Remarketing

Remarketing is Google's word for showing ads again to people who already visited your website or used your app, the same idea Meta calls retargeting.

You have people landing on your site every day who do not buy, do not fill in the form, and do not call. Most of them leave and you never hear from them again. Remarketing is how you tag those visitors and put your ads back in front of them as they move around the web, watch YouTube, or scroll through their Gmail promotions tab. You can go broad and follow everyone who came to the site, or you can get specific and only chase people who saw a product, started a checkout, or hit your pricing page.

Because you are talking to people who already know your name, the ads usually look cheap and the return on ad spend looks fat. That is the trap. A visitor who was going to buy anyway, who was always going to type your name into Google tomorrow, still gets counted as a remarketing win even though your ad changed nothing. You end up paying to reach someone who was already reaching for their wallet, and the dashboard hands you the credit.

Here is the honest catch. Like all retargeting, remarketing flatters itself, because a big share of those conversions were coming back on their own, and the whole thing leans on tracking that privacy changes and cookie limits keep shrinking every year. Your lists get smaller and blurrier over time, so this can sharpen a campaign but it can never be the whole campaign.

Use it to catch the ready, not to prove the strategy.
