What "best" actually means in a Google Ads consultant — and why most rankings are unreliable

Search "best Google Ads consultant" in 2026 and you'll get pages of lists, rankings and "Top 10" articles. Almost all of them are paid placement. The criteria are usually vague ("strong client portfolio", "innovative strategies", "data-driven approach") and the order rarely correlates with actual quality.

That doesn't mean there isn't a "best" — there is, for your specific situation. It just means it isn't on a Top 10 list and you need to evaluate it yourself. Here's what actually separates the best Google Ads consultants from the average, based on running audits across hundreds of accounts and seeing the operators behind them.

The unglamorous markers that actually matter

1. Their answers get more specific the deeper you go. The average consultant gets vaguer when pressed. The best ones get more specific. Ask "what would you change in our account first?" — average answer: "I'd need to look at the account first." Best answer: "Without seeing it, I can already say I'd start with the conversion-tracking schema, because in your category 80% of accounts under-count high-value events. Then search-terms cleanup. Then bid-strategy alignment with your actual conversion volume."

The willingness to make falsifiable predictions before the engagement starts is a strong quality signal.

2. They tell you when Google Ads isn't the right channel. Average consultants will sell you a Google Ads engagement regardless of whether it fits. Best consultants will sometimes say "your category doesn't have search intent at the volume you'd need — Google Ads will work but you'll get more from other channels first."

Anyone who pitches you Google Ads in the first call without learning what you sell, what your average deal is, and what your sales cycle looks like — they're optimising for closing the engagement, not your business.

3. They have an opinion about your offline conversion data. Best consultants ask about CRM/sales data within the first 30 minutes. Average consultants don't. The reason: optimising Google Ads to platform-level conversions (form submissions, ad clicks) without offline-data feedback is optimising toward a proxy metric. The best consultants want the real metric.

If they don't ask about your CRM, your closed-deal data, or your average deal value — they're going to optimise toward whatever Google Ads says is good, not whatever your business actually earns.

4. They have a defined "no" list. Average consultants do "everything" — Google Ads, Meta, LinkedIn, SEO, email, sometimes web design. The best ones are explicit about what they don't do. "I don't run social. I don't write email sequences. I don't do SEO. I run Google Ads and Microsoft Ads."

This isn't because the best consultants are limited; it's because depth in one channel is more valuable than breadth across five. The "everything" pitch is a sign of a consultant who'll be average at all of it.

5. They show the same account they manage for someone else. Best consultants will do a screen-share walkthrough of an active account they're running (sometimes anonymised, sometimes with permission). They'll show you the structure, the search-terms cleanup cadence, the conversion-tracking setup, the reporting they send. You see the real work.

Average consultants show case studies — written-up after the fact, with metrics chosen to flatter. Case studies aren't proof. Active-account screen-shares are.

Markers that DON'T actually matter

A few things consultants market as differentiators that mostly aren't:

Google certifications. The Google Partners certification programme is now diluted — thousands pass annually, and it certifies platform knowledge, not strategic judgment. A certified consultant who's only done it via online study isn't necessarily better than an uncertified one with 10 years of accounts under their belt.

Premier Partner status. This is real (it requires meaningful spend volume and growth), but it's an organisation-level metric, not an individual-skill one. A small Premier-Partner agency might have one excellent operator and ten average ones. You'll get one of the eleven.

Number of clients. "We manage 80 accounts" tells you nothing about what each account gets. It can equally mean 80 well-run accounts or 80 maintenance-mode accounts.

Years in business. A consultant who's been running Google Ads since 2014 might have updated their playbook continually, or might be running 2018 best practices on 2026 accounts. The years-in-business number doesn't distinguish those.

Industry awards. Most are pay-to-enter or industry-back-scratching. There are a few credible exceptions, but as a category, they don't reliably correlate with account performance.

Useful things to ask before you hire

Five questions that quickly separate the good from the average, beyond the 9 questions for hiring a UK Google Ads expert:

• "What's the worst account you've ever inherited, and what did you change first?" — tests whether they have a diagnostic framework or just react case-by-case
• "What's the most surprising thing you've learned about Google Ads in the last 12 months?" — tests whether they're still actively studying the platform
• "Show me a monthly report you'd send us." — tests whether reporting is narrative-driven or just data dumps
• "What's the sign that we should fire you in 6 months?" — tests whether they have honest metrics for their own performance, or just expect retention by default
• "Who's a competitor you'd recommend if you weren't a fit for us?" — tests confidence and category awareness

A consultant who answers all five well, in person, on a single call, is in the top 10% of the market. They're the "best" — for you, in your situation.

Why "best for you" matters more than "best overall"

The "best" Google Ads consultant for a £3k/month e-commerce account isn't the same as the "best" for a £40k/month enterprise B2B account. Different category, different conversion volume, different bid-strategy needs, different reporting expectations.

A consultant who's brilliant in one segment may be wrong for another. The best consultants know their wheelhouse and will route you elsewhere if you're not in it.

This is why the real way to find the best consultant is to interview 3–4 with the questions above, then pick the one whose worldview about your specific account fits yours — not the one with the best LinkedIn following or the highest position on a Top 10 list.

What we are and aren't

WMI is a Google Ads consultancy — small senior team, retainer model, £3–30k/month range of accounts. We work in B2B, considered-purchase B2C, and lead-gen-heavy SaaS. We're a strong fit for accounts where senior judgment matters more than scale of execution; we're not a fit for accounts that need a 10-person agency team or for paid-social-heavy strategies.

If you'd like to test us against the questions above, book a free audit — it doubles as a scoping call. By the end you'll have a clear view of whether we're the right fit, and either way you'll have a sharper brief for the next consultant you talk to.
