Remarketing vs retargeting: what is the difference and when do you use which in B2B?

Remarketing vs retargeting: most people mean the same thing by both terms.

Both are about reaching people again who already know your brand, or who were close to finding you.

The verdict: retargeting usually means paid ads based on behaviour, remarketing a broader mix that includes email. What really moves your results isn’t the term, it’s the type you pick.

There are four types: site, search, CRM and email retargeting.

Each one works on a different data source and fits a different moment in a B2B buying cycle.

Is there really a difference between remarketing and retargeting?

Technically not much.

The terms have become largely interchangeable, and nobody owns a strict definition.

How the platforms use the words

Google used “remarketing” for years.

Its help pages now say “remarketing” is referred to as “your data” (About your data segments).

Many other ad platforms say “retargeting”. Marketers happily switch between the two.

The nuance that keeps coming back

There’s one nuance that does keep showing up. Search Engine Journal explains it clearly in its comparison of remarketing and retargeting:

• Retargeting: paid ads based on earlier behaviour, such as a website visit or a search.
• Remarketing: a broader umbrella, including email campaigns and reactivating your own contacts.

SEJ sums up retargeting as “moving not-yet customers down the purchase path”. Remarketing leans more towards people who already bought.

Here’s the difference between remarketing and retargeting side by side:

What matters more than the word

For your decisions, that distinction is a side issue.

The question that does matter: which data source do you build a list on, and who do you reach with it?

That decides whether you approach someone you already know, or someone who was looking for your solution but never saw you.

Which types of retargeting exist?

Four: site, search, CRM and email retargeting.

Each one works on a different data source and fits a different moment in your marketing funnel.

Site retargeting

This is the type most people know.

A pixel or tag on your website puts visitors in a list.

You use that list to show them ads later on other sites, on social media or in search results.

Biggest strength: you’re talking to people who already showed interest. Your conversion odds are higher than with cold ads.

Watch out: it only works for people who already visited your site. Anyone who never found you, you won’t reach this way.

The tag differs per platform. On Meta it’s the Meta Pixel; on LinkedIn you build matched audiences.

Here’s where those lists live in Google Ads:

The labels under Audience manager have changed over the years. The logic hasn’t: visitors in, segments out.

Search retargeting

This is where it gets interesting for B2B.

Search retargeting requires no website visit.

Interest is determined by a recent search, for example on Google, Yahoo or Bing (Chango).

For example, say someone searches for “industrial cleaning supplier” but lands on a competitor’s site. With search retargeting you can still reach that person, even though they were never on your site.

Some platforms estimate purchase intent (an “intent score”). They base it on an enormous volume of search events in their data network, in the order of billions of searches (Chango).

For the top of a long B2B sales cycle, that’s gold.

You catch people who are actively searching, before they even know you.

CRM retargeting

With CRM retargeting you upload your own contact database to an ad platform.

That’s email addresses or company data.

The platform matches those contacts and shows ads to them.

In Google Ads that feature is called Customer Match.

Google describes the segment as “customers from your uploaded data file who are Google users” (Customer Match help). It also notes that “Customer Match memberships expire after 540 days”.

Best for: account-based campaigns. You target the decision makers within the companies you want to win, the core of account-based marketing.

Also great for: exclusions. Existing customers and open quotes are often exactly the people you don’t want to hit with the same ads again.

Email retargeting

This is retargeting through your own mailbox.

Someone clicks in a newsletter and views a service page, but doesn’t request anything? A follow-up email or an automated sequence brings that person back.

Price: no ad budget. It reaches people who already have a relationship with you.

Our guide to lead nurturing email flows shows how to build those sequences.

When do you use which type in B2B?

Rarely just one.

In a long B2B sales cycle with several decision makers, you stack them.

The art is to use each one at the right moment.

The four types per scenario

The table below links each type to a concrete scenario:

A typical build-up

A typical stack runs in four layers:

1. Search retargeting attracts new, searching prospects.
2. Site retargeting keeps visitors warm during the months-long decision period.
3. CRM retargeting reinforces the campaign on your target accounts.
4. Email retargeting catches the people who were already very close.

