Explanation
Bidding strategies help you control the overall spent with budget constraints.
There are basically two bidding options: Lowest Cost or Target Cost
1. Lowest Cost
The lowest cost bidding strategy tells Facebook to get the lowest possible cost per result, while also spending your entire budget.

2. Target Cost
The target cost bidding strategy tells Facebook to get as close as possible to your cost target. This option is only available for app installs, conversions, and catalog sales marketing objectives.

In this case you need to have a "Lowest Cost" strategy as you want to achieve the following:
- Limit the app install at $9.00
- You know you can't afford a higher cost of $9.00 as it won't be profitable for your client Keep in mind that lowest cost budget will achieve your costs results but might not get you results as you might be bidding lower than the auction requires for your ad to be competitive.
You should start with lowest costs and then could potentially move to target cost once you've achieved at least
50-75 app installs and you have a better understanding of real costs for your client.
You should also move to target costs if you are not getting enough app install results with your first campaign.

Explanation
Every time you work with a new client, you want to first analyze the behaviors, demographics, and segmentation from their current customer base.
The main objective is to use all of this information and build a new core/saved audience based on all of these insights. If you see specific Fan Pages that the customer base follows, you want to include all of those interests in the new audience.
So all of the information that comes out of Audience Insights is for you to use and build better audiences based on facts, and not assumptions of whom the potential target market is.
Use actual data from customers to reach out to new potential customers.

Explanation
Every time you use databases, you need to make sure you segment your database first, depending on the requirements. In this case, you need to find the customers with the best lifetime value.
You DON'T want to upload all of the databases, as you won't be able to segment on Facebook.
Once you've segmented the database, you should proceed to upload the database to build a custom audience.
This should allow you to use this audience as a seed audience. Because you've already segmented the database; you know that these are the users with the highest LTV.
You then use this to build a similar audience optimized for similarity, as you are trying to reach potential new customers that have the most similarity with your client's customer base.

Explanation
Since you are trying to increase sales on a short period of time, you want to reach out to users who've interacted recently with your client's content and initiated a checkout process.
In this case, you want to launch campaigns for two specific audiences:
1. People who've registered but have not finalized the checkout process. This audience is probably your
"low-hanging" fruit. Someone who has registered, but has not completed payment, probably just needs a small push to complete the purchase.
2. Users who have read specific content related to client's products, are probably the second best audiences you should reach. These are users who have shown interest in your client's products and might be interested in making a purchase.
You don't want to run the campaign on new audiences yet. So running a campaign to a saved or similar audience is not the right choice for your first campaign.

Explanation
There are four bidding options you can pay for the delivery of your ads:
1. Cost per Impressions (CPM)
2. Cost per click (CPC)
3. Cost per conversion
4. Cost per Action (CPA)
Depending on the type of bid that you set up initially, you are configuring several aspects of your campaign:

In this case, since you want to compare reach, your optimization should be for impressions (CPM) and also optimize for impressions.
