How to Choose a Digital Marketing Agency: Scorecard, Questions and Red Flags

Last updated: 22 October 2026

Here is how to choose a digital marketing agency: write down your goal and budget first, shortlist three agencies that work in your channels, and score each one on the same weighted scorecard. Then ask every agency the same sales-call questions, confirm in writing that you own every account, and walk away from anyone who guarantees rankings or hides costs.

This guide is vendor-neutral. It gives you the scorecard, the questions, an account ownership checklist, the contract terms to ask for and the red flags, with every rule linked to the source it comes from.

Quick Answer: how to choose a digital marketing agency

You choose a digital marketing agency in six steps: set the goal and budget, pick the type of agency, shortlist three, run the same sales-call questions with each, score them on a weighted scorecard, and sign only a contract that leaves you owning every account. The table shows what each step should produce.

What should you decide before you contact any agency?

Before you contact any digital marketing agency, decide three things: the business result you want, the total amount you can spend each month, and which channels you want help with. Agencies will happily fill those gaps for you, and each one will fill them with the service it sells.

Use this short brief. It takes under an hour and makes every proposal comparable.

1. The goal in one sentence. For example, more booked calls from Google, more online sales at a set cost per sale, or more calls from the map pack.
2. The number you will judge it on. Leads, sales, revenue or cost per lead, plus where that number lives (your CRM, GA4 or the ad platform).
3. The total budget. Split it into media spend (paid to Google, Meta or Microsoft) and the agency fee. Our Google Ads budget calculator helps you size the media side.
4. The channels. SEO, Google Ads, Meta Ads, Microsoft Ads, email, content or a mix.
5. What your team keeps. Who approves ads, who writes product or service details, and who answers the leads.
6. The accounts you already have. List every Google Ads, GA4, Search Console, Business Profile and Meta asset, and who holds admin access today.

Do you need a full-service agency, a specialist or more than one?

A full-service agency suits a business that wants one team across several channels. A specialist suits a business where one channel drives most revenue. Two specialists suit a business that needs depth in two channels and has someone in-house to coordinate them.

If you are still weighing an agency against a hire, our PPC agency vs in-house cost guide runs the numbers. If you only need SEO, what an SEO company does explains the work month by month, and online stores can use our ecommerce SEO agency buyer guide.

How do you score and compare digital marketing agencies?

Score digital marketing agencies on the same eight criteria, rate each from 1 to 5, and weight them so the things that predict results count most. Before scoring, apply three pass or fail gates. An agency that fails a gate is out, however good its pitch.

The three gates:

• Ownership: you own every ad, analytics and listing account, and the agency gets user access.
• Written agreement: scope, fees and exit terms are in writing before you pay.
• No guarantees of rankings or fixed results: honest agencies give targets and ranges, not promises.

This weighted scorecard is our own model for a multi-channel engagement. Change the weights if one channel matters more to you, but keep the total at 100.

How do you calculate the score?

For each criterion, divide the 1 to 5 score by 5 and multiply by the weight. Add the eight results for a total out of 100. The example below uses three made-up agencies to show the math; it is illustrative, not a ranking of real firms.

Score each agency straight after its call, while the notes are fresh, and write one line of evidence next to every score. If two agencies finish within five points of each other, the reference call usually decides it.

What questions should you ask a digital marketing agency on the sales call?

Ask every digital marketing agency the same questions in the same order, so the answers can be scored side by side. The best questions ask for evidence: who will do the work, how results are measured, what you own, and what happens if you leave. Google’s guide to hiring an SEO suggests similar checks, such as asking for examples of previous work and the expected timeframe.

Three questions buyers often forget:

1. What will you need from us each month? Approvals, product data and lead feedback all slow results when nobody owns them.
2. What would make you advise us not to hire you? A good agency can name the cases it is not built for.
3. Which of your current clients can we call? A reference call tells you more than a case study.

Who should own your Google Ads, GA4, Search Console and Business Profile?

You should own your Google Ads account, GA4 property, Search Console property and Google Business Profile, and give the agency user access. Ownership means you hold the top role on each one, so you can add or remove the agency at any time. Google’s guide for advertisers says an agency must set up a separate Ads account for you.

Use this checklist before the agency starts work.

For a free audit, give read access only. Google’s hiring guide suggests granting an SEO read access to Search Console at first, rather than write access.

What happens to your accounts if you leave the agency?

