A few years ago, CTR was the main star of performance analytics. The click-through rate decided everything: whether the link was good or not, whether to scale or to the trash. But in 2025, it doesn’t work anymore. Because ads that collect clicks but don’t hold attention will no longer win the auction.

TikTok, Meta, YouTube – all major platforms have started counting not only clicks, but also how long your ad actually lives in the user’s head. The algorithm sees whether the user lingered or just “clicked past.” And if you don’t stay, you are eaten by the one who knows how to keep you.

What are attention metrics, why are they replacing classic CTR/CPC, how has the approach to performance marketing changed, and what is really important to measure now. Without water, with diagrams, examples, and a clear answer to the main question: what to count now, so as not to waste it.

What are time-spent metrics and why is CTR no longer enough?

Once upon a time, it was enough for a user to click. CTR OF 5%? Yay, the link is flying. But in 2025, this is no longer a performance metric – it’s just the first, often false step.

Time-spent metrics are:

  • Time on screen – how long the ad was in the user’s visual area (Meta, TikTok, YouTube count it in milliseconds)
  • Watch time – how many videos were actually watched (TikTok: the first second is important, YouTube Shorts: average watch-through rate)
  • Scroll depth – how deep the user scrolled the page (relevant for landing pages, blogs, native advertising)

These indicators do not answer the question “did they click?”, but “did they stay and read/watch?”. And this has become critical for algorithms.

Why does CTR cheat?

Imagine a banner: “This service gives out $300 every day. Click – and see for yourself!”

There will be a lot of clicks. But after the click:

  • 90% of users immediately close the landing page
  • Time on page: 3-5 seconds
  • Scroll depth: 15%
  • Zero conversions

CTR is high, CPC is acceptable, but contact quality is zero. The algorithm sees this and cuts the impressions because the ad does not “catch”, although it collects clicks.

Why is view time more important than clicks?

Time = attention.And in the era of attention economy, attention is the main currency.

A promotional video that keeps the user engaged for at least 6-10 seconds has a higher chance of being successful

  • get into the audience expansion algorithm
  • get a cheaper CPM
  • show up to more relevant people

Compare:

  • Creo #1: CTR 1.5%, average view – 2 seconds
  • Creo #2: CTR 0.9%, average view – 9 seconds

Meta and TikTok will take the second option. Because the first is just a click, and the second is attention that leads to action.

CTR is no longer the main character. If your ad doesn’t hold the eye, it loses even with a high CTR. That’s why we look not only at how many people clicked, but how long they watched. And this is where the right analytics starts.

Meta, TikTok, YouTube: how platforms change priorities

Advertising algorithms no longer look at clicks. They measure attention. And each platform has its own triggers that really affect how much you pay and whether you will be shown at all.

Meta Ads: more time – lower price

  • Engagement Time per View – how long the user actively interacts with the creative (looks, does not swipe, reads the text).
  • Hold Rate – what percentage of users stayed the first 3 seconds (this is the critical zone).

What does this mean? If the creative is “held” for at least 3-5 seconds, it gets a higher Relevance Score and better delivery conditions. Even if the CTR is not top.

Example: Two videos have the same CTR of 1.2%, but one is played for 6 seconds, the other for 1.5 seconds. The first one gets twice as many impressions.

TikTok Ads: the one that stays for 2 seconds is already a hero

  • Early Hook Retention – the critical first 1-3 seconds that decide whether the video is picked up by the algorithm.
  • Average Watch Time – how long your video is watched on average. The algorithm promotes creos that are watchedto the endor at least 50-80%.

What does this mean?

Weak hook = minus 90% of coverage. TikTok wants the user to “stick” and view the maximum – then you will be pushed further.

Example: Even if CTR = 0.7%, but watch time = 10+ seconds – creo lives long. TikTok gives it “life after death” even on a zero account.

YouTube Ads: a classic that is also changing

  • View-through rate (VTR) – how many people watched at least 30 seconds or to the end (if the video is short).
  • Average View Duration – the average viewing time, which is critical for Shorts and In-stream.

What does it mean?

YouTube ranks better those videos that don’t just start, but leave the viewer inside. Advertising that is “skipped” at the 5th second is ineffective.

Example: A video with a VTR of 50% gets a lower CPA than a video with a 70% CTR, but with a VTR of 10%. Because there is no point in clicking if the viewer has not listened to the message.

It doesn’t matter how many times you were clicked on if the user went to get coffee afterwards. The platforms measure your quality by dwell time, not by shouting “Click now!”. And if you’re in arbitrage or media, you need to know these new metrics better than CTR.

Scroll depth, retention, and “view after the fact”: how to measure attention

In 2025, we no longer ask “did they click?”. We ask “did they actually watch?”. Because attention is not a number in statistics, but behavior: whether the user stayed on the page, read it, listened to it, or reached the CTA.

Scroll depth: a new “dimension of trust”

In textual content, classic metrics (such as Time on Page) no longer give an accurate signal. Because someone could just open a tab and go make tea.

Instead, scroll depth. It shows how deep the user scrolled the page.

  • Have you reached 75%? It means that the content really engaged you.
  • Stuck at 25%? Maybe it’s a weak headline or a boring introduction.

