Landing page guidelines
Your ad may not be approved if the landing page content isn't fully functional, doesn't match the product/service promoted in your ad, or doesn't fully comply with our Advertising Policies. To create a positive ad experience, please keep the following in mind:
Don't:
* Direct ads to landing pages with minimal original content, low-quality content, or content that is difficult to access.
* Distract from your landing page's original content with excessive embedded or pop up ads.
* Bait people into clicking on ads by using overly cropped ad images or shocking or sexual ad copy.
* Attempt to monetize Facebook ad views. For example, Facebook ads shouldn't link to a destination page that requires people to click through other ads to access the site's content.
* Use low-quality advertisements or shocking or sexualized ad imagery.
Do:
* Present the content up-front, clear, and easily navigable.
* Ensure the content on your landing page is relevant to your ad. Directing people to irrelevant content or an unexpected landing page can create a confusing and negative experience.
* Clearly connect the branding in your ad with that of your landing page.

Explanation
Every time you work with a new client, your best audiences will always be Custom Audiences and Lookalike Audiences.
For physical locations, you want to re-market to existing customer databases.You want to use a custom audience of people who have already bought at the store to promote re-purchases.
You then want to use this database and use a similar/lookalike audience so that you can bring new potential customers over. Because you are using Facebook offline events, you can even segment people based on long-term value of sales.
The last audience you should be using is a saved/core audience, but you should always start with the other two first.
