Look-alike

look-alike audience · look-alike audience · similar audience

Look-alike is an algorithmically found audience similar to your existing clients. The strongest tool in VK Ads, Ya.Direct.

Look-alike is a similar audience found by the advertising platform algorithm based on the profile of your existing clients. The algorithm analyzes behavioral, demographic and psychographic characteristics and finds “similar” ones in the general database of the platform.

The source for look-alike is usually: - List of clients from CRM (emails, phone numbers) - Pixel events (Pixel.Purchase, Pixel.Lead) - Subscribers of the TG channel or VK community - Site visitors for the last 30/90 days

The size of look-alikes is usually 1–10% of the total platform base. In VK Ads I use 1% - the most “dense” audience, more expensive, but of better quality. For scaling - 3–5%.

Look-alike not magic. It depends on the quality of the original list. If your clients list contains 50% random people (for example, they downloaded free material but did not buy), look-alike will be “dirty”. I always clear the source: only paying customers + active in the product for 30+ days.

In my projects, look-alike gives a CPL that is 30–50% lower than “cold” targeting based on interests. This is the most powerful tool in Russian performance after the departure of Google.

Frequently asked questions about Look-alike

What is look-alike (LAL)?+
Look-alike is an algorithm of advertising platforms that finds people similar to a given audience in behavior and interests. You upload a list of buyers or visitors - the platform selects similar ones in its database.
Which audience should we build look-alike on?+
The best results are on customers (not all visitors). The higher quality the source segment, the more accurate the LAL. Descending ROI: buyers → leads → pricing page visitors → all site visitors.
What is similarity 1%, 2%, 5%?+
Percentage of “similarity” of the audience. LAL 1% = most similar to the original segment, but small audience. LAL 10% = wider but less accurate. Start: 1-2%, as it burns out - expand to 5%.
How many “sources” do you need in LAL?+
Minimum 500-1,000 for a stable result. Up to 500, the platform cannot build a reliable similarity profile. For top segments (LAL 1%) 2,000+ is better.
