How to compare social media agencies by normalising quote scope

What to take away

Why are quotes not comparable yet?

Two agencies can quote the same monthly fee and mean different things. One includes community management on four channels. The other counts publishing only and bills replies separately.

Until scope is normalised, price tells you little about value. A structured social media agencies review methodology forces the same evidence from every supplier before scores are given, which is what makes a later comparison fair.

What should you fix before you score anyone?

Fix the scope, the reporting pack and the review dates first. Changing any of them mid-process invalidates the scores you have already given.

Set one reporting pack: platform metrics, spend, engagement rate and a short written commentary. Ask every agency to price that same pack.

Agree contract length and notice period in advance. Rolling monthlies and twelve-month terms change your risk, not just your cost.

Give each supplier the same brief and the same deadline. Differences in the response then reflect the agency rather than your process.

Put the agreed scope in writing and send it to everyone. Verbal changes during the process are the most common reason comparisons collapse.

Where does the data protection check fit?

It fits before commercial scoring, because a poor answer can remove a supplier entirely. Your agency processes personal data whenever it handles comments, messages or lead forms.

Under the Data Protection Act 2018, you remain responsible for lawful processing as controller. Ask for processing terms, retention periods and a sub-processor list.

If an agency cannot say where data is stored or how long it is kept, treat that as a failed answer. Do not average it into a score to keep the shortlist tidy.

How do you compare performance claims?

Ask for evidence, not adjectives. Request three months of platform screenshots or exported reports from a comparable account, redacted if needed.

Where paid social is part of the brief, ask how leads are captured and followed up. LinkedIn sets out its own lead generation ads formats, so you can test whether an agency's plan matches what the platform actually offers.

Score evidence quality separately from price. A cheaper quote with no evidence is usually the more expensive choice. Keep a note of who supplied each figure so you can trace it later.

Before and after: what changes when you normalise scope

The table shows the fields that change most often between suppliers.

For example, a team paying £3,000 a month may find that one quote covers publishing only while another includes moderation. The second is not necessarily dearer once the missing work is priced.

Common questions

When should we start comparing agencies rather than reviewing one?

Start when your brief is stable and you can name the channels, outputs and reporting you need. Comparing earlier produces scores you will have to throw away.

How many agencies should be in the comparison?

Three is usually enough to expose pricing patterns without overloading your team. Add a fourth only if the first three differ widely in model or specialism.

What should disqualify an agency immediately?

Missing processing terms, no performance evidence at all, or a contract that cannot be ended within a reasonable notice period. Each is a structural risk rather than a negotiating position.

How often should the comparison be repeated?

Repeat it at renewal, or sooner if your channel mix changes materially. The social media agencies reviews and comparison methods guide sets out how to keep rounds consistent.
