Guide · Channel choice
Don’t pick by cost per click or cost per lead. Pick by where your buyers’ demand already exists, then compare the platforms on cost per qualified lead and on how quickly each can learn from your CRM.
Short answer
Google Ads usually wins when buyers already search for your product or problem, because the lead arrives with intent. Meta works better for creating demand, retargeting and visual proof, and its leads usually need stronger qualification. Compare both on cost per qualified lead or opportunity, not cost per click or cost per lead.
A Google Search lead typed something like “hydraulic cylinder manufacturer Pune” or “SOC 2 compliance software”. The need already exists; your ad competes to be the answer. A Meta lead was scrolling, saw your ad, and responded. Meta can reach the right people, but most of them weren’t looking for you that day.
That difference should shape everything downstream:
| In B2B | Google Search | Meta (Facebook and Instagram) |
|---|---|---|
| Buyer state | Problem-aware, often comparing suppliers | Not searching; may be problem-aware |
| Best offer | RFQ, quote, demo, consultation | A guide, webinar, specification sheet or lower-commitment call |
| Form design | Short form; intent is already there | Qualifying questions and a Higher intent Instant Form, or a website form |
| Main limit | Search volume for your category | Qualification; small audiences in niche markets |
| Typical role | Lead channel for searched categories | Demand creation, retargeting, event follow-up |
The gating test is simple: do people search for your category or problem in the markets you sell to? Check it in Google’s Keyword Planner before deciding. If a niche industrial term shows almost no searches, Google can’t be the lead channel however well it is managed. Meta, LinkedIn or marketplaces then carry more of the load.
Worked numbers
Short answer
Per lead, often. Per qualified lead, it depends. Meta leads can cost a fraction of Google leads and still cost more once you divide by the leads sales accepts. Work out cost per qualified lead for each platform and each conversion route, using the same qualification rule, before moving any budget between them.
| Route | Spend | Leads | Cost per lead | Qualified | Cost per qualified lead |
|---|---|---|---|---|---|
| Google Search, website RFQ form | ₹1,80,000 | 200 | ₹900 | 90 (45%) | ₹2,000 |
| Meta, Instant Form | ₹75,000 | 300 | ₹250 | 18 (6%) | about ₹4,167 |
| Meta, website RFQ form | ₹44,000 | 40 | ₹1,100 | 10 (25%) | ₹4,400 |
Meta’s Instant Form leads look almost four times cheaper than Google’s, but each qualified lead costs about twice as much. Google is the lead channel here. Meta’s job is to retarget specification-page visitors and follow up after trade shows, judged on how those people progress; see B2B retargeting on Meta.
Google: $12,600 for 30 sales-qualified leads ($420 each) and 9 opportunities ($1,400 each). Meta, with a Higher intent form and a webinar offer: $11,400 for 30 SQLs ($380 each) but 6 opportunities ($1,900 each). Meta wins on cost per SQL and loses on cost per opportunity, so the deeper stage decides.
A Dubai ISO certification consultancy finds steady searches for its services, and a small reachable audience on Meta. Google captures the enquiries; Meta runs short video from the founders to past visitors and event contacts, and is judged on whether those contacts request consultations.
How to calculate cost per qualified lead consistently is in cost per qualified lead.
Short answer
Google accepts qualified stages as offline conversions or enhanced conversions for leads, now uploaded through the Data Manager API. Meta’s Conversion Leads goal learns from CRM stages sent through the Conversions API, but only for Instant Form leads and at least 200 leads a month. Which platform can learn from your stages changes the comparison.
| Google Ads | Meta Ads | |
|---|---|---|
| Route | Offline conversion import and enhanced conversions for leads, through the Data Manager API from 15 June 2026 (Google Ads Help) | Conversion Leads with CRM stages sent through the Conversions API (Meta for Developers) |
| Lead source | Website forms and calls, matched by click ID or hashed user data | Instant Forms only |
| Stated requirements | See Google’s guidance in the offline conversion import guide | At least 200 leads a month; a stage reached by 1–40% of leads within 28 days; uploads at least daily |
| What it means for B2B | A website RFQ or demo form can teach bidding which leads qualified | A low-volume account, or one using website forms, can’t use CRM stages for Meta optimisation |
An account with 60 Meta leads a month optimises Meta for leads and has to filter quality with the form and creative. The same account can send qualified stages to Google from day one. That asymmetry is often a reason to lead with Google in a searched category. Details are in Conversion Leads optimisation.
Original framework
Score each platform 1–3 on five criteria. The higher total is your lead platform; the other plays a support role until its qualified-lead numbers earn more budget.
| Criterion | Score 3 when | Fastener maker: Google | Fastener maker: Meta |
|---|---|---|---|
| Existing search demand | Buyers search your category or problem every month | 3 | 1 |
| Visual or demonstrable proof | Your product or result shows well in a short video or image | 1 | 2 |
| Audience reachability | You can reach the buyer: keywords on Google; lists, engagers or broad delivery plus a qualifying form on Meta | 3 | 2 |
| Signal readiness | Enough volume and a route to send qualified stages back | 3 | 1 |
| Sales-cycle role | Fits what the pipeline needs now: capture or nurture | 3 | 2 |
| Total | 13 | 8 |
Short answer
With a limited budget, start with the platform that matches existing demand, usually Google for searched categories. Add Meta once tracking and lead qualification work, first for retargeting and then prospecting, and judge each channel on qualified leads recorded in your CRM or spreadsheet rather than platform-reported conversions.
Running both without double-counting. Meta retargeting often reaches people Google first brought to your site. Both platforms may then report the same lead as their conversion. Settle credit in your CRM: store the original source and the lead’s stage history, and judge each channel on the qualified leads and opportunities it originated or clearly assisted. Paid media pipeline attribution covers the options.
Moving money between the two in flight is its own discipline; see budget velocity.
LinkedIn reaches buyers by job function, seniority and company, which neither Google nor Meta does as directly. It usually costs more per lead and can still cost less per opportunity, especially for SaaS and professional services selling to committees. The comparison is in Google vs LinkedIn Ads for B2B.
Zephra creates and manages campaigns on Google, Meta and LinkedIn using lead quality from CRM data or a spreadsheet, and allocates budget within your approvals and spend boundaries. See Google Ads and Meta Ads for B2B.
Questions, answered
Meta reaches people who weren’t searching, and Instant Forms make submitting easy, so more leads are low intent. That gap isn’t fixed. Higher intent forms, qualifying questions, offers that match the buying stage, and sending CRM stages back to Meta once volume allows can all narrow it. See Instant Forms lead quality.
Yes, usually in a supporting role: retargeting site visitors, following up trade show contacts, and showing products in use. Prospecting for RFQs on Meta works best with a qualifying form and a clear minimum order or project size.
They measure it differently. Google says bid strategies can take up to around 50 conversion events or 3 conversion cycles to calibrate (Google Ads Help). Meta says ad sets usually leave learning after about 50 results in the week after the last significant edit (Meta Business Help). At B2B volumes, both can take weeks.
Fund the lead platform to cover the demand you can capture, give the support platform a fixed test budget, and move money monthly towards the lower cost per qualified lead or opportunity once each has enough qualified leads to compare.
It can. Each platform reports conversions it touched, so the same lead may appear in both. Use your CRM’s original source and stage history to decide credit.