If you own the accounts, leaving an agency is a matter of removing its access and collecting your files. If the agency owns them, you may lose history and have to rebuild. Community threads from business owners describe both cases, including agencies that refused access and offered only an export of the campaigns.

1. Confirm in writing the date the agency’s work ends.
2. Download reports, campaign exports, creative files and keyword lists.
3. Remove the agency’s users from Google Ads, GA4, Business Profile and your Meta business portfolio.
4. In Search Console, remove the agency’s users and delete its unused verification tokens. Google notes that a removed owner’s verification tokens are not deleted or revoked automatically.
5. Check that billing for ad spend is on your own payment method.
6. Update passwords for any shared logins, such as the website or hosting.

What happens to your conversion tracking when you unlink an agency’s manager account?

When a Google Ads account is unlinked from an agency’s manager account, it keeps its own campaign history and features. However, cross-account conversion tracking stops recording conversions for new clicks, and shared remarketing lists stop filling. If your conversion actions were created in the agency’s manager account, your bidding stops getting conversion data on the day you unlink.

Ask in the first week whether your conversion actions live in your own Google Ads account or in the agency’s manager account. If they live with the agency, have them recreated in your account and confirmed as recording before you give notice. One more check: if ad spend is billed on monthly invoicing through the agency’s manager account, ads stop serving unless billing is moved before the unlink.

What Google Tag Manager access should an agency get?

In Google Tag Manager, keep the account Admin permission yourself and give the agency container permissions, not only account User access. Account User access lets someone view basic account information but not create containers or change permissions, so container rights decide what the agency can actually do.

• Read: the agency can view tags, triggers and variables but cannot change anything. Good for an audit.
• Edit: it can create workspaces and make edits, but cannot create versions or publish.
• Approve: it can create versions but cannot publish, so you or your developer push changes live.
• Publish: full rights, including publishing to your live site. Give this only to the person accountable for tracking.

What should a digital marketing agency contract include?

A digital marketing agency contract should state the scope, the fee and how it is billed, who owns every account and asset, the notice period, and the handover steps if you part ways. Google also tells advertisers to get an official copy of the agreement in writing.

This is general information, not legal advice. Have a lawyer review any contract you are unsure about.

What are the red flags when hiring a digital marketing agency?

The biggest red flags when hiring a digital marketing agency are guaranteed rankings, agency-owned accounts, bundled fees that hide ad spend, refusal to share cost data, and secrecy about who does the work. Each one either breaks a platform rule or makes it impossible for you to check results.

Some signs are amber, not red. Ask about them before you decide:

• A setup fee. Fair when it covers real work such as a tracking rebuild. Ask what it buys.
• A minimum term. Fair when short and tied to a plan. A long lock-in with no exit is the problem.
• A percentage of ad spend fee. Common, but it rewards spending more. Ask how they decide when to cut spend.
• Proprietary scripts or tools. Fine to protect, as long as your account, data and campaigns stay yours.

How much does a digital marketing agency cost?

Digital marketing agency cost depends on the channels, the work and the pricing model, and ad spend is always on top of the fee. Google itself notes that partners often charge a fee in addition to the cost of your advertising. Compare quotes by model, not just by the monthly number.

For SEO, a survey of 260 agencies by SE Ranking and Duda found the most popular ranges were $500 to $1,000 per month, $50 to $100 per hour and $500 to $2,000 per project. Most agencies in that sample were small and served local businesses, so treat it as a market guide, not a fair price for your site.

For deeper pricing detail by channel, see our guides to SEO packages and real prices and PPC management pricing. To test whether a fee can pay back, try the SEO ROI calculator.

How do you check an agency’s reviews, case studies and partner badges?

Check an agency’s proof by asking for evidence you can verify yourself: dated results, a reference you can call, and partner status you can look up. A case study with no dates, no channel and no starting point tells you very little.

• Partner badges. Google’s advertiser guide explains how to check a Google Partner badge. A badge shows platform standing, not results in your industry.
• Reviews. Read reviews on several independent platforms and look for detail about the work. The FTC’s 2024 rule bans fake reviews and buying positive reviews.
• Case studies. Ask for the date range, the starting point, the budget and what the agency changed. Ask to see the numbers inside the ad platform on the call.
• References. Ask a current client what went wrong and how the agency handled it.
• Tracking. Ask how the agency checks that conversions are counted correctly. Our Google Ads conversion tracking page shows what a proper setup covers.

