A marketing audit is a comprehensive, systematic, independent and periodic review of everything that affects your firm’s marketing: the environment it operates in, its objectives and strategy, the activity itself and the results it produces. It tells you what is working, what is not and what to do next. In 2026 it also has to cover things like your data, your use of AI, and how your firm shows up when a client asks ChatGPT or Google for a recommendation.
What is a marketing audit?
The marketing audit has long been a recognised part of effective marketing management. It involves a comprehensive, systematic, independent and periodic review of a company’s marketing environment, objectives, strategies and activities. The aim is to identify areas for improvement and opportunities for growth, then recommend practical actions to strengthen marketing performance. Those four adjectives are still the test of a good audit, and the reason most firms do not have one is in the third: it is hard to be independent about your own work. The cost of skipping it is set out in our article on busy vs effective marketing.
The four principles of a good marketing audit
If you’re carrying out a marketing audit, keep the following points in mind:
Comprehensive
The audit needs to be holistic and look at the whole marketing function, not just analyse where a problem exists. An audit looks as much at where elements are performing well as where there is room for improvement. For a law firm that means every practice area and every channel, including the ones that “just happen”, such as referrals from intermediaries and repeat business, which are often the most valuable and the least examined.
Systematic
You will need to look at everything that influences marketing performance, whether it does so directly or indirectly. A systematic approach will allow you to analyse the micro and macro environment (using SWOT analysis), as well as your marketing principles, objectives, and strategies. Use the same structure every time, so that this year’s audit can be compared with last year’s.
Independent
We all have biases (whether they’re conscious or not!), and to avoid them clouding the results of the audit, you might want to consider employing a third party to undertake the marketing audit. They’ll also be free of any workplace politics that might currently be preventing the problem from being solved. If you go that route, our guide to what to look for in a professional services marketing agency covers the questions to ask.
When selecting someone to carry out the audit, you will need to allow them to completely submerge themselves in your activity to get a full picture of the business. While you are asking a third party to actually put together the findings of the audit you will still need to invest some of your own management time in the process if you want to get the best results.
Periodic
The marketing audit should not be a standalone event. A full audit as part of your strategic marketing plan need only be carried out once a year, or even every other year if your processes are really solid. However, it’s a good idea to audit your marketing activities more regularly to make sure you are still on track to meet your objectives. We always audit marketing activity quarterly so we can keep track of how different campaigns or tactics are performing. If you are not sure whether you are due one, our 7 signs your law firm needs to review its marketing strategy is a quick way to find out.
What are the components of a marketing audit?
The first thing to do is to check the feasibility of that which directly impacts the performance of your marketing. These are the firm’s mission, marketing objectives, goals and marketing strategies. It doesn’t matter how efficient your marketing activity is in achieving the objectives if those objectives are out-of-date or not helping you build towards the company’s future. This is where most audits find their biggest problem: objectives that were never written down, or that describe activity (“post three times a week”) rather than outcomes (“twelve new commercial property instructions a quarter”). We explain why most law firm marketing strategies fail in a separate article; the short version is that they were never connected to what the partners actually wanted.
The next thing you’ll need to do is write a SWOT analysis. SWOT stands for ‘Strengths, Weaknesses, Opportunities, Threats’ and allows you to lay out the macro (external) and micro (internal) factors influencing your business.
Environmental factors
The Macro-Environment is all the factors outside your business that influence the performance of your marketing. In the SWOT table, this is ‘Opportunities’ and ‘Threats’. Consider Demographic, Economic, Environmental, Political and Cultural impacts on your business. You should also consider the wider competitor landscape your business is based in. If you’ve ever written out a PESTLE analysis before, you’ll recognise these factors. In the SWOT, they stand together with internal factors to give you a bigger picture. For a law firm in 2026 the list includes interest rates and the housing market, regulatory change from the SRA and the Legal Services Board, consolidation among competitors, and the shift in how clients find a solicitor: BrightLocal’s 2026 consumer survey found 45% of people have already used an AI tool such as ChatGPT or Gemini to find a local business recommendation, up from 6% the year before.
Micro-Environmental factors are internal to your business. In the SWOT table, they’re the ‘Strengths’ and ‘Weaknesses’. There are a number of different types of micro-factor that you should consider:
The task environment
While these factors could be considered external, they are intrinsic to the marketing function. They are specific to the firm and therefore considered close enough to be in the micro-environmental audit. The task environment includes factors closely associated with the firm such as markets, sectors, distributors, suppliers, customers and competitors. For professional services, add referrers and intermediaries, the legal directories and review platforms that shape how you are ranked and recommended, and the handful of competitors clients actually compare you with.
Staff
Evaluate the performance of staff at different levels of the business and their influence on the marketing function. This can be difficult to do without bias, which is why we recommend an independent auditor! Look at engagement as well as performance: whether fee earners contribute content, share the firm’s posts and follow up leads, and whether anyone owns business development at all. Our 5 ways to increase staff engagement with your marketing is usually the first recommendation to come out of this section.