This is the same “attention map” that is now used not only by SEOs, but also by arbitrageurs working with longreads, landing pages, and neutrals.

Video retention: critical seconds

On Meta, TikTok, and YouTube, it is important not only to show the video but to keep it for at least a few seconds. Because:

  • In Meta 3 seconds of holding = conditional “interest”
  • On TikTok the first 2-3 seconds = either your chance for reach or a swipe into oblivion
  • In YouTube Shorts watch time affects delivery more than clicks

Why are 3 seconds more important than a click?

CTR can be high if you have a clickbait or a big “click” button. But if the viewer immediately returned back, the platform sees it.

On TikTok, for example, a video with 10+ seconds of viewing gets organic even if the CTR was average.

And in Meta Engagement Time per View directly affects CPM – longer hold = lower cost per impression.

That’s why today’s “true view” is not a click, but how long people actually held their attention. And if your ad only shouted, but did not hold, it simply will not be shown again.

How to adapt analytics to new metrics?

Old dashboards are no longer working. If you are still measuring the success of your creo only by CTR, it is time to upgrade your analytics. Because modern arbitration is not about “clicked?” but about “sat through?”, “listened?”, “completed?”. And these metrics can really be connected.

How to add scroll depth in Google Tag Manager?

Scroll Depth is your first answer to the question “did you read it at all?”. It takes 5-10 minutes to set up via GTM.

How to do it:

  1. In GTM, create a new Trigger → Scroll Depth
  2. Set the levels: 25%, 50%, 75%, 90% – depending on the length of the page
  3. Create Tag → GA4 Event, specifying the type parameters scroll_depth = 75
  4. Connect to Google Analytics or BigQuery and see where users merge

Tip: track depth on prelends, natives, and blog separately – there is the most attention loss.

How to track average view time through TikTok Pixel or Events API?

TikTok already has an Events API that can be customized for your own analytical purposes:

What to track?

  • Video Watched (seconds, % viewed)
  • Engaged View (if the user interacted with the video)
  • Complete View – 100% view (rare, but top)

How it is implemented:

  • Through TikTok Events API → site or server side settings
  • Through TikTok Pixel + GTM → event tracks like ViewContent with timers

The updated 2025 dashboard is not just “CTR + budget”. This is an X-ray of user attention, which shows not only whetherthey clicked, but what happened after. And it is these numbers that help to distinguish between the creo that really works and the one that just “flashes” in the feed.

Here’s what you should have in your report if you want to really evaluate your effectiveness:</span

  • CTR – long live the CTR, but without fanaticism. This is a guideline, not a sentence. Look at it in conjunction with in-depth metrics.
  • Average Time on Screen – how long the user actually saw your banner or video. If it’s 0.4 seconds, no “impression” is left.
  • Scroll Depth (via GA4 or GTM) – whether the user reached the CTA or abandoned the second paragraph. Ideal for landing pages and blogs.
  • Average Watch Time (TikTok, Meta) is the main metric for videos. The longer the video is watched, the cheaper the cost per impression.
  • Hook Retention – how many % of users fell off in the first 3 seconds. If it’s 80%, you need to redo the creative, not stretch your budget.
  • View-through Conversions – the user did not click, but returned and converted. Without this metric, you don’t see half of the real ROI.
  • Bounce Rate – silence after a click is also a signal. If the user leaves instantly, the problem is not in traffic, but in the copy or landing page.

Tip from arbitrager to arbitrager: Collect these indicators in Google Looker Studio or Data Studio. One glance and you can see which creo is really alive, and which one just pumps up the CTR but kills the profit.

Because today advertising is not about clicks. It’s about retained attention. And it can already be counted

Practice: how to evaluate creo through attention metrics?

TikTok and Meta no longer just look at clicks. If a user doesn’t watch even 3 seconds or immediately opens the video, the algorithm considers it “not interesting”. And it starts to strangle the creo.

Creo A is short, with a bright hook, subtitles, and a clear CTA.
Creo B – long intro, slow pace, soft message. As a result, A is shown more often, cheaper, and retains ROI. And B gets into the “gray list” due to low engagement, although the CTR is fine.

When CPC is low and view time is dead

It can be like this:

  • CPC is ridiculous,
  • CPM is perfect
  • And sales – zero.

This is the case when the creo seems to attract attention, but does not hold it. The user clicked… and forgot. So the headline won, but the content lost.

Tip: In such situations, don’t change the audience or bid immediately. Look at the time spent. Because sometimes you don’t need a new creo, you need a new one in the first 3 seconds.

Attention metrics are not about “beauty will save the world,” but about “leave the user for a couple more seconds.” They show whether your video has really hooked them or just promised to hook them. And the sooner you start tracking them, the less you’ll waste.

Attention is the new currency

CTR no longer cuts the truth in the heart. In 2025, it’s more likely to embellish a report than actually explain what happened to creo.

Now, conversions are not won by the first to click, but by the one who holds the attention: makes you watch, read, listen. Platforms see this and give out reach, optimization, and cheaper CPM to such connections.

If you are still evaluating creo only by CPC or CTR, then you are not seeing half the picture. And this half is the one where the budget is drained or the profit soars.

A final tip: Add at least one attention metric to your analytics – average view time, scroll depth, engagement time. These are simple changes that can change everything.
