If you're running paid ads on Google, LinkedIn, Facebook, or other platforms, connect them to HubSpot so you can see which ads actually generate customers, not just clicks.
Connect Google Ads
Go to Settings → Marketing → Ads.
Click "Connect account" and choose Google Ads from the list.
You'll be redirected to Google to authorize the connection. Make sure you're logged into the Google account that manages your ads.
Once connected, HubSpot will start pulling data from your Google Ads campaigns: impressions, clicks, cost, and most importantly, which ads generated leads and customers.
This connection lets you see the full funnel: someone clicks your ad, lands on your website, fills out a form, becomes a lead, and eventually becomes a customer. Without this connection, you only see clicks and cost. With it, you see ROI.
Connect LinkedIn Ads
The process is similar for LinkedIn Ads.
Go to Settings → Marketing → Ads, click "Connect account," and choose LinkedIn Ads.
You'll be redirected to LinkedIn to authorize the connection. Make sure you're logged into the LinkedIn account that has access to your Campaign Manager.
Once connected, HubSpot will pull in campaign data and match LinkedIn ad clicks to contact records. You'll be able to see which LinkedIn campaigns generate leads and which are burning budget.
Connect Facebook and Instagram Ads
Facebook and Instagram ads are managed through the same platform (Meta Business Suite), so you connect once and get both.
Go to Settings → Marketing → Ads, click "Connect account," and choose Facebook Ads.
Authorize the connection through Facebook, and HubSpot will start pulling in campaign data, ad performance, and conversion tracking.
If you're running lead gen ads on Facebook (where people fill out forms directly in Facebook without leaving the platform), this connection automatically syncs those leads into HubSpot as contacts. No manual CSV exports required.
Review ad performance in HubSpot
Once your ad accounts are connected, go to Marketing → Ads to see all campaigns in one place.
You'll see metrics like:
- Impressions and clicks (traffic metrics)
- Contacts created (lead generation)
- Deals created (pipeline generation)
- Customers generated (revenue)
- Cost per contact, cost per deal, cost per customer (efficiency metrics)
This is where ROI becomes clear. You might be spending £500/month on LinkedIn ads and £2,000/month on Google Ads, but if LinkedIn generates 50 contacts and 5 customers while Google generates 200 contacts and 2 customers, you know LinkedIn has better ROI even though it costs less.
Without connecting your ad platforms, you're just guessing. With them connected, you have data.
