The Unconventional Way to Grow a Facebook Group With Facebook Ads
Part 5 Part 5 of 5: Publishing Your Game
Roblox lets you upload image advertisements for experiences, catalog items, groups, etc. When the ad is clicked, it goes to the page of whatever you're advertising.
I've read somewhere that 1 Robux is about 2 clicks for an ad. If I was going to advertise, I would probably spend 70 Robux over the course of 2 days, spending 35 each day. that would be an estimated 140 clicks, and most of the people who clicked probably wouldn't even bother to join the group.
Advertising is a good way to bring attention to the awesome stuff that you have built or made. You may even be able to make Robux by bidding on ads for an item which other players may then purchase or visit. For more information on how the advertising works on Roblox, please read through our Developer Hub article here.
Group creation requires a one-time payment of 100 Robux, per group. If the requirements are met, creating a group is fairly simple. Once on this page, fill out the Name, Description and Emblem sections.
"Beat my high score" advertisements would usually show a button and a line of text such as "I bet you can't beat my high score of 9001 clicks!", encouraging the player to click on the button and try and beat that score. These types of ads are now prohibited on Roblox as of June 26, 2016.
It probably got rejected due to ROBLOX moderation attempting to remove advertisements that talk about “clicking” or encourage the players to click multiple times. Even though yours does not encourage that, because it mentions clicking, that is probably why it was moderated.

10-100k is a sensible amount, if you can't start up off that you most likely won't. I did a test a while back and I spent 30 Robux for a desktop advertisement, it came out with 3,500 views, and only 13 clicks.
Basically, it all depends. Oh great a ton of answers haha, thanks. I spend 10 robux to make advertissement and I got 750 imprssions, 14 clicks and 6 - 8 visits. If you spend 1000 roblux, you will get 600 - 800 visits.
$200.00 = 16,000 Robux*
It can be purchased for 17,000 Robux.
10 USD3000 Robux is 10 USD by the DevEx exchange rate.
Once you have created the experience, group or piece of clothing of your dreams, it's time to get the word out so that other players can start enjoying the fruit of your labors. While word of mouth is a powerful tool on its own, Roblox offers several tools to help get you started. One of these tools is the User Ads feature.
Ads are images that players upload that can be use to promote their places, clothing, models, decals, groups, etc. These will be displayed at the top and sides of Roblox.com. When the image is clicked, it will take you to the thing that is being advertised.