Here’s that stack as a funnel:

For the broader context of paid channels, read our overview of online advertising. For search ads specifically, see remarketing with RLSA.

RLSA brings your lists into Google’s Search Network, so you can bid differently when a past visitor searches again.

Rule of thumb: start with the layer closest to the deal, then add the next one up.

How do you avoid brand fatigue with frequency capping?

By setting a limit on how often one person sees your ad.

The biggest risk of retargeting is irritation.

If someone sees your ad ten times a day, you create resistance instead of trust.

In a long B2B cycle, where you want to stay visible for months, that’s a real danger.

What a sensible frequency cap looks like

Frequency capping is a limit on how often someone sees your ad.

A commonly used guideline sits around 17 to 20 impressions per month, to prevent prospects from getting annoyed (ReTargeter).

Treat that as a starting point, not as law.

For a complex service with a high order value, exposure may be higher than for a simple enquiry.

Where you can set it in Google Ads

Not every campaign type lets you cap it. Google’s frequency capping help says:

• Display campaigns: automatic or manual caps, counting only viewable impressions.
• Video campaigns: caps per day, week or month, on campaign level.
• Demand Gen: “Frequency capping isn’t supported in Demand Gen campaigns.”

Four rules of thumb we apply

These keep a list fresh instead of irritating:

• Cap the frequency per person and per period, not just per campaign.
• Rotate your messages so people see variation, not endless repetition.
• Exclude converters: customers and recent enquirers don’t belong in your list.
• Put an end date on your lists so you don’t pay for long-gone visitors.

Social platforms need the same discipline. Our guide to B2B retargeting on social ads covers LinkedIn and Meta.

Is retargeting actually worth it for your business?

Not always, and we’d rather say so upfront.

Why ecommerce numbers mislead B2B

Retargeting platforms claim impressive returns.

Some even talk about a multiple of their clients’ ad spend coming back as revenue (AdRoll).

But such figures usually come from ecommerce, where the purchase happens fast and on impulse. In B2B it’s different.

A long sales cycle means months between first click and signed deal.

Three conditions before you start

Retargeting is worth it for you if:

• you have enough website traffic or contacts to fill a workable list
• your sales cycle is long enough for repeated contact to add something
• you steer on qualified enquiries and revenue, not on click-through rates

Click-through rates always look good in retargeting, simply because you’re talking to warm people. That says little about whether real leads come out of it.

Steer on enquiries, not clicks

So tell the platform what a real enquiry is. In Google Ads that means a primary conversion action for the form:

The contact form conversion action in our own Google Ads account, October 2026. It’s set as primary, so campaigns optimise on real enquiries, not clicks.

Then judge each list on qualified leads and ROAS measured the B2B way.

When to wait

Barely any traffic and no list worth mentioning?

Then invest in attracting the right visitors first.

A high return on an empty list doesn’t exist.

How we look at such a choice, you can read in our approach to paid advertising.

Frequently asked questions about remarketing and retargeting

Is remarketing the same as retargeting?

In practice the terms are used interchangeably and people usually mean the same thing by them. When a distinction is made, retargeting more often refers to paid ads based on behaviour, and remarketing to a broader mix including email. For your results, what mainly counts is which type you use, not which term you use.

What is the difference between site retargeting and search retargeting?

Site retargeting reaches people who already visited your website, via a pixel or tag. Search retargeting works without a website visit: it targets people based on their recent searches. Search retargeting is therefore suitable for finding new prospects who don’t know you yet, while site retargeting keeps existing visitors warm.

Does retargeting also work for B2B with a long sales cycle?

Yes, provided you approach it differently than ecommerce. You keep people warm for months instead of days, you target multiple decision makers within an account, and you lead with content instead of direct offers. Combine types and steer on qualified enquiries.

How often may someone see my retargeting ad?

A common guideline sits around 17 to 20 impressions per month per person, but adapt it to your context. For a complex, high-value service the frequency may be higher, for a simple enquiry lower. Always set a cap to avoid brand fatigue.

Getting started with retargeting that delivers leads

The remarketing vs retargeting debate matters less than which type you use, for whom, and when.

Combine search, site, CRM and email retargeting deliberately. Cap the frequency, and judge every list on qualified enquiries.
