Dynamic remarketing shows past visitors ads for the exact items they viewed, assembled automatically from a feed. It was built for catalogues — retail products, hotels, jobs, listings — and needs a feed plus a Google tag that passes item IDs. Most B2B SaaS companies sell three or four plans, so there is little for it to personalise. A stage-based remarketing strategy (pricing-page visitors, demo abandoners, stalled trials, closed-lost deals) almost always does more for pipeline. The exception is SaaS with a large browsable catalogue, covered below.
How Google Ads dynamic remarketing works
- A feed lists your items, each with an ID, name, image, URL and usually a price. Retailers use Merchant Center; other business types upload a feed in Google Ads (check which feed types your account currently supports).
- The Google tag records which items each visitor viewed, by sending the item ID and page type on every product, listing or detail page.
- Responsive display ads pull the matching items from the feed for each person, so someone who viewed three listings sees those three listings.
If the IDs in the tag don't match the IDs in the feed, the ads quietly fall back to generic creative, and you are running standard remarketing with extra setup.
Does dynamic remarketing fit a SaaS business?
| Your product | Dynamic remarketing? | Why |
|---|---|---|
| Sales-led B2B SaaS with a few plans | No | No catalogue to personalise; the returning buyer needs proof, not a product reminder |
| PLG product with a template gallery or library | Possibly | Visitors view specific templates; showing those back can pull them into a signup |
| Integration directory or app marketplace | Possibly | Each integration page is an item; useful if integration pages drive signups |
| Vertical SaaS with listings (jobs, property, venues) | Yes, for the listing side | A real catalogue with item-level intent |
If you're in the first row, which most funded B2B SaaS companies are, skip the feed work and put the effort into the segments below.
A SaaS remarketing strategy that builds pipeline
Organise remarketing by how close each person is to a sales conversation, not by which page they saw. Each segment gets its own message and its own exclusions:
| Segment | What to show them | Where |
|---|---|---|
| Pricing-page visitors who didn't convert | Proof for your deal size: a case study, ROI numbers, security answers | Search (RLSA) on category terms, YouTube, Demand Gen |
| Demo-form abandoners | A shorter path: book a slot directly, or a recorded demo | Search (RLSA), Demand Gen |
| Trial users who didn't activate | The one action that predicts conversion, plus an offer of onboarding help | Customer Match from product data, YouTube |
| Closed-lost opportunities | What changed since: new features, pricing, a competitor comparison | Customer Match from the CRM |
| Customers and open opportunities | Nothing — exclude them | Exclusion lists on every campaign |
On Search, these lists are most useful as RLSA signals: bid harder on broad category terms when the searcher has already been to your pricing page. Audience setup and the size thresholds lists need before they serve are covered in audience targeting for B2B SaaS and the 100-user audience minimum.

Measure remarketing on pipeline, with a holdout
Remarketing reaches people who already know you, so it always looks efficient in the platform. View-through conversions and data-driven credit for the last ad seen make it worse. Three rules keep it honest:
- Judge it on SQLs and opportunities imported from the CRM, not on view-through conversions or cost per lead.
- Run a holdout once a quarter: exclude a random share of each list for a few weeks and compare SQL rates between exposed and held-out visitors.
- Keep the budget proportionate. Remarketing can only convert demand you already created; if it is a large share of spend, the account is short of new demand, not short of reminders.
The broader case for incrementality testing in B2B SaaS is in conversion lift for Search and PMax.
