Remarketing audience duration in Google Ads and Meta: how long a Bangalore business should keep chasing the same visitor

Google Ads lets you keep a visitor in a remarketing list for up to 540 days. Meta caps most website custom audiences at 180 days, though purchase-based audiences can now run to 730 days as of May 2026. Matching that window to how long your actual sales cycle takes, rather than maxing it out because the option exists, is what decides whether remarketing spend converts or just follows someone around after they have already bought elsewhere.

Why the default duration is rarely the right one

Most Bangalore accounts I look at were set up once and never revisited: whatever the platform defaulted to at account creation is still running. Google Ads defaults a new remarketing list to 30 days unless someone changes it. For a restaurant or a salon, where the decision to visit gets made within a day or two, that default is close to right. For a spine clinic where a patient researches for three weeks before booking a consultation, or a home renovation business where the quote-to-booking gap runs a month, 30 days cuts the list off before the visitor has finished deciding, and the ad spend on remarketing simply stops working for the two-thirds of the funnel that mattered most.

What Google Ads actually lets you set

Google's own support documentation on how data segments work confirms the ceiling: 540 days, with the clock resetting each time the visitor returns to the site or app. That reset detail matters more than the headline number. A visitor who checked a service page once eight months ago and never came back drops off the list well before 540 days if the membership duration is set shorter, but a visitor who keeps returning to compare, without converting, stays remarketable for as long as they keep coming back. For a business selling something researched over weeks rather than decided in a session, that reset behaviour is the actual lever, not the maximum number itself.

What Meta changed in May 2026

Meta's default for most website custom audiences is still capped at 180 days. What changed is narrower and easy to miss: starting 18 May 2026, audiences built from purchase events specifically can run to 730 days, with existing 180-day purchase audiences upgraded automatically unless a business opts out. A retail marketing analysis of the change lays out who benefits: categories with a long gap between purchases, home goods, high-ticket apparel, anything bought once every year or two, can now build a lookalike seed audience or an exclusion list from two years of buyers instead of six months. For most Bangalore service businesses, this only applies if purchase or lead events are set up as a distinct event type rather than folded into general website traffic, which is worth checking before assuming the extended window applies.

Matching audience duration to your actual sales cycle

The right number is not the maximum on either platform. It is however long a real customer actually takes, from first visit to converting, plus a margin for the ones who take longer than average. A business that has never measured this is guessing, and the honest fix is to pull the lag between first touch and conversion out of Google Analytics or the CRM before setting a duration at all. Once that number exists, a Google Ads remarketing list runs a little past it, not to 540 days by default, and a Meta custom audience gets the same treatment within its own 180-day or 730-day ceiling depending on the event type. Overshooting the real sales cycle by a lot does not add reach worth paying for; it mostly adds impressions shown to people who already decided one way or the other, which is the same waste as the attribution window mismatches between platforms that quietly inflate a monthly report without inflating actual results.

This is the kind of setting that gets checked once at account setup and never again, which is exactly the gap Studio Happens looks for on every Bangalore performance marketing account it takes on, because getting it right costs nothing beyond the time to change a dropdown, and getting it wrong quietly burns budget every month it goes unnoticed.

Frequently asked questions

What is the maximum remarketing audience duration in Google Ads?

540 days, and the clock resets whenever the visitor interacts with the site or app again. The default for a new list is 30 days, so most accounts are running a much shorter window than the platform allows unless someone has changed it.

How long do Meta custom audiences last?

Standard website custom audiences cap at 180 days. Audiences built specifically from purchase events can run to 730 days as of 18 May 2026, provided purchase is tracked as its own event rather than general site traffic.

Should a Bangalore business set remarketing duration to the maximum on both platforms?

Usually not. The right duration matches your real sales cycle, measured from first visit to conversion, plus a margin. Setting it to the platform maximum by default usually just spends more on people who already converted or already moved on.

Does a longer remarketing window cost more?

Yes, because the audience pool grows and Google or Meta serves more impressions against it. A longer window is only worth the extra spend if your sales cycle genuinely runs that long; otherwise it is budget spent chasing people who are no longer deciding.
