Google Search leads cost this San Francisco firm $248 each. It needed a second channel that could add consultations without adding cost. WKND reviewed advertiser eligibility and the firm’s service area before launch, ran ChatGPT Ads next to Google Search for a same-period comparison, and judged the result on intake quality and retained clients, not lead cost alone. From June 15 to July 31, 2026, $11,982 in ChatGPT Ads spend produced 114 leads at $105.11 each. The same spend at Google Search’s $248 CPL buys about 48 leads, so ChatGPT Ads delivered about 66 more. Clicks averaged about $2.62, against an implied $43 on Google, about 16x cheaper. ChatGPT’s click-to-lead rate was lower (2.49% vs 17.43%), and the cheaper clicks more than covered it.

What the San Francisco law-firm test measured

The firm needed a second channel that could add consultations without adding cost. WKND reviewed advertiser eligibility and the firm’s service area before launch, then ran ChatGPT Ads beside Google Search.

From June 15 to July 31, 2026, $11,982 in ChatGPT Ads spend produced 114 leads:

  • Cost per lead: $105.11, against $248 on Google Search
  • Cost per click: about $2.62, against an implied $43 on Google
  • Click-to-lead rate: 2.49% on ChatGPT, 17.43% on Google
  • The same spend at Google’s cost per lead buys about 48 leads, so ChatGPT Ads produced about 66 more

The cheaper clicks more than covered the lower click-to-lead rate. The result belongs to one firm in one market, and the firm remains anonymous.

Why San Francisco is a useful market to test

The firm paid $248 per lead on Google Search and wanted a second channel that would not add cost. Businesses whose Google leads already cost little have a smaller gap to compare.

San Francisco is also compact, about seven miles by seven, and varied. Financial District offices, SoMa start-ups, Mission restaurants and Marina clinics sit a short ride apart but serve very different customers. A single "San Francisco" ad group hides that.

ZIP groups for San Francisco

  • 94104 and 94111: Financial District
  • 94103 and 94107: SoMa and Potrero
  • 94110: Mission
  • 94123: Marina
  • 94115: Pacific Heights and Western Addition
  • Peninsula and Palo Alto: 94301 and neighboring ZIPs

San Jose and Oakland have their own WKND pages, and each can sit as separate ad groups in the same account. A firm that serves the entire Bay Area can use the San Francisco–Oakland–San Jose DMA instead.

Who should test in San Francisco, and who should not

The law-firm case involved a high-value customer, an expensive Google Search lead and a team able to qualify inquiries quickly. Professional services, specialty clinics and B2B software can share those traits.

Software and ecommerce companies headquartered in San Francisco have a second option. They can run state or national campaigns, because buyers are not limited to the city. That is a different test from a local one, with different landing pages.

Wait if your Google Search leads are already cheap, if you have no way to track a call or booking, or if regulated-category eligibility is unresolved.

How the test ran next to Google Search

The law-firm test used a side-by-side design:

  • Google Search and ChatGPT Ads ran for the same weeks
  • Results were read against intake quality and retained clients
  • Cost per lead and click-to-lead rate were compared together

Lead cost alone can mislead: the click-to-lead rate was 2.49% on ChatGPT against 17.43% on Google. Cost per qualified consultation and cost per signed client give a fuller comparison.

Budget for a first San Francisco test

The self-serve minimum is $25 per day, about $750 over 30 days. OpenAI recommends starting CPC bids of $3 to $5, so that is only 150 to 250 clicks a month. The law-firm test spent $11,982 across 47 days, which shows the scale needed to read cost per lead. Your figure depends on your average customer value and capacity. Ad spend is separate from WKND’s program fee.
