The five platforms are more useful together than separately. The integrations are not automatic, but setting them up is a one-time task. Here are the four that matter most.
Platform connection map
GA4 sits at the centre. Search Console, Google Ads, and Merchant Center link directly. Meta connects via UTM parameters.
Search Console linked to GA4
When Search Console is linked to GA4, you can see organic search queries inside GA4. Without the link, GA4 shows you that organic search sent 400 sessions this week but tells you nothing about which keywords drove them. With the link, you can see search queries, impressions, clicks, and average position inside GA4's reports. Setting it up takes about two minutes inside GA4's Admin panel.
Google Ads linked to GA4
This is the most important integration. When Google Ads is linked to GA4, clicks from your ads appear in GA4 with full campaign, ad group, and keyword detail. More importantly, you can import GA4 conversion events back into Google Ads, which means Google's bidding algorithms can optimise for real business outcomes (purchases, form fills) rather than just ad clicks. Without this link, Google Ads only knows someone clicked. With it, Google Ads knows someone clicked and then bought something.
Merchant Center linked to Google Ads
If you run Shopping ads (the product listings that appear with images and prices in Google search), Merchant Center needs to be linked to Google Ads. This is what allows Google Ads to pull your products from the feed and show them in Shopping campaigns. Without the link, you can run text search ads but not Shopping ads.
Meta Ads connected via UTM parameters
Meta does not have a direct link with GA4 the way Google's own platforms do. Instead, the connection works through UTM parameters: tracking codes you add to the destination URLs in your Meta ads. When someone clicks a Meta ad with UTM parameters, GA4 records the source, medium, and campaign from those parameters. This means you can see Meta ad traffic in GA4 (alongside your organic and Google Ads traffic) without a direct platform link.
You do not need all four integrations on day one. Start with GA4 and link Search Console (free, immediate value). Add the Google Ads link when you start running paid search. UTM parameters for Meta are worth setting up any time you run a Meta campaign.
