The Agency Perspective: What We're Actually Seeing in Client Accounts

After managing Google Ads campaigns across industries from healthcare, telehealth, medical, auto dealerships, education, insurance and legal to e-commerce, SaaS, home services and B2B services, we've developed a clear picture of what's working, what's not, and what the hype around AI-driven PPC is actually delivering in practice. This post is the honest version: the insights you won't get from Google's own marketing materials.

Google Ads PPC Tips

The Honest Pros and Cons of Google's AI-Driven PPC Changes

THE PROS

Advantage	The Reality
Dramatically better keyword reach	AI Max and broad match with Smart Bidding now capture intent-based queries that no keyword list could anticipate. Conversational searches ('who can help me get my website to rank higher in Miami') can now trigger relevant ads previously not possible.
Lower management overhead for straightforward campaigns	For simple lead generation campaigns with clear conversion goals, AI-driven campaigns genuinely reduce the hours required for routine optimization allowing agencies to focus on strategy rather than bid adjustments.
Superior creative testing at scale	Responsive Search Ads and AI Max can test thousands of headline and description combinations simultaneously. No human could run A/B tests at this volume manually. Winners emerge faster.
Asset Studio for creative production	Google's Gemini-powered Asset Studio generates high-quality images and video assets for campaigns. For businesses without a creative team, this removes one of the biggest barriers to running effective Display and YouTube ads.
Better bidding for high-volume accounts	Gemini 3-powered Smart Bidding genuinely outperforms manual bidding at scale. For accounts with 500+ monthly conversions, tROAS and tCPA targets are being hit with greater consistency than any previous iteration.
Improved PMax transparency	Channel-level reporting, negative keyword controls, and brand exclusion capabilities have addressed the most legitimate complaints about Performance Max. It's still not perfect, but it's significantly more accountable than when it first launched.

THE CONS

Disadvantage	The Reality
Reduced advertiser control	The shift to AI-driven campaigns means manual levers such as exact match keywords, specific bid adjustments, granular ad scheduling have been progressively deprecated or de-emphasized. If you prefer precise control, the current direction of Google Ads is frustrating.
PMax still cannibalizes branded traffic	Despite brand exclusion controls, Performance Max campaigns continue to bid on branded search terms in many accounts unless exclusions are explicitly configured. This inflates ROAS metrics by taking credit for conversions that would have happened anyway potentially misleading advertisers into over-investing in PMax.
Black-box attribution remains an issue	Even with improved reporting, the fundamental tension remains: platform-side reporting tells you what Google's algorithm thinks happened. Independent attribution via GA4 or a third-party tool frequently tells a different story. Always reconcile both data sources before making major budget decisions.
AI Max quality is highly dependent on input quality	Businesses with thin, poorly structured websites will get poor AI Max results. The AI crawls your site to generate ad copy if your pages lack clear, detailed service descriptions, the creative output will be generic. Garbage in, garbage out.
Poor performance for low-volume B2B accounts	Smart Bidding and Performance Max require significant conversion data to function properly. The generally recommended minimum is 30-50 conversions per month per campaign. B2B companies generating 5-10 leads per month will not see the benefits of AI bidding and may see significant budget waste.
Increasing click costs in competitive verticals	Broad match with AI Max often triggers ads for more queries, increasing total impressions and clicks = wasteful spend. Without constant, vigilant query monitoring and negative keyword management, impression share increases but conversion efficiency can decline particularly in highly competitive B2B service verticals.
Budget pacing change risk	The June 2026 budget pacing update (pacing to full monthly cap regardless of ad schedule) has already caused unexpected overspend for advertisers using limited schedules. This is an operational risk that requires immediate attention for any campaign using day-parting.

10 Expert Tips to Get Maximum ROI From Google Ads in 2026

1. Make your conversion tracking bulletproof before touching anything else.

AI bidding is only as good as the conversion data it learns from. Audit your Google Ads conversion tracking and GA4 configuration first. Ensure you're tracking the actions that actually matter like phone calls, form submissions, booked appointments not just page views. If your conversion tracking is wrong, every AI-powered optimization will optimize toward the wrong outcome.

2. Always run brand campaigns separately from AI Max and PMax.

Brand search campaigns (where someone types your company name) should be isolated in their own dedicated campaign with exact or phrase match keywords, not absorbed into an AI Max or PMax campaign. This protects your cost-per-branded-click from inflating and prevents AI campaigns from taking credit for organic brand awareness you've already earned.

3. Build and maintain aggressive negative keyword lists.

With AI Max and broad match campaigns casting a wider net, negative keywords are now more important than ever. Review search term reports weekly in the early weeks of any new campaign. Build a shared negative keyword list that excludes clearly irrelevant queries, competitor names you don't want to appear for, and any terms that historically generate clicks but no conversions. Keep in mind that even "exact match" in Google Ads is really exact match AND close variations.

