Every Google Ads account has waste. The question is where. The Google Ads interface makes finding it genuinely difficult: different reports for keywords, search terms, ad variations, assets, and placements, each with their own filters and date ranges. A thorough audit takes half a day. Most operators skip it.
Connecting Google Ads to Claude through CorpusIQ compresses that half-day into a conversation. Ask where the waste is, Claude pulls from the Google Ads API, and the underperformers surface in minutes.
The problem with the current workflow
Google Ads' UI is built for buyers who live in it. If you are managing a $20k/month spend as one of ten things on your plate, the interface punishes you. Keyword performance here, search terms there, asset reports in a third place, placements in a fourth. Each one is a filter-sort-export ritual.
Agencies fill this gap, but agency reports tend to focus on what the agency wants to highlight. The campaigns that are working get prominent placement. The campaigns that are bleeding money get a footnote. The question "where is my waste" is not the question agency reports are designed to answer.
Doing it yourself requires fluency in the Google Ads Editor or API. Most operators do not have that fluency. The result is wasted spend that stays wasted for months.
How CorpusIQ solves it
CorpusIQ connects Google Ads to Claude through MCP. Claude can query campaigns, ad groups, keywords, ads, search terms, audiences, assets, and performance metrics across any account or MCC you grant access to.
Read-only access. CorpusIQ requests only the read scope. Claude cannot pause campaigns, adjust bids, modify budgets, or make any structural change to your account. It surfaces what is happening. You decide what to do.
Live queries. Every question hits the Google Ads API in real time. No caching, no delayed reports, no stale data.
Revoke instantly. Disconnect from the Google account permissions page and access is gone.
What you can actually do
- "Which keywords have spent more than $500 this month with zero conversions?"
- "Show me the top 20 search terms triggering my ads that I have not added as exact match or negatives."
- "List campaigns where CPA is more than 50 percent above the account average."
- "Which ad groups have impressions but no clicks in the last 14 days?"
- "Compare this month's CTR to last month, broken down by campaign."
- "What is my cost per conversion on brand terms versus non-brand terms?"
- "Show me every ad variation with a quality score below 5."
- "Which geo locations are converting below the account average but getting more than 10 percent of the spend?"
Follow-ups are natural. Ask about wasted spend, drill into the top offender, then ask what search terms are driving that spend. Three questions, concrete audit findings.

First question is live.
Where this earns its keep
The operators who get the most value from this are the ones managing Google Ads themselves or supervising an agency. If you run your own ads, Claude replaces the audit you keep meaning to do. If you work with an agency, Claude gives you an independent view of what is happening in the account so you can ask sharper questions during QBRs.
It stacks well with GA4, Shopify, and Klaviyo. Ask Claude about wasted Google Ads spend, then ask which landing pages those ads sent traffic to, then ask whether any of that traffic converted downstream. The cross-source view is where the real analysis lives.
It also helps with attribution sanity checks. If Google Ads says a campaign drove 50 conversions but Shopify and GA4 tell a different story, you can surface the gap in one question. The discrepancy is the signal.
What to watch out for
Three honest caveats.
First, Claude will not replace a senior PPC manager for strategy. It is excellent at surfacing problems and asking sharper questions. It is not a substitute for someone who knows when to shift from Manual CPC to Target CPA, or how to structure a PMax campaign correctly.
Second, Performance Max is a black box by Google's design. The API exposes asset-level and campaign-level data, but deep breakdowns by audience or placement inside PMax are limited. Claude returns what Google returns. The ceiling on PMax insight is set by Google, not by CorpusIQ.
Third, attribution is a Google Ads reporting choice. The conversion counts Claude surfaces reflect whatever attribution model you have set. If that model does not match reality, the answers will look off. Configure attribution thoughtfully before auditing.

FAQ
Does CorpusIQ store my Google Ads data?
No. Read-only, zero data storage. Every query hits the Google Ads API live.
Can Claude pause campaigns or change bids?
No. CorpusIQ is read-only by design. Claude can surface insights but you execute changes in Google Ads.
Does it support MCC (manager accounts)?
Yes. Connect an MCC and Claude can query across every linked sub-account.
What about Performance Max campaigns?
Supported where Google exposes data. Asset-level insight depth depends on what the Google Ads API returns for PMax.
