Ad Reach Limited by Facebook

Hi, was running FB ad and got this message: This ad was marked as low quality, so it will be shown to fewer people than would typically see it for its current budget. Performance may improve by reducing low-quality characteristics such as language that entices people to inauthentically engage with the ad or landing page to complete an action (i.e. liking the post, commenting on it or sharing it with a friend) in the ad text.

I did not ask to like, share, or comment.

Simply written in ad copy if you want the giveaway, go to URL and submit entry.

What could be the reason for this?

Could be your lander, test the URL through Fb's debugger & see if any red flags come up https://developers.facebook.com/tools/debug/
