Step 2: Add URL parameters to your ads

Ad platforms do not tell your website which ad was clicked. These parameters do. Wexlyn reads them on the landing page and creates a source for every ad automatically, named after the ad, grouped by ad set or ad group.

Copy the string for each platform below. Tracking → Sources → Auto-source parameters has the same list with copy buttons.

Google Ads

Account level → Settings → Tracking → Tracking template:

{lpurl}?gc_id={campaignid}&h_ga_id={adgroupid}&h_ad_id={creative}&h_keyword_id={targetid}&h_keyword={keyword}&h_placement={placement}

Performance Max and Smart campaigns cannot pass ad ids. Use their campaign-level tracking template:

{lpurl}?g_special_campaign=true&gc_id={campaignid}

Click Test in Google Ads after saving.

Meta (Facebook and Instagram)

Ad level → URL parameters field (not the website URL):

fbc_id={{adset.id}}&h_ad_id={{ad.id}}

Tip: in Ads Manager select all ads, Edit, open URL parameters, paste once, apply to all. Save a column preset that shows the URL parameters column so you can spot ads missing it.

TikTok

Ad level → Destination URL, append:

?ttc_id=__CAMPAIGN_ID__&h_ad_id=__CID__

LinkedIn

Ad level → Destination URL, append:

?lnk_id={{CAMPAIGN_ID}}&h_ad_id={{CREATIVE_ID}}

Microsoft (Bing) Ads

Account level → Tracking template:

{lpurl}?h_campaign_id={CampaignId}&bng_id={AdGroupId}&h_ad_id={adid}

Performance Max: add &bng_special_campaign=true.

X (Twitter)

X has no dynamic parameters. Append the ad group id by hand:

?twt_id=YOUR_AD_GROUP_ID

Snapchat, Pinterest, Reddit, AppLovin

Each uses its own dynamic tokens; the Auto-source parameters modal in Tracking → Sources lists the current string for each.

Manual sources and emails

For anything that is not an ad (an email, a YouTube description, a partner link) use:

?el=Email-Name            organic email or link source
?sl=Source-Name           any manual source
?he={{contact.email}}     passes the reader's email so the visit is matched to the lead

Add &htrafficsource=youtube or &hcategory=Newsletter to control the traffic source icon and category.

Check your work

Open an ad from the platform's preview and look at the landing page URL: every parameter above should be visible. Then check Tracking → Sources: a new source appears within a few minutes, named after the ad.
