The script explains how to choose the best Meta ad conversion event to optimize for. It recommends using the purchase event only when a campaign generates more than 10 purchases per week; otherwise, advertisers should optimize for a higher-funnel event like add to cart or initiate checkout. The speaker argues that, in practice, Meta often performs better with these more frequent events than with underpowered purchase optimization, despite the assumption that purchase and add-to-cart users would convert similarly.

Key Information

  • The speaker is advising on whether a Meta ad campaign should optimize for add-to-cart or purchase conversion events.
  • Meta generally needs at least 50 conversions of the chosen event within a week to fully optimize.
  • A practical rule given is to optimize for purchases if you generate more than 10 purchases per week.
  • If purchases are below that threshold, it is usually better to optimize for a higher-funnel event like add to cart.
  • Optimizing for add to cart does not necessarily produce equally good purchase results because Meta may find users who add items but do not buy.
  • The speaker concludes that the cutoff should be around 10 purchases per week rather than 50.

Timeline Analysis

Meta Ads Campaign Optimization

Explains how to choose the best conversion event for a Meta ad campaign, comparing add-to-cart, initiate checkout, and purchase optimization based on weekly conversion volume.

Purchase Conversion Event

Recommends optimizing for purchases when a campaign generates more than 10 purchases per week, since Meta can better fully optimize with enough purchase data.

Add to Cart Optimization

Suggests using add-to-cart or other higher-funnel conversion events when purchase volume is too low, noting that Meta can still find users likely to buy even if they do not always purchase immediately.

Meta Conversion Threshold

Highlights the idea that Meta wants around 50 conversions of the chosen event within a week for full optimization, but the practical decision threshold for purchases is closer to 10 per week.

Related questions&answers

For a Meta ad campaign, should you optimize for the add to cart conversion event or the purchase conversion event?

It depends on how many conversions you generate each week. Meta needs enough volume to optimize effectively.

How many conversions does Meta need to fully optimize a campaign?

Meta wants at least 50 conversions of the event you are optimizing for within a week to fully optimize.

Is a partially optimized Meta campaign better than optimizing for a higher-funnel event?

Often yes. If you do not have enough purchase conversions, optimizing for a higher-funnel event like add to cart may perform better.

What is the recommended weekly purchase conversion threshold for choosing purchase optimization?

If you are generating more than 10 purchases per week, the recommendation is to optimize for the purchase conversion event.

What should you optimize for if you get fewer than 10 purchases per week?

If you get fewer than 10 purchases per week, look at another conversion event, most likely add to cart.

Why might optimizing for add to cart not produce the same results as optimizing for purchases?

Meta can find people likely to add to cart, but those people are not always the ones most likely to purchase.

Does optimizing for add to cart guarantee purchase intent?

No. People who add to cart are not necessarily as likely to complete a purchase as those found through purchase optimization.
