Increase Return on Ad Spend by personalizing your website

Most ecommerce teams already personalize their paid ads. Facebook shows different content to new vs. returning users. Search ads speak directly to the query. Display ads are built for a specific interest or audience segment.

Why? Because it works. Ads that are personalized get more clicks, better engagement, and higher relevance scores. Which means, lower cost, better targeting, and higher return. But what happens after the click?

Too often, users click on a personalized ad, and land on a generic website. E.g. a potential customer has searched for a yellow bike. The landing on the bike shop however shows a listing of all bikes. The user has to start his journey all over again.

This isn’t just a missed opportunity for a better experience, it’s bad for business. It lowers conversion rates and reduces your ROAS (return on ad spend). The fix isn’t more ad budget. It’s about adding consistency by matching your website.

Some brands try the SEO-style landing page approach

One workaround we see is bulk-generating pages for every keyword or ad group. This can boost your quality score and satisfy the search algorithm, but it doesn’t always convince the user. These pages are built for Google, not for people.

They often lack relevance, design quality, or proper integration with the rest of your site. And once you have hundreds of them, updating becomes a challenge.

Instead of generating new pages, personalize the existing ones

You already know what campaign, keyword, or ad group brought the visitor in. So use this information. If the ad was about yellow bikes, highlight yellow bikes. If it mentioned free shipping, surface that message again.

For example:

  • On a category page, pre-fill filters to show relevant products first
  • On a homepage, change banners or content blocks based on campaign
  • On a product page, reinforce the offer or message shown in the ad

It’s faster than building a new page. And more importantly, it keeps the message clear and consistent for the user.
