E-commerce or Lead Generation: Two Different Google Ads Strategies
Key takeaways
- E-commerce: the conversion is a sale of known value; leads: a contact whose value shows in the CRM.
- E-commerce: product feed, value-based bidding, margin rather than revenue, new customers.
- Leads: intent, every lead tracked, qualification sent back to Google, values by stage.
- Every tracked lead becomes an audience: your data segments and Customer Match, with consent.
- Lead nurturing: messages by stage (discovery, consideration, decision) and signed customers excluded.
An online shop and a business generating leads use the same Google Ads, but not the same strategy. In the first case the conversion is a sale, with a value known at the moment of the click. In the second it is a contact (form, call, quote request) whose value only shows weeks later, in the CRM.
That difference changes everything: what you measure, the bid strategy, the campaigns, and how you judge profitability. This article compares the two approaches, then explains why, in lead generation, tracking every lead is also the foundation of remarketing and lead nurturing programmes.
What changes: the conversion and its value
| E-commerce | Lead generation | |
|---|---|---|
| Conversion | A purchase | A form, a call, a quote, a sign-up |
| Value | Known immediately (basket value) | Unknown at first: depends on qualification and signing |
| Delay | Short: minutes or days | Long: weeks or months in B2B |
| Key data | The product feed | The CRM |
| Typical bidding | Maximise conversion value, Target ROAS | Maximise conversions, Target CPA, then value on qualified leads |
| Profitability metric | Margin, ROAS | Cost per qualified lead, cost per customer |
Automated bidding optimises what it is shown (About Smart Bidding, Google FAQ). In e-commerce it sees revenue; in lead generation it only sees contacts, until qualification is sent back from the CRM.
The e-commerce strategy: manage value, not volume
- The product feed at the centre: Shopping and Performance Max rely on Merchant Center. Titles, prices, availability and images drive half the performance.
- Value-based bidding: Maximise conversion value, then Target ROAS; Google recommends differentiated conversion values for these strategies (Value-based Bidding Best Practices, Google FAQ).
- Margin rather than revenue: two products at the same price are not equally profitable. Value rules adjust some conversions’ value by audience, location or device (About conversion value rules, Google FAQ).
- New customers: the new customer acquisition goal lets you bid more for people who have never bought (About customer lifecycle goals, Google FAQ).
- Seasonality: sales, Black Friday and holidays concentrate a large share of revenue (see our Black Friday and sales article).
The lead generation strategy: manage quality
- Intent before volume: solution and evaluation queries (« quote », « pricing », « provider »), negative keywords from day one.
- Every lead tracked: forms, calls from ads and from the website (About phone call conversion tracking, Google FAQ), downloads, sign-ups, with primary and secondary conversions (About primary and secondary conversion actions, Google FAQ).
- Qualification sent back to Google: offline conversion import (About offline conversion imports, Google FAQ) or enhanced conversions for leads (About enhanced conversions for leads, Google FAQ), so bidding targets the leads that become customers.
- Values by stage: without a basket value, proxy values (a higher value for a qualified lead than for a download, for example) enable value-based bidding (Value-based Bidding Best Practices, Google FAQ).
Detailed method: track every lead, calls included and cost per lead.
Tracking leads for remarketing and lead nurturing
A tracked lead is not just a measurement. It is also an audience: someone who showed interest, whom you can accompany to a decision. This is where lead generation meets relationship marketing.
Building audiences from leads
- Your data segments: visitors who downloaded a guide, viewed the pricing page or started a form become segments you can reuse in campaigns (About your data segments, Google FAQ).
- Customer Match: CRM contacts you collected yourself, with consent, can be uploaded to reach those people on Google, YouTube and Gmail (About Customer Match, Google FAQ), within Google’s rules (Customer Match policy, Google FAQ).
- Lists by stage: a « download » lead, a « quote sent » lead and a customer need different messages. CRM statuses sent back to Google let you separate them.
A lead nurturing programme
Lead nurturing means maturing a contact who is not yet ready to buy. A simple scheme:
- Discovery: a download or sign-up, tracked as secondary conversions.
- Consideration: Demand Gen or YouTube ads show case studies, demos and testimonials to leads at that stage only (About Demand Gen campaigns, Google FAQ); email takes over outside Google.
- Decision: a meeting or quote offer, and a quick call-back from sales.
- Exclusion: signed customers leave acquisition campaigns, so you don’t pay for useless clicks.
Without lead tracking none of this is possible: you can neither target, nor exclude, nor measure what moves a prospect forward.
What about mixed models?
Many businesses combine both: a B2B shop that sells online but receives quote requests for large volumes, a manufacturer selling to consumers and generating reseller leads. In that case, separate campaigns by goal, track both conversion types, and give each a consistent value so bidding can arbitrate between a sale and a lead.
Conclusion
E-commerce is managed on value and margin, with the product feed at the centre. Lead generation is managed on quality, with the CRM at the centre. In both cases the rule is the same: show Google the real value of each conversion. And in lead generation, every tracked lead becomes an audience to accompany to the sale.
