One script tag captures the Google click ID from every form submission. Mark leads as converted, enter the deal value, and download a ready-to-upload offline conversion CSV — exactly the format Google Ads expects.
No developer. No GTM. No spreadsheet gymnastics. Just paste one line of code and your Google Ads offline conversions are handled automatically.
| Click ID | Conv. | Time | Val. | Cur. | User Data | Person. |
| Lead | 2026-04-11 09:14 | 2400 | USD | granted | granted | |
| Lead | 2026-04-10 14:07 | 1800 | USD | denied | denied |
When someone clicks your Google Ad and fills out a form, the URL contains a gclid. OCT reads it automatically. Here's exactly what happens:
The gclid is Google's unique identifier for that ad click. OCT reads it from the URL the moment the page loads and holds it in memory ready to attach to any form submission.
| Google Click ID | Conv. Name | Conversion Time | Value | Currency | Ad User Data | Ad Person. |
| Lead | 2026-04-11 09:14:32 +0000 | 2400 | USD | granted | granted |
Upload this CSV in Google Ads → Tools → Conversions → Upload. Google matches the gclid to the original ad click and credits the conversion to the right campaign, ad group, and keyword.
No per-lead fees. No usage caps. All plans include unlimited leads — just pick how many projects you need. 7-day free trial, card required.

"Took me literally 3 minutes to set up. Now I know exactly which Google Ads campaigns are bringing in paying customers — not just clicks."
"I was paying $45/month for CallRail and barely using half the features. OCT does exactly what I need for a fraction of the price."
"I manage 8 client accounts. The agency plan is a steal. My clients love seeing actual revenue tied back to their Google Ads spend — not just lead counts."
"The CSV export goes straight into Google Ads with zero editing. I used to spend an hour every week doing this manually in spreadsheets."
"Finally a tool that doesn't require a developer. I installed it on my Webflow site in 5 minutes flat. The Google Ads import works perfectly."
"The unlimited leads on every plan is what got me. Other tools charge per lead — that adds up fast when you're running high-volume Google Ads campaigns."
OCT was born out of frustration. We were running Google Ads for small businesses and spending hours every week manually matching form submissions to gclids in spreadsheets before uploading offline conversions.
We built the tool we wished existed — purpose-built for Google Ads offline conversion tracking, simple enough that anyone can set it up in 5 minutes, and priced fairly for the businesses that need it most.
