10k vs 100k Facebook Page

Hello, I am planning to grow one of my 2 facebook pages, and I am looking for some advice on which one to choose.

One is about 100k likes and the second around 10k likes. I want to add for one of them another 100k likes, so:

10k -> 110k vs. 100k -> 200k

Some key points that I want to take in consideration are:

• Time
• Cost to grow
• ROI

Other Details:

• Growing Method: fb ads
• Website: is something similar to boredpanda
• Monetization: adsense

Both pages are linked to the same website (on the 100k I post all the stuff and the 10k is category based (but something broad).

In your opinion which one will be more effective to grow? (Taking in consideration: time, cost to grow, ROI)

Thank you if you are taking from your time to answer this.

10k to 100k
both faster and cheaper

Reason ?
besides fb ads you can share content of your 10k to 100k so u get fans faster and for free

but this is to save you time in the growing process

if you want to save time for future too then the 100 to 200k seems a better option because you will have to manage only 1 page instead of 2
so pick yourself

if i was you i would aim for more pages
but with what you have it's better to grow 1 page for it to be big enough and in the future you grow other pages by sharing them in your big page
