Soku AIPaste the landing page
Use the exact URL the ad will point to, including any query string or #section it already has. The builder adds parameters before the # and replaces, rather than repeats, any utm_ key the page already carries.

Free UTM Builder with Ad Platform Macros
Build tagged campaign URLs that keep your existing query string and #anchor, encode properly, and stay lowercase. Presets drop in each ad platform's own dynamic macros — Meta, Google Ads, TikTok, LinkedIn, Microsoft Advertising and ChatGPT Ads — and nothing you type leaves your browser.
GA4 parameters6 platform presets
Existing query parameters and #anchors are kept.
Where the click came from
The channel type
The campaign
Keyword or audience
The creative or link
UTM values are case-sensitive, so “Facebook” and “facebook” become two sources in your reports. Both rules apply to text you type only. Macros such as {{campaign.name}} are left untouched: they are filled in by the platform at click time with whatever the campaign is called there.
Tagged URL
https://example.com/shoes?color=red&utm_source=newsletter&utm_medium=email&utm_campaign=spring_sale#reviews
Parameters only
utm_source=newsletter&utm_medium=email&utm_campaign=spring_sale
For URL-parameter fields such as Meta’s URL parameters or a Google Ads final URL suffix.
Checks
- Kept #reviews at the end. Parameters have to sit before the #, because nothing after it is sent to the server.
- Macros from six platforms' own docs
- Existing query and #anchor kept
- Lowercase and space rules, macro-safe
- Bulk mode: one URL per ad name
Three deliberate steps
Fill the tags or load a platform preset
Type source, medium and campaign yourself, or pick Meta, Google Ads, TikTok, LinkedIn, Microsoft Advertising or ChatGPT Ads to fill the fields with that platform's own macros, so the campaign, ad set and ad values are written at click time.
Fix the warnings, then copy
Clear anything flagged — a missing utm_medium, mixed case, a gclid copied from a real click — and copy either the full URL or the parameters-only line for the platform's URL-parameters field.
Where the macros come from
Every platform’s dynamic parameters, side by side
Each list was read from the platform’s own help page on October 12, 2026, not copied from another builder. Note the four syntaxes: Meta and LinkedIn use double braces, Google, Microsoft and ChatGPT Ads use single braces, and TikTok uses double underscores. A macro from one platform reaches your analytics as literal text on any other. The UTM fields themselves follow Google’s GA4 URL builder guidance.
| Platform | Documented macros | Where they go | Source |
|---|---|---|---|
| Meta (Facebook & Instagram) | {{campaign.id}} {{adset.id}} {{ad.id}} {{campaign.name}} {{adset.name}} {{ad.name}} {{placement}} {{site_source_name}} {{media_type}} | Ads Manager → ad level → Tracking → URL parameters. Paste the “parameters only” line, not the full URL. | Meta Business Help: dynamic URL parameters |
| Google Ads | {campaignid} {adgroupid} {creative} {keyword} {matchtype} {device} {network} {targetid} {placement} {loc_physical_ms} {assetgroupid} | Campaign or account settings → Campaign URL options → Final URL suffix. Paste the “parameters only” line. | Google Ads Help: ValueTrack parameters |
| TikTok Ads | __CAMPAIGN_NAME__ __CAMPAIGN_ID__ __AID_NAME__ __AID__ __CID_NAME__ __CID__ __ADID_V2_NAME__ __ADID_V2__ __PLACEMENT__ | Ad level → Destination → URL parameters (or the website URL itself). TikTok can also add utm_source and utm_medium for you. | TikTok Ads Manager Help: About UTM parameters |
| LinkedIn Ads | {{ACCOUNT_ID}} {{ACCOUNT_NAME}} {{CAMPAIGN_ID}} {{CAMPAIGN_NAME}} {{AD_SET_ID}} {{AD_SET_NAME}} {{AD_ID}} {{AD_NAME}} | Campaign Manager → account or campaign level → URL parameters. Dynamic parameters can only be set there, not per ad. | LinkedIn Help: URL tracking parameters in Campaign Manager |
| Microsoft Advertising | {Campaign} {CampaignId} {AdGroup} {AdGroupId} {AdId} {keyword:default} {MatchType} {BidMatchType} {Device} {Network} {TargetId} {msclkid} | Account, campaign or ad group → URL options → Final URL suffix. Paste the “parameters only” line. | Microsoft Advertising Help: tracking and URL parameters |
| ChatGPT Ads | {campaign_id} {ad_group_id} {ad_id} {ad_account_id} | Ads Manager → ⋯ → Edit campaign (or ad group, or ad) → Landing page query parameters. | OpenAI Help: Measure Results (ChatGPT Ads) |

