Why Google's Recommendations Are Mostly Traps

Google's recommendations aren't there to help you. They're there to help Google.

Most paid media accounts I audit are a slow leak. Not catastrophic — just bleeding ten, twenty, thirty percent of spend on waste that nobody's looked at carefully in a year. Wrong match types. Unfiltered placements. Broad-targeting "recommendations" accepted because the rep said so. Performance Max campaigns optimizing for "anything that moves" because nobody set the signals correctly.

That's how you get to a point where the spend is up, the pipeline isn't, and nobody can tell you why.

That's the work I do — find what's leaking, fix it, and get the account competing again.

What I actually look at

Every paid media audit runs the same core checks, then goes deeper wherever the account needs it:

  • Search campaigns. Match type discipline, negative keyword hygiene, query reports, quality score drivers, ad group structure. The fundamentals that most accounts drift away from over time.
  • Performance Max. Audience signals, asset groups, brand exclusions, whether it's cannibalizing your other campaigns, whether you should be running it at all for your category.
  • Google recommendations. Which ones to implement, which ones to quietly ignore, and which ones will silently tank your account if you accept them.
  • Placement and location exclusions. Most accounts show ads on sites, apps, and geographies that cost money and convert nothing. Excluding them systematically is one of the highest-ROI moves in paid media — and most teams don't do it.
  • Creative and landing page match. If your ad promises one thing and the landing page delivers another, your quality score and your conversion rate both pay the price.
  • Tracking and attribution. If your conversion data is lying to you, every optimization decision afterward is wrong. I check this first, always.
  • Budget allocation. Most accounts overspend on branded search and underspend on the campaigns that actually acquire new customers.

Channels I cover

  • Google Ads — Search, Display, Shopping, YouTube, Performance Max
  • Meta Ads — Facebook and Instagram, including B2B retargeting and ecommerce catalogs
  • LinkedIn Ads — for B2B, where the targeting premium actually earns its keep
  • Microsoft Ads — the most underused channel in B2B paid media, usually 20–30% cheaper than Google for the same search intent
  • Amazon Ads — for D2C brands selling in both owned channels and marketplaces

Twenty years managing paid media across B2B and B2C, with over a million dollars a month of managed spend across my career. I know the difference between a campaign that looks healthy and a campaign that actually performs.

Who this is for

Companies spending real money on paid media who want to know where it's going:

  • B2B SaaS and fintech running Google + LinkedIn
  • D2C and ecommerce running Google Shopping + Meta
  • Lead gen businesses running high-volume search
  • Agencies that need a senior operator on the accounts they can't staff
  • Private equity portfolio companies where the paid media budget needs adult supervision

If you're spending under $5K a month, you probably don't need me yet — your time is better spent on SEO or content until your paid media is scaled enough to matter. If you're running an in-house team of ten with a full Google partner relationship, you've got what you need. Everywhere in between — $10K to $1M+ monthly spend — I can help.

Frequently asked questions

Which Google Ads recommendations should I actually implement?

Generally safe to implement: bid adjustments based on performance data, negative keyword suggestions from query reports, and ad extension additions that match your business. Approach with caution: match type broadening (especially to broad match), auto-applied recommendations, and budget increase suggestions. Almost always skip: "switch to Performance Max" recommendations for B2B accounts and "accept all recommendations" auto-apply settings.

Will declining Google Ads recommendations hurt my optimization score?

Yes, but optimization score doesn't correlate with account performance. It's a Google-constructed metric that rewards accepting recommendations, not account health. Most well-run accounts have optimization scores in the 50-70% range because the account managers selectively ignore recommendations that don't serve client goals.

How often should I audit my Google Ads account?

Full account audit at least quarterly. Ongoing maintenance reviews weekly for match types, search terms, and creative performance. Monthly reviews of budget allocation, PMax signals, and landing page performance. Accounts that get quarterly audits drift; accounts that get weekly maintenance stay competitive.

What does Performance Max actually do?

Performance Max is Google's automated campaign type that serves ads across Search, Display, Shopping, YouTube, and Discovery based on conversion signals. It's effective for ecommerce and high-volume transactional businesses. It's often counterproductive for B2B and considered-purchase businesses because it prioritizes volume over quality. Auditing whether PMax is driving incremental conversions or cannibalizing your search campaigns is essential.

Why does Google keep making recommendations I shouldn't follow?

Google's recommendation system is optimized to increase spend and automation adoption, not to maximize your ROI. Broader match types, higher bids, and Performance Max all tend to increase Google's revenue — whether or not they improve your account. Treating recommendations as starting points for analysis rather than instructions to execute is the right operating posture.

What does a paid media audit actually cost?

A full paid media audit at Corriston Consulting is a fixed-price three-week engagement covering all active channels — Google, Meta, LinkedIn, Microsoft — plus tracking and attribution review. Pricing scales slightly with account size but runs in the low five figures. The audit includes a written prioritized report and a 60-minute findings call.
