From September 2019, budget optimization on Facebook will become the default setting.

It will not be possible to turn off budget optimization for new and already running campaigns.

What to expect

Optimizing a campaign’s budget will allow you to adjust the total budget for all ad groups in it, and then automatically reallocate it in real time to the most successful ad groups.

This will allow us to achieve better results with the available budget and thereby reduce the overall price for the result.

Optimizing campaign budgets can bring more results at a lower price.

When using campaign budget optimization and the lowest bidding strategy, you will be able to get a minimum price per result for the entire campaign, rather than individual ad groups.

And another moment for fans to delete information.

Now in the FB message can be deleted for all participants in the chat / conversation, the main rule is not more than 10 minutes after sending.
