LähiTapiola’s use of first-party data results in an increase in conversions

LähiTapiola, a major insurance provider based in Finland, wanted to expand its digital acquisition strategy while also maintaining budget efficiency. Partnering with Google and an agency, OIKIO, they implemented the Google tag across LähiTapiola’s entire website. Now able to use first-party data with its Google Ads campaigns, the company has gained a 37% increase in conversions and a 7% decrease in cost per conversion.

How sitewide tagging works

Sitewide tags, such as the Google tag, place first-party cookies on your website.
Customers interact with your ad and the sitewide tag stores first-party cookies with info about the interaction.
When the customer converts on your website, the tag reads this cookie and records the conversion in your Google Ads account.

Frequently asked questions

What data does the Google tag collect?

Google Ads only collects data on pages where you have deployed the associated tags. It’s important to provide users with clear, comprehensive information about the data you collect on your website, and to get consent where legally required or required by Google’s policies.

What is the difference between the global site tag and the Google tag?

To help you keep pace with industry changes and continue measuring performance, Google has further improved the tagging experience. The Google tag is a single, reusable tag that replaces the global site tag and simplifies measurement with new capabilities that don’t require additional code. If you have the global site tag set up already, you will not need to make any changes. Your existing tag implementations will continue to work and will be automatically updated to the Google tag.

Why would I want to set up sitewide tagging using Google Tag Manager instead of Google Ads?

If you need to manage multiple tags on your website, we recommend using our comprehensive enterprise tag management system, Google Tag Manager. It allows you to configure and deploy tags from a variety of Google and non-Google products within the same interface. If you’re looking for simpler implementation directly on your site, we recommend setting up sitewide tagging via the Google tag to power measurement across Google Ads and Google Analytics.