Marketing systems and data
Here you’ll need to measure several marketing systems. For example, marketing reports such as Google Analytics or social media reports. Your CRM and practice management systems, AI, client onboarding and offboarding technology need auditing too. Make sure to consider whether they’re up-to-date, need maintenance or further development. In 2026 this is the section that has grown the most. Check that Google Analytics 4 and Search Console are set up and that someone reads them; that enquiries are tracked from source to instruction, including phone calls; that the CRM holds clean, consented data; and that your reporting is consolidated in one place rather than scattered across platforms. Our legal digital marketing fundamentals guide sets out the minimum.
AI use and AI visibility
Two new questions belong in every audit. First, how is the firm using AI? Clio’s UK & Ireland Legal Insights Report 2026 found nearly nine in ten legal professionals now use AI in some capacity, and an audit should establish whether that use is governed by a policy, which tools are approved, and whether AI-drafted marketing content is being checked by a person before it is published. Our AI or Human? article sets out where the line sits. Second, how does the firm show up in AI search? Ask ChatGPT, Gemini and Google’s AI Overviews the questions your clients ask (“best conveyancing solicitor in Worthing”, “do I need a solicitor to contest a will”) and record whether you appear, what is said about you, and which sources the answers cite. That is your new competitor landscape, and client reviews are usually the biggest lever in it.
Marketing productivity
Evaluating the performance of the marketing activities in terms of profitability and cost-effectiveness. There are many marketing activities for which it can be hard to measure the ROI – mention this in your report. Where you can, work out a cost per enquiry and cost per instruction for each channel and compare them. The point is not precision; it is to find the activity that costs a great deal and produces nothing traceable, because there is almost always one.
Marketing function
Check on the firm’s core competencies such as the services offered, pricing, how and where services are delivered, marketing communications and the sales or business development function. Include the channels themselves: the website, social media, email marketing, events, PR and directories, and whether the brand is consistent across all of them.

A marketing audit checklist for professional services firms
Use this as the spine of the audit and add anything specific to your firm:
- Objectives – written down, outcome-based, tied to the business plan, and still current
- External environment – PESTLE factors, the housing and business cycle, regulation, competitors and how clients now search
- Clients and referrers – where instructions actually come from, by practice area, and which sources are growing or shrinking
- Brand and messaging – consistent across website, directories, social media, proposals and email signatures
- Website and search – technical health, rankings for the queries that matter, conversion from visit to enquiry, and visibility in AI answers
- Reputation – Google, ReviewSolicitors and directory reviews: volume, recency, rating, and whether anyone responds
- Channels – social media, email, events, PR, sponsorship and advertising, each with cost and results side by side
- Systems and data – analytics, call tracking, CRM, consent, reporting, and who looks at it
- People – who owns marketing and business development, fee earner engagement, skills and capacity
- AI – policy, approved tools, human sign-off on published content
- Budget – total spend, split by channel, compared with results and with what similar firms spend
What happens after the audit?
An audit that ends in a report has failed. The findings should become a short, prioritised list of changes, each with an owner and a date, and then a marketing plan that fixes the objectives first and the activity second. Our guide to building a law firm marketing plan takes it from there. Then diarise the next audit: a light quarterly review of activity against objectives, and the full exercise again in twelve months.
Why it matters
The marketing audit is a vital part of determining how successful a firm’s marketing is. It looks at how the business is performing marketing activities. It analyses how much they are adding to the overall performance of the organisation. Done properly and repeated, it is the difference between a marketing function that is busy and one that is effective.
Frequently asked questions
What is the difference between a marketing audit and a marketing plan?
The audit is the diagnosis: an honest review of where the firm’s marketing is now and why. The plan is the treatment: what to do next, in what order, with what budget. A plan written without an audit is a guess.
How often should a law firm carry out a marketing audit?
A full audit once a year, or every other year if the strategy is stable, plus a lighter quarterly review of activity against objectives. Bring the full audit forward if partners change, a merger happens, or enquiries fall without an obvious cause.
How long does a marketing audit take?
For a medium-sized firm, typically four to six weeks from first meeting to findings, including time for data access, staff and client conversations and the write-up. Management time is the main cost; budget for a few hours from each of the partners and the person who runs marketing.
Can we do a marketing audit ourselves?
Yes, using the checklist above, and a self-audit is far better than none. The limits are independence, time and the tools available: it is hard to judge your own work fairly, and the audit tends to slip behind client work. An external auditor removes both problems.
What should a marketing audit include in 2026?
Everything we listed at the start listed, plus your data and reporting, your AI policy and use, your reviews and reputation, and how the firm appears in AI-generated answers. Those are the areas where most firms have gaps and where the audit finds the quickest wins.
