list see:

Arabic is another good one. Many arabic geos can convert very well with good offers, and competition is not high. Some great geos are DK, EG, IQ, MA, SA, and AE. For a full list see:

I'll leave the rest of the languages for you to explore. 
Step 2: Identify the countries that speak those languages
I've kinda covered that above - here's where I went to get a list of geos that speak each language:

Step 3: Prepare one set of landers per language
This is self-explanatory - go to adplexity, select all the geos that speak that language, and rip all the different landers you see that are relevant to your offer type.
When fixing up these landers, you'll want to delete anything country-specific so you could use them across different geos - e.g. country flags.
