LimeCall + Google Ads:
Close the Loop on PPC Calls
Connect LimeCall to Google Ads to track which campaigns drive callbacks, import offline conversions back to your account, and let Smart Bidding optimise for calls that actually convert.
From £42 to £18 cost-per-call in 90 days
A B2B SaaS company connected LimeCall to Google Ads and enabled offline call conversion import. After 90 days of Smart Bidding optimising against real call outcomes, cost-per-call dropped from £42 to £18 — a 57% reduction — while call quality improved as Smart Bidding shifted budget toward higher-converting keywords.

Everything the LimeCall + Google Ads integration does
Six capabilities that connect your PPC spend to phone revenue.
Dynamic number insertion per campaign and ad group
LimeCall automatically displays a unique tracking phone number to visitors from each Google Ads campaign and ad group. Calls are attributed to the exact campaign, ad group, and keyword — giving you cost-per-call data at every level of your account.
Import call conversions back to Google Ads
When a call converts, LimeCall sends the GCLID and outcome back to Google Ads via the Offline Conversions API. Google attributes the conversion to the originating click, enabling accurate conversion reporting without last-click guesswork.
Smart Bidding optimised for phone leads
Once call conversions flow into Google Ads, Target CPA and Target ROAS Smart Bidding strategies can optimise specifically for calls that convert — not just form fills. Bids increase for queries that historically drive high-value phone leads.
UTM parameter capture on every call
LimeCall captures utm_source, utm_medium, utm_campaign, utm_term, and utm_content from every visitor session. All UTM data is stored against the call record and available in LimeCall reports and any CRM or BI tool you connect.
Cost-per-call reporting by keyword
Combine Google Ads spend data with LimeCall call volume by keyword to calculate true cost-per-call at keyword level. Identify which keywords drive the most callbacks and which drive the highest-quality conversations.
GCLID sync for complete attribution
LimeCall stores the GCLID from every Google click. When the call outcome is logged — even hours or days later — the GCLID is included in the conversion import, ensuring Google Ads receives accurate attribution data with no drop-off.
Who uses LimeCall + Google Ads and how
Prove phone revenue from your Google Ads spend
Stop reporting on click-throughs and form fills. Feed call conversion data back into Google Ads and show the actual revenue generated by PPC campaigns that drive phone traffic — the hardest metric to prove without call tracking.
Let Smart Bidding optimise for real call conversions
Smart Bidding learns from conversion signals. By importing call outcomes — not just call connections — Google Ads bids more aggressively on search queries that drive demo bookings and qualified conversations, not just calls that last 10 seconds.
Cost-per-acquisition by keyword, not just by campaign
LimeCall's keyword-level call attribution lets you calculate a true CPA for phone leads by keyword. Cut spend on keywords that generate high call volume but low conversion rates; scale keywords where calls convert.
Close the loop on high-value PPC phone leads
B2B buyers rarely convert on the first visit. LimeCall captures the GCLID at the first click, stores it across sessions, and sends it to Google Ads when the call happens weeks later — giving you attribution across a long B2B buying cycle.

Frequently asked questions
Does the LimeCall Google Ads integration work with Performance Max campaigns? +
Yes. LimeCall captures the GCLID (Google Click ID) from all campaign types, including Performance Max, Search, Display, and Shopping. Offline call conversions are imported back to Google Ads using the standard Offline Conversions API, which Performance Max campaigns read and optimise against in the same way as other campaign types.
How are offline call conversions imported into Google Ads? +
When a visitor clicks a Google Ad and then requests a callback, LimeCall captures and stores the GCLID from their session. When the call is completed and the outcome is logged, LimeCall automatically sends the conversion event — with the original GCLID, conversion time, and optional conversion value — to Google Ads via the Offline Conversions API. Google Ads attributes the conversion to the originating click, campaign, ad group, and keyword.
Does LimeCall replace Google call extensions or call ads? +
No. LimeCall complements Google call extensions and call ads rather than replacing them. Google call extensions and call ads measure clicks-to-call directly from the SERP. LimeCall tracks callback requests from your website — visitors who click through from an ad and then request a call via the LimeCall widget. Both measurement methods feed conversion data back to Google Ads for a complete picture of phone-driven revenue.
How does dynamic number insertion work with Google Ads? +
LimeCall's dynamic number insertion (DNI) assigns a unique tracking number to each Google Ads campaign or ad group. When a visitor arrives from a specific campaign, LimeCall replaces any phone numbers on the page with the campaign-specific tracking number. Calls to that number are attributed to the correct campaign, ad group, and keyword automatically — even if the visitor later navigates to other pages on your site.
How long does it take for call conversions to appear in Google Ads? +
LimeCall sends the conversion event to Google Ads within minutes of the call outcome being logged. Google typically processes and attributes the conversion within 3–6 hours, after which it appears in your Google Ads conversion reports and is factored into Smart Bidding decisions.
Can I set a conversion value for phone calls in Google Ads? +
Yes. LimeCall lets you assign a monetary conversion value to different call outcomes — for example, a completed demo call might carry a £150 value based on your average close rate and deal size. You can also pass dynamic conversion values if you capture deal size or product selection through the LimeCall widget form. These values inform Target ROAS bidding in Google Ads.
Does LimeCall capture UTM parameters for non-Google Ads traffic too? +
Yes. LimeCall captures all UTM parameters — utm_source, utm_medium, utm_campaign, utm_term, and utm_content — from every visitor session, regardless of the traffic source. This means you can attribute phone conversions to Google Ads, Microsoft Ads, Meta, email campaigns, and any other UTM-tagged traffic source within a single LimeCall reporting dashboard.
