The product team reality

You know the product.
The ad copy doesn't.

Your team understands the technical capabilities, the integration depth, the actual problems users face. Translating that into ad copy that resonates with search intent is a different skill. And every minute spent on it is a minute stolen from shipping. Hand a generic tool your homepage URL and it writes from the words already on the page. The reasons people actually pick you over Datadog live in your team's heads, not in the hero section a scraper can read.

Generic AI copy

// no product context
  • "Transform your business with AI"
  • "Industry leading platform"
  • "Unlock new growth"
  • "Best in class solution"

Could be any SaaS. Google's algorithm picks what to show.

Hero Marketer

// product profile loaded
  • "Monitor API latency without writing alerting rules"
  • "Catch the 1% of slow requests your dashboards miss"
  • "Built by engineers who got tired of Datadog bills"
  • "Open source alternative to Datadog APM"

Sounds like the person who built the thing.

From the desk of a PLG operator

Three real questions, where
most tools default to ecommerce.

Three case files from product led B2B SaaS operators running paid alongside the product. The question on the tab, the answer in the file.

FILE 01 · Trial signup rate dropped

When you ask

"Why did our trial signup rate drop last week? Was it ad quality, landing page, or upstream?"

Needs PLG reasoning, not a 'high CPC, pause it' instinct.

Hero AI · Investigation (PLG track)

Click volume flat. Ad strength flat. The drop traces to landing page conversion: the new pricing experiment ships visitors to /start instead of /free, and /start requires a credit card upfront.

BOFU intent terms (Free, Pricing, Demo) are hit hardest, the cohort least likely to leave a card before activating.

Revert the BOFU clusters to /free. Keep the /start experiment on Comparison and Problem aware clusters, where intent is closer to evaluation. Want me to map the keyword level URL splits?

FILE 02 · High-CPC pricing campaign

When you ask

"Our BOFU 'pricing' campaign is showing high CPC. Is it still actually converting?"

The trap every generic AI tool falls into: pause the expensive term.

Hero AI · Keyword Research + Investigation

CPC is $11.40 (up 24% YoY). Conversion rate is 9.2%, and cost per conversion is $124, the lowest of any cluster in your account.

The keyword does exactly what BOFU keywords should: capture buyers who already decided. CPC is a vanity metric here. Cost per conversion is what matters, and it is strong.

Protect the cluster. Do not pause, trim, or lower the bid. The high CPC is the cost of reaching the right buyer. Want a short writeup defending this to your CEO?

FILE 03 · PMax leaking to Display

When you ask

"Audit our Performance Max. I think it's leaking budget to Display."

The exact failure mode PMax falls into for B2B SaaS.

Hero AI · Investigation → Recommendation

PMax network breakdown, last 30 days: Display 71% of spend, 14% of conversions. Search 19% of spend, 68% of conversions. YouTube 10% of spend, 18% of conversions.

The Display allocation does what Google's optimizer does in PMax when your conversion event reads cheap (free trial signup): spray cheap impressions, hope it reallocates. In B2B SaaS, it usually does not.

Two moves: cap the asset group budget for Display heavy variants, and restructure the high converting Search portion into a separate Search campaign you control. Recovers an estimated $1,800/month wasted on low intent Display. Want me to draft the asset group structure?

✦ 02 · What makes Hero different

Five jobs. Five tools you'd
default to. Five gaps Hero fills.

Each row pits a Hero agent against the tool most operators reach for first, shown in the form you'd actually receive it. Each one falls short for B2B SaaS in a different way.

How it fits

Setup once.
Reuse forever.

Connect your Google Ads account, describe your product (Hero Marketer asks the right questions for you), and run your first analysis. Once the product profile is in place, every future ad copy run, keyword research, and landing page draft references it automatically.

You write the product. Hero Marketer translates it into a Google Ads campaign that matches what you built.

Why this exists

Performance Max is tuned for ecommerce. In B2B SaaS, the algorithm makes the wrong allocation by default.

John Selvinraj · 9 years running B2B SaaS Google Ads accounts
Founder, Hero Marketer

Every B2B SaaS PMax audit I have run lands at the same finding: budget reallocated to Display where impressions are cheap and clicks happen, while the Search portion (where the conversions actually live) gets under served. Google's optimizer is doing what it was trained to do, for ecommerce.

Hero Marketer walks Performance Max on a separate track from Search because the structures and the assumptions are different. PMax in B2B SaaS is not bad. It is mis tuned, and tuning it requires the kind of reasoning generic tools refuse to encode.

Questions product led teams ask

What to know before adding Hero to your PLG stack.

6 questions

How do you actually handle Performance Max for a PLG account?

Hero's Investigation Agent walks Performance Max on a separate track from Search because the structures are fundamentally different. For PLG accounts, the agent watches the network breakdown for Display leakage (PMax's most common B2B SaaS failure mode), monitors asset group performance against your conversion economics (trial signups, not ecommerce purchases), and flags when the optimizer is reallocating away from your highest intent placements. You get an alert when Display takes more than the threshold you set, and a recommendation to cap or restructure when the math stops working.

Why not just paste our product description into ChatGPT?

You can, and for a single headline it is fine. The difference is what the model writes from. ChatGPT works from whatever you paste that session. Hero writes from a structured product profile captured once at onboarding (what you sell, who buys it, why they pick you over the incumbent) and reuses it across every ad copy run, keyword cluster, and landing page draft. The output stays consistent with what you actually shipped, and you do not have to describe the product again every time you open a new tab.

Will the agent pause our BOFU intent terms because they look expensive?

No. BOFU terms (Software, Tools, Pricing, App, Versus, Demo) are protected by default. The agent only recommends trimming when three independent signals confirm it: high cost, zero conversions, AND a clear semantic mismatch in the search term report. Never on CPC alone. That defaulted protection is one of the explicit ways Hero's reasoning departs from generic Google Ads advice.

Does Hero understand free trial activation windows?

Yes. Sales cycle aware reasoning is baked into every recommendation. The agent will not make a confident call from only 3 days of data when your free trial to paid signal takes 7 to 14 days. If you ask 'is this campaign working?' two days after launching, the answer is 'not enough signal yet' with a date for when there will be, not a confident guess that's noise.

How does this fit with our existing analytics stack?

Hero reads from Google Ads directly via the API. We do not require you to wire up a separate analytics stack to get value. If you have CRM integrated conversion tracking already in Google Ads (offline conversions, enhanced conversions), the agent uses it. If you do not, the agent uses leading indicators (CPL, trial signup rate, demo bookings) and tells you honestly which calls it can and cannot make.

Can the product team and the marketing team both use Hero?

Yes. The work lives in one account, and your product context is captured once and persists, so the product team's setup powers the marketing team's runs. You're billed by credits for the AI work the system does, not per seat. Hero Marketer doesn't have separate per user seats or roles today, so a team works from the shared account rather than each person having their own login.