Why Soku
Tags are the input. The report is the point.
A clean UTM scheme is what lets you compare channels on the same terms. Soku is built for the part after the link goes live.
Performance by UTM, across channels
Soku reads the UTM tags on your synced campaigns and can break spend and results down by utm_source, utm_medium, utm_campaign and utm_content — so a consistent scheme pays off in one view rather than four exports.
Campaigns run from one chat
Soku runs campaigns across Meta, Google, TikTok and ChatGPT Ads, and changes go live only after you approve them.
New creatives to put in utm_content
Soku Creatives generates image and video ads from a product URL or a few photos, and Soku A/B-tests them on live traffic — which is exactly what utm_content is there to tell apart.
Use cases
Who reaches for this, and when
Performance marketers
One scheme across every paid channel
Load each platform's preset in turn and keep source and medium identical in spirit — paid_social for social, cpc for search — so GA4 and your warehouse group the traffic the same way no matter where it was bought.
Agencies and freelancers
Hand clients a link that cannot drift
Name macros mean nobody has to retype a campaign name into a URL. Bulk mode turns a list of ad names into one tagged link each when a platform has no macro for what you need, such as offline or influencer placements.
Email, partner and organic teams
Tag the links that ad platforms do not
Newsletters, creator bios, QR codes and partner placements have no auto-tagging. Use the same lowercase and underscore rules as paid so the sources line up in one report instead of splitting into Email, email and e-mail.
Questions before you run it
- What is a UTM builder?
- A UTM builder adds tracking parameters — utm_source, utm_medium, utm_campaign and optionally utm_term and utm_content — to a landing page URL, so analytics tools can tell which campaign sent each visit. Google's GA4 documentation says to always include utm_source, utm_medium and utm_campaign, and also accepts utm_id, utm_source_platform, utm_creative_format and utm_marketing_tactic, though it notes the last two are not currently reported in GA4 properties. This builder is free, needs no account, and runs entirely in your browser.
- What are the dynamic UTM parameters for Facebook and Instagram ads?
- Meta documents {{campaign.id}}, {{adset.id}}, {{ad.id}}, {{campaign.name}}, {{adset.name}}, {{ad.name}}, {{placement}} and {{site_source_name}}, plus {{media_type}} for Advantage+ catalog ads. {{site_source_name}} returns fb, ig, an, msg or th. The name macros use the name each item had when it was first published, so renaming a campaign later does not change the value. Paste them in the URL parameters field at ad level.

- Do I need UTM tags on Google Ads if auto-tagging is on?
- For Google Analytics, mostly not. Auto-tagging adds a gclid to every click, is on by default for new accounts, and Google's help page states that GA4 prioritises auto-tagging over manual tagging. Manual UTMs still help other analytics tools, CRMs and warehouses that cannot read gclid. Google Ads has no campaign-name ValueTrack macro, so use {campaignid}, {adgroupid}, {creative} and {keyword} for IDs and the keyword, and type the campaign name yourself — ideally in the Final URL suffix.
- Should UTM parameters be lowercase?
- Yes. Google's GA4 documentation states that parameter values are case-sensitive — utm_source=google and utm_source=Google are different sources — and recommends lowercase as standard practice. The builder lowercases and replaces spaces in the text you type, but never alters a macro: what a macro inserts is whatever the campaign is called in the ad platform, so lowercase names there too.
- Which TikTok, LinkedIn and ChatGPT Ads macros can I use?
- TikTok lists __CAMPAIGN_NAME__, __CAMPAIGN_ID__, __AID_NAME__ and __AID__ (ad group), __CID_NAME__ and __CID__ (creative), __PLACEMENT__, and __ADID_V2_NAME__ / __ADID_V2__ for upgraded Smart+ campaigns. LinkedIn lists {{ACCOUNT_ID}}, {{ACCOUNT_NAME}}, {{CAMPAIGN_ID}}, {{CAMPAIGN_NAME}}, {{AD_SET_ID}}, {{AD_SET_NAME}}, {{AD_ID}} and {{AD_NAME}}, set at account or campaign level only. OpenAI documents {campaign_id}, {ad_group_id}, {ad_id} and {ad_account_id} for ChatGPT Ads, all IDs. Each list was checked against the platform's own help page on October 12, 2026.
