Social media advertising
Social media remarketing setup services
Remarketing services set up the audiences, exclusions and ads that reach people who have already visited your site, engaged with your content or bought from you. Because remarketing relies on tracking and personal data, the first thing a careful provider checks is compliance: whether the Pixel waits for cookie consent and whether you have a lawful basis to use customer lists. After that, the quality of the work shows in exclusions that stop ads to recent buyers, messages tailored to each audience, attention to how often people see ads and honest measurement of whether remarketing adds sales or simply takes credit for them.
This guide covers questions to ask, data handling, warning signs, deliverables and how to judge the work. LetGetGrow sets up and manages Facebook and Instagram advertising, with the scope, management fee and reporting set out in a custom quotation.

Questions to ask
| Question | Good answer shows |
|---|---|
| How will you check consent? | A test that the Pixel waits for consent |
| How will customer lists be handled? | Hashed upload, lawful basis confirmed with you |
| Which audiences will you build? | By action and time, with reasons |
| How will you avoid annoying people? | Exclusions and frequency checks |
| How will you show it adds sales? | Total sales comparisons, not just attributed sales |
Data handling
If customer lists are to be uploaded, ask who prepares the file, how it is transferred and deleted afterwards, and how the provider confirms the lawful basis with you. Meta's documentation says customer data must be hashed. You remain responsible for the data, so the decision to use it is yours.
For website audiences, ask the provider to show you that the Pixel does not load before consent. ICO guidance says non-essential tracking needs consent actively and clearly given.

Example: a compliance-first set-up
Illustrative example — not a client case study
Situation: An online bookshop asks for remarketing to past visitors.
- The provider finds the Pixel loads before the consent banner is answered and asks the bookshop's developer to fix it.
- Audiences are built for product viewers and basket abandoners, excluding recent buyers.
- After a month, the provider compares returning-visitor orders with the previous period alongside Meta's attributed figures.
What this shows: Remarketing ran lawfully and was judged on added orders. This example is illustrative.
What you should receive
Compliance
- Consent test result
- Privacy information notes
Set-up
- Audience and exclusion list
- Ads for each audience
Measurement
- Added sales comparison
- Frequency notes
Messages for each audience
Someone who viewed a product needs a different message from someone who left a full basket, and both differ from an existing customer. Ask the provider for a short message plan, rather than one ad shown to every remarketing audience.
Fees
Set-up is often a one-off fee, with running remarketing part of ongoing management. Consent fixes may need your developer. Ad spend is paid to Meta.
Audience windows
Ask which time windows the provider proposes, such as visitors in the last week versus the last few months, and why. The answer should reflect how long your customers usually take to decide, not a standard setting applied to every client. Different windows usually deserve different messages.
Frequency control
Remarketing audiences are small, so people can see the same ad many times. Ask how the provider will watch how often people are reached and what it will do when that rises: refresh creative, widen the audience window or reduce budget.
Access and ownership
Audiences, the Pixel and the ad account should belong to your business. Give the provider a role through Meta's business tools and remove it when the work ends. Audiences built in your account remain yours.
What to share
Share your consent tool details, privacy information, which actions matter on your site, product images and whether you want to use customer lists.
Testing whether it adds sales
Ask whether the provider will run a simple check, such as comparing returning-visitor sales during and before remarketing, or briefly pausing it, to see whether it adds orders. A provider confident in its work should welcome the check. Relying only on attributed figures tends to flatter remarketing, because its audiences are already likely to buy.
