# What is Retargeting? Retargeting vs Prospecting Explained

> Retargeting shows ads to people who already visited your site or engaged with your content. Learn when to retarget and how to segment.

**Retargeting** is showing ads to people who have already interacted with your business. They visited your website, watched your video, added something to their cart, or engaged with a previous ad. Instead of reaching cold strangers, you're re-engaging warm audiences who already know who you are. Retargeting typically produces higher conversion rates and lower [CPA](/learn/cpa) than prospecting because the audience has already shown interest.

## What are the different types of retargeting?

| Type                      | Audience Source                                                                                    | Best For                                  |
| ------------------------- | -------------------------------------------------------------------------------------------------- | ----------------------------------------- |
| Website retargeting       | People who visited specific pages on your site (tracked via [Meta Pixel](/learn/meta-pixel))       | E-commerce, lead gen, SaaS                |
| Engagement retargeting    | People who interacted with your Instagram/Facebook content, watched a video, or opened a lead form | Building warm audiences without a website |
| Cart abandonment          | People who added to cart but didn't purchase                                                       | E-commerce (highest-intent retargeting)   |
| Customer list retargeting | Email lists or phone numbers uploaded as [Custom Audiences](/learn/custom-audiences)               | Upsells, cross-sells, re-engagement       |

Website retargeting is the most common type. You install the [Meta Pixel](/learn/meta-pixel) and [Conversions API](/learn/conversions-api) on your site, and Meta builds an audience of everyone who visited in the last 1-180 days. You then show ads only to that group.

## Retargeting in plain English

Imagine you walk into a clothing store, try on a jacket, but leave without buying. The next day, a store clerk shows up at your door holding that exact jacket and says, "Hey, still interested? It's 15% off today." That's retargeting. The store remembered what you looked at and followed up with a relevant offer.

The difference between retargeting and [prospecting](/learn/prospecting) is simple. Prospecting is handing flyers to strangers on the street. Retargeting is following up with people who already walked into your store.

## How does retargeting compare to prospecting?

Retargeting audiences are smaller but convert at much higher rates. Here are typical benchmarks for Meta Ads:

| Metric              | Prospecting (Cold) | Retargeting (Warm) |
| ------------------- | ------------------ | ------------------ |
| [CTR](/learn/ctr)   | 0.8% - 1.5%        | 2% - 5%            |
| Conversion Rate     | 1% - 3%            | 5% - 15%           |
| [CPA](/learn/cpa)   | \$25 - \$80        | \$8 - \$30         |
| [ROAS](/learn/roas) | 1.5x - 3x          | 4x - 10x           |
| [CPM](/learn/cpm)   | \$6 - \$15         | \$10 - \$25        |

<Warning>
  Retargeting ROAS looks inflated because these people were already likely to buy. Don't shift your entire budget to retargeting thinking it will scale. The audience is small and dependent on your prospecting campaigns filling the top of the funnel.
</Warning>

## Common retargeting mistakes

<Accordion title="Retargeting everyone the same way (no segmentation)">
  Someone who viewed your homepage once is very different from someone who added to cart. Showing both the same generic ad wastes money on low-intent visitors and misses the chance to close high-intent ones. Segment by behavior: page viewers get awareness ads, cart abandoners get urgency ads with the product they left behind.
</Accordion>

<Accordion title="Running retargeting windows too long">
  A 180-day retargeting window means you're showing ads to people who visited your site 5 months ago. They've forgotten about you. Cap your retargeting windows at 14-30 days for most businesses. For high-consideration purchases (B2B, luxury), 60 days max. After that, the audience is too cold to convert efficiently.
</Accordion>

<Accordion title="Not excluding people who already converted">
  If someone already bought your product, stop showing them the same "Buy Now" ad. Exclude purchasers from your retargeting audiences. You can create a separate campaign for upsells or cross-sells, but don't burn budget convincing someone to buy something they already own.
</Accordion>

<Accordion title="Using the same creative as prospecting">
  Your prospecting ads introduce your brand. Your retargeting ads should acknowledge the relationship. Someone who already visited your pricing page doesn't need a "Who We Are" video. They need a testimonial, a discount code, or a reminder of what they were looking at. Match the creative to the stage.
</Accordion>

<Accordion title="Ignoring frequency caps">
  Retargeting audiences are small. Without [frequency](/learn/frequency) controls, the same 500 people see your ad 15 times in a week. That's not persuasion, that's annoyance. It leads to [ad fatigue](/learn/ad-fatigue), negative feedback, and wasted spend. Monitor frequency and rotate creatives when it climbs above 4-5 per week.
</Accordion>

## How retargeting relates to other concepts

| Concept                                     | Relationship                                                                                                                                               |
| ------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [Custom Audiences](/learn/custom-audiences) | Retargeting audiences are built as Custom Audiences in Meta Ads. Website visitors, video viewers, and customer lists are all Custom Audience types.        |
| [Meta Pixel](/learn/meta-pixel)             | The Pixel tracks website visitors and their actions, providing the data to build website retargeting audiences.                                            |
| [Conversions API](/learn/conversions-api)   | Server-side tracking that supplements the Pixel. Improves retargeting audience accuracy, especially with iOS 14+ privacy changes.                          |
| [Prospecting](/learn/prospecting)           | The opposite of retargeting. Prospecting fills the top of the funnel with new visitors. Retargeting converts those visitors into customers. You need both. |
| [Frequency](/learn/frequency)               | Small retargeting audiences can lead to very high frequency. Monitor it closely to avoid ad fatigue.                                                       |
| [Ad Fatigue](/learn/ad-fatigue)             | When your retargeting audience sees the same ad too many times, performance drops. Rotate creatives every 1-2 weeks.                                       |

## Steps for effective retargeting

<Steps>
  <Step title="Install tracking properly">
    Set up [Meta Pixel](/learn/meta-pixel) and [Conversions API](/learn/conversions-api) on your site. Verify events are firing for PageView, ViewContent, AddToCart, and Purchase. Without accurate tracking, your retargeting audiences will be incomplete.
  </Step>

  <Step title="Segment by intent level">
    Create separate audiences based on behavior. A 3-tier approach works well: all website visitors (low intent), product page viewers (medium intent), and cart abandoners (high intent). Each tier gets different messaging and offers.
  </Step>

  <Step title="Set appropriate time windows">
    Use 7-day windows for cart abandoners (they're deciding now), 14-day windows for product viewers, and 30-day windows for general site visitors. Shorter windows mean higher intent but smaller audiences.
  </Step>

  <Step title="Exclude converters">
    Always exclude people who already completed the action you're optimizing for. Create a Purchase Custom Audience and add it as an exclusion in every retargeting ad set.
  </Step>

  <Step title="Create stage-specific creative">
    Cart abandoners should see the exact product they left behind with a clear call to action. Product viewers should see social proof and benefits. General visitors should see your strongest offer or bestsellers.
  </Step>

  <Step title="Monitor frequency and rotate">
    Check [frequency](/learn/frequency) weekly. When it passes 4-5 in a 7-day window, swap in new creatives. Keep 2-3 variations ready so you can rotate without pausing campaigns.
  </Step>

  <Step title="Balance budget between prospecting and retargeting">
    Most businesses should spend 70-80% of budget on prospecting and 20-30% on retargeting. If you spend too much on retargeting, you'll exhaust the audience. If you spend too little, you're leaving easy conversions on the table.
  </Step>
</Steps>