Does your industry change how you choose an agency?

Your industry changes how you choose an agency when it has ad policies, regulations or buying cycles that general agencies may not know. Regulated sectors such as financial services need an agency that can work inside approval and record-keeping rules. Ecommerce and local businesses need specific skills too.

How to choose a digital marketing agency for financial services

To choose a digital marketing agency for financial services, add one gate to the scorecard: can the agency work inside your compliance process? Ask who reviews copy, how approvals are logged, and how ads, landing pages and social posts are archived before anything goes live.

• Broker-dealers. FINRA Rule 2210 says a registered principal must approve each retail communication before use or filing, and communications must be fair and balanced with no promissory claims.
• SEC-registered investment advisers. The SEC Marketing Rule sets conditions on testimonials, endorsements and performance advertising, and advisers must keep copies of their ads.
• Google Ads. Financial ads fall under Google’s Financial products and services policy. Google’s June 2026 verification update applies to 24 European Economic Area markets, and it says agencies managing affected accounts also need verification, so ask about this if you advertise abroad.

Ask for examples of compliant ads the agency has written, with the client’s permission. This is general information, not legal or compliance advice.

Ecommerce and local businesses

Online stores should ask about product feeds, Shopping campaigns and margin-based targets, which our ecommerce SEO agency guide covers in depth. Local businesses should ask how the agency handles Google Business Profile, reviews and calls, and check its local SEO process.

What should the first 90 days with a new agency look like?

The first 90 days with a new digital marketing agency should move from access and tracking, to fixes and launches, to a first review against the goal you set in your brief. If month one is all new campaigns and no tracking check, the results you see later may not be real.

At day 90, re-score the agency on the same scorecard you used to hire it. A drop in the communication or reporting scores is often the first sign of trouble.

How long should you give a digital marketing agency before judging results?

For Google Ads, judge a new agency on at least two full conversion cycles after its last major bidding change, and longer if you get few conversions. A conversion cycle is the usual time between an ad click and a sale or lead. For SEO, Google publishes no fixed timeframe, so get the agency’s expected timeframe in writing.

The table sets out what Google itself says about timing, so you can tell normal settling-in from real underperformance.

Choosing a digital marketing agency: FAQs

How many agencies should I talk to before choosing one?

Talk to three agencies. Fewer gives you nothing to compare, and more than four usually turns into a pile of proposals nobody reads closely. Send all three the same brief and ask the same questions.

Are digital marketing agencies worth it?

A digital marketing agency is worth it when its work earns more than its fee plus the ad spend, and when it gives you skills your team lacks. It is rarely worth it before your conversion tracking works, because nobody can prove what is working.

Should I choose a local or a remote digital marketing agency?

Choose on skill, proof and fit, not distance. Remote agencies can serve local businesses well if they know your market and give you a set meeting time. Ask how they learn about your area and customers.

How do I know if my current agency is underperforming?

Re-score your current agency on the scorecard above. Warning signs include reports that show traffic but not leads or sales, no clear plan for next month, slow answers, and resistance when you ask for admin access to your own accounts.

Can a digital marketing agency guarantee results?

No honest agency can guarantee rankings or a fixed return, because platforms and competitors change. Google says no one can guarantee a #1 ranking. Expect targets, ranges and a plan instead.

What contract length is normal for a marketing agency?

Terms vary from month to month to a year or more. Whatever the length, check the notice period, any exit fee, and the handover steps. A short term with a clear exit is safer while you test a new agency.

Should I pay ad spend through the agency?

It is safer to have Google, Meta and Microsoft bill your own payment method, with the agency fee invoiced separately. You then see the true media cost, and the account stays tied to your business.

Should conversion tracking sit in my Google Ads account or the agency’s?

Conversion tracking should sit in your own Google Ads account. If conversion actions are created in an agency’s manager account, cross-account conversion tracking stops recording conversions for new clicks once that manager account is unlinked, so your bidding loses its data when you change agencies.

Do I lose my Google Ads history if I change agencies?

No, as long as the campaigns run in your own Google Ads account. Unlinking an account from an agency’s manager account keeps the account’s own campaign history and features. You lose history only when the agency ran your ads in an account it owns, which is why the ownership table above matters.

What should you do next?

Write your one-page brief, shortlist three agencies, and score them with the table above. If you want a second opinion on your current accounts or a proposal you have received, ask us for an audit; we look for wasted spend, tracking gaps and ownership risks.