Important AI Overviews Note: In April 2026, Google announced that Dynamic Search Ads are being automatically upgraded to AI Max by September 2026. AI Max, unless specifically opted-out of can insert text and final URLs it deems "more relevant" for your ads. Importantly, exact match and phrase match keywords will no longer trigger ads inside AI Overviews. Only broad match, AI Max, Performance Max, Shopping, and DSA campaigns can reach those placements!

4. For PMax: always upload manually created video assets.

If you don't upload video assets to your Performance Max campaign, Google auto-generates videos from your other assets. Studies show manually produced videos outperform auto-generated content by 25-40% on click-through rate and conversion rate. A 30-second testimonial or service overview video is worth the production investment.

5. Give Smart Bidding time and don't interrupt the learning period.

Every time you make a significant change to a campaign (new bid strategy, major budget adjustment (increase or decrease), new asset group, additional keywords, audience targeting adjustments, pausing and restarting a campaign), Smart Bidding and Automated Bidding enter a re-learning period of approximately 1-2 weeks.

During this time, performance often dips due to inefficiencies and ad costs increase, particularly CPL (Cost per Click) and CPA (Cost per Acquisition). More importantly, you a paying Google to "retrain" its algorithm. In some cases such as with tROAS, tCPA or value-based bidding - changes can take longer - 6 weeks or more.

Resist the urge to make additional, successive or big changes because when you do you'll reset the learning period and never allow the algorithm to stabilize. Plan campaign structure changes during lower-priority periods. Reduce budgets rather then pause or restart campaigns.

6. Improve your landing pages - AI now reads them for ad matching.

In 2026, Google's AI increasingly uses landing page content as a signal for ad relevance and creative generation. Pages need clear, detailed service descriptions, explicit calls to action, and content that aligns with the search queries you're targeting. A weak landing page no longer just hurts Quality Score, it now directly affects AI Max's ability to generate relevant creative.

7. Use audience signals as teaching tools, not restrictions.

A common misconception with Performance Max: audience signals don't restrict who sees your ads, they teach the algorithm where to start looking. Provide rich audience signals (your customer email list via Customer Match, website remarketing lists, in-market segments) to give the AI a head start. Monitor as it expands into adjacent audiences and exclude any that consistently underperform. Remember that Targeting narrows your audience focus vs Observation which widens the prospective audience focus.

8. Reconcile Google Ads reporting with independent analytics.

Never rely solely on Google Ads' own attribution for budget decisions. Compare Google Ads conversion data against GA4 goals, your CRM lead volume, and actual revenue data monthly. Significant discrepancies especially on Performance Max often reveal that the platform is overcounting conversions or crediting itself for organic and direct traffic.

9. Set realistic budget thresholds for AI bidding to function.

Target CPA and Target ROAS bidding require sufficient conversion volume to work. As a general benchmark, aim for at least 30-50 conversions, and ideally 70 to 100, per campaign per month before switching from Maximize Conversions to a target-based strategy. Under that threshold, manual bidding or Maximize Conversions without a target will often outperform AI bidding. Keep in mind that a bidding strategy change can take from 2 to 6 weeks to complete the relearning cycle.

10. Use AI Brief intentionally as it's the single highest-leverage input you control.

The AI Brief feature in AI Max is your primary creative steering wheel. Write it with the same care you'd give to a creative brief for a human copywriter: define your unique value proposition, your target customer, your differentiators, your tone, and your prohibited language (no prices, no competitor mentions, specific compliance language for regulated industries).

The specificity of your AI Brief directly determines the quality of AI-generated ad copy. It should be used with guardrails to control budget spend. Initially, you may wish to opt-out of Automated Text and Final URL Expansion to reduce wasteful spend. Designating landing page URLs, negative keyword and exclusion lists are essential to guard against wasteful ad spend.

Who Should Be Cautious About Full AI Automation

AI-driven Google Ads campaigns deliver their best results for businesses with high conversion volume, clear conversion goals, and well-structured websites. However, certain situations call for more manual control or a hybrid approach:

• Regulated industries (healthcare, legal, financial services): Automated creative generation can inadvertently produce copy that violates compliance requirements. Human review of all AI-generated assets is non-negotiable. Regulated industries such as Medical or Pharmaceutical, FINRA-related (Financial Services), some local services requiring licensing, and others have strict targeting, keyword, demographic and audience restrictions.

• Low-volume B2B lead generation: If your campaign generates fewer than 30 conversions per month, AI bidding lacks sufficient data and will underperform manual or Maximize Conversions bidding. While many ad managers will attempt implementation after 50 or 70 conversions, our experience has been that 100 conversions is a much better minimal target.

• Highly brand-sensitive businesses: If brand voice and specific messaging are critical, automated creative requires intensive oversight and detailed AI Brief configuration.

The Expert Verdict: Embrace AI, But Stay in the Driver's Seat

The transformation of Google Ads is not reversible. The platform is moving toward greater automation with each passing quarter, and the manual controls of 2019-era Google Ads are not coming back. The right response is not to resist this shift, it's to become expert at the inputs and guardrails that AI campaigns need to succeed: clean conversion data, clear creative direction, rigorous negative keyword and exclusions management, independent performance measurement, and disciplined budget controls.
