Running a social media audit: the step-by-step guide for agencies

Why an audit is the first step

Before an agency builds a social media strategy for a new client – or optimizes an existing strategy – you need to know where you stand. An audit gives you a baseline measurement: the baseline against which you will later measure your results.

An audit is also an excellent sales tool. By offering a free or low-cost audit as an entry point, you demonstrate expertise and expose the problems you can solve.

What you audit: the five components

1. Profile completeness

Check per platform: is the bio complete and up-to-date? Are there consistent profile and banner photos? Is the link in the bio correct? Are all contact details filled in? Is the category correct? These are quick wins that have an immediate effect.

2. Content analysis

Analyze the content of the past three months:

• Posting frequency: how many posts per week?
• Content mix: which formats are used? Which are missing?
• Best-performing content: what were the top five posts by reach, engagement, and saves?
• Consistency: is there a recognizable visual style?

3. Metrics benchmarking

Compare the metrics with industry averages:

• Engagement rate (average for Instagram: 1-3%)
• Reach per post as a percentage of followers
• Follower growth rate (month-over-month)
• Response speed to comments and DMs

4. Competitor analysis

Identify three to five direct competitors and analyze their presence on relevant platforms. What are they doing well? Where are the gaps? What themes do they claim? This provides strategic direction.

5. Technical setup

Are pixel tracking and conversion goals set up? Is the client account correctly linked (Business Manager, Creator Studio)? Are there security issues (unrecognized access)?

The audit report

A good audit report for a client has three parts:

1. Summary: the three most important findings and their impact
2. Findings per component: structured, with screenshots and data
3. Recommendations: ordered by priority (quick wins vs. long term)

Audit as a recurring service

Some agencies offer quarterly audits as part of their retainer. This keeps the strategy sharp and creates a moment for strategic discussion with the client. It is also an upsell opportunity: if the audit reveals gaps that require extra attention, you have concrete justification for package expansion.
