Information about the new “Andromeda” algorithm

The Andromeda algorithm is a new generation of ad delivery in the Meta ecosystem. Below is a structured overview of materials, parameters and target metrics.

General information about the algorithm

The Andromeda algorithm is a new generation of ad delivery in the Meta ecosystem (Facebook, Instagram and others).

Key features:

  • It replaces the old targeting logic (demographics, interests) and focuses on behavioral signals, creative assets and automation.
  • The system now answers not so much “who should see the ad” as “which ad should be shown to which user”.
  • It requires more creative variety and simpler campaign structures: broad audiences and fewer small ad sets.
  • Technically, it is based on deep neural networks, specialized hardware (for example, NVIDIA Grace Hopper Superchip) and hierarchical creative indexing.
  • It is not a magic button: results depend on creative quality, conversion data and the right strategy.

Previously, advertisers focused on audience segments and many settings. Now it is more important to give the algorithm room to work (broad audience + many creatives) and let it optimize delivery. Precise interests and many small ad sets become less effective.

Materials for Andromeda

What materials are needed for effective work

For Andromeda to learn and optimize delivery, it needs a varied set of creatives, correctly configured tracking and a simple campaign structure.

The set of materials determines how flexibly the algorithm can select ads for different audience segments. The broader the audience and the more varied the creatives, the faster Andromeda finds working combinations.

Prepare several ad concepts, headline and copy variants, a landing page with a clear conversion and correct event tracking through Pixel/Conversions API. Simplify campaign structure so the signal is not diluted.

All materials should be aligned with business goals: which actions count as conversions, which audiences matter first and which KPIs are expected at the test stage.

A typical Andromeda launch set includes:

  • 15-30 second video creatives with different messages and formats.
  • Static banners and carousels with visually different concepts.
  • Several headline and body copy variants for different pains/benefits.
  • A landing page or website with a clear target action and UTM tagging.
  • Configured Pixel and Conversions API with events for key conversions.
  • A campaign with broad audience, automatic placements and basic exclusions.
  • A plan to refresh creatives every 7-14 days.

Set

Start

video + carousel
Element Quantity / duration Format / resolution
Main video 1 video 20-30s 16:9 — 1920×1080
Short versions 2 videos: 6s and 15s 16:9 / 9:16 — 1080×1920
Vertical formats 1-2 additional videos 9:16 — 1080×1920
Carousel 5-7 cards 1080x1080 or 1080x1350
Previews / covers 3-5 variants 1280x720 or 1920x1080

Practical example

What a starter set can look like

This set gives Andromeda enough signals: short videos work for reach and hook testing, a longer video explains the offer, a carousel details the product, and covers improve CTR.

In practice, each audience segment should have its own “video + carousel” combination, but even a basic set of 3-4 videos and 5-7 carousel cards already lets the algorithm optimize delivery consistently.

Parameters of these materials

Text description

When preparing materials, define parameters that help Andromeda work optimally: creative variety, broad audience, regular refreshes, correct tracking and a simple campaign structure.

Parameter Recommended value Notes
Number of creatives 8-15+ per ad set Quality variety is what matters
Audience Broad, without many small segments Gives the algorithm more data for learning
Formats Video + images + carousel Allows testing different presentation formats
Creative refresh Every 7-14 days Helps avoid ad fatigue
Conversion tracking Pixel + Conversions API on key events Without signals, performance drops
Campaign structure 1 campaign → 1 ad set (or minimal structure) A simplified structure works better for the algorithm
Campaign budget optimization (CBO) Enabled The algorithm allocates budget itself
Exclusions Exclude existing customers/non-target traffic Cleans the signal and improves learning

Possible performance benchmarks

How to calculate results in Andromeda

After launch, track ROAS, cost per conversion (CPA), CTR, conversion rate (CVR), creative refresh frequency and budget spend. Below are approximate target values for these metrics.

Metric Target value* Comment
ROAS 3–5× $3-5 return per $1 spent
CPA Depends on the niche (for example, $10-50) Depends on average order value and competition
CTR 1.0–3.0 % Working range for social networks
CVR 2.0–5.0 % Conversion from click to target action
Refresh frequency Creatives every 7-14 days Required for stability
Creatives per campaign 8–15+ Minimum for testing hypotheses

*Values are approximate and depend on the niche, market and offer.

Metric calculation with a $5 per day budget

Suppose we launch a campaign with a $5 per day budget and these target metrics: ROAS = 4×, CPA = $20, CTR = 2%, CVR = 3%. Below is an approximate calculation by day, week and month.

Calculation table

Period Budget Expected ROAS Expected revenue Approximate conversions
1 day 5 $ ≈20 $ ~0–1
7 days 35 $ ≈140 $ ≈2
30 days 150 $ ≈600 $ ≈7–8

If ROAS rises to 5×, revenue will be higher, while a higher CPA will reduce the number of conversions. It is important to test creatives regularly, refresh combinations and give the algorithm time to learn.
