Which visibility channels are best, and how do you track each campaign?

A comparison of online and offline visibility channels by type of business, each with the method for tracking it through to conversion in GA4 and the CRM

The essentials

  • The ranking depends on the business: Google and local for proximity services, SEO and LinkedIn for B2B, Meta, TikTok and Shopping for B2C, AI engines for everyone since 2025.
  • Tracking: each channel is tracked with UTMs, GA4 conversions and, offline, codes, phone numbers or dedicated pages; without tracking, a channel cannot be compared.
  • 2026 benchmarks: Google remains the leading source of visitors (40 to 60% of small business traffic), generative AI accounts for 3 to 10% of discovery and is growing, organic social 5 to 15%.
  • The method: choose 3 to 5 channels, track them all, compare on cost per result over a quarter.

Knowing whether the money spent on being visible is well invested means two things: choosing the channels that match your business, and tracking the visitors and conversions each one brings. This article compares online and offline visibility channels in 2026, then describes for each the method for tracking through to conversion. The choice of platforms by business model is explored in which platforms to favour by business, and measuring the effect of an action in measuring the impact of a communication campaign.

Choosing your channels by type of business

  • Proximity service (tradesperson, healthcare, restaurant): Google Business Profile, local SEO, local Google Ads, reviews; social media in support. The guide is in Google Business Profile.
  • B2B (consulting, industry, software): SEO and content, AI engines, LinkedIn (organic then paid), email, trade shows and webinars.
  • E-commerce: Google Shopping and Performance Max, product SEO, Meta and TikTok, marketplaces, retention email.
  • Consumer brand: video (YouTube, TikTok, Reels), social advertising, influencers, press, then Google to capture the demand created.
  • Everyone: visibility in AI engines, which answer a growing share of questions before any Google search; see visibility in generative AI.

Tracking online campaigns

Online advertising is the simplest part: GA4 automatically recognises organic traffic, Google Ads linked to the account, social media referrals and email with parameters. Three rules make the tracking complete. The first is the UTM convention: every campaign link (social ad, email, partner, QR code) carries a consistent source, medium and campaign name; the method is in tagging your digital campaigns. The second is the conversion: the form, the call, the purchase or the quote request are GA4 key events, imported into the advertising platforms and, in B2B, reconciled with the CRM. The third is reading from a neutral source: each platform claims its own conversions, only GA4 or the CRM allocates them.

Tracking offline campaigns

  1. The dedicated URL: a short, memorable address (mysite.com/radio) that redirects to the target page with UTMs; every visit to that URL comes from the campaign.
  2. The QR code: same principle, with a tagged link; suited to flyers, posters, trade shows and packaging.
  3. The dedicated phone number: one number per medium (press, outdoor, directory) with call tracking; the calls are then imported as conversions.
  4. The promotional code: one code per campaign, read in the e-commerce platform or the CRM.
  5. The question on first contact: “how did you hear about us?” in the form or on the phone, recorded in the CRM; imperfect but useful for channels with no link.
  6. Brand searches: in Search Console and Google Trends, a rise in searches for the company name during and after an awareness campaign measures its indirect effect.
  7. The geographic test: a campaign run in one area and not in another, compared on visits and conversions by city in GA4.

Comparing channels with each other

Once each channel is tracked, the comparison is made on cost per result over a quarter: the full cost of the channel (media, provider, internal time) divided by the conversions attributed by GA4 or the CRM, taking into account the timescale specific to each channel. Awareness channels (video, offline, organic social) are also judged on assisted conversions and brand searches, not on last click. The method for arbitrating budget between channels is in steering your marketing budget with KPIs.

Our advice: before launching a campaign, whatever the channel, write on one line how you will know what it brought in: the tagged link, the conversion measured, the neutral source it is read in, the review date. A campaign that cannot fill in that line should not be launched; it is the simplest way to eliminate the 20 to 30% of visibility spend that is never assessed.

Frequently asked questions

Which is the best visibility channel in 2026?

Google remains the leading source of visitors (30 to 50% of a small business's traffic), followed by advertising, AI engines rising fast and social media. The ranking depends on the business: local for proximity services, SEO and LinkedIn for B2B, Shopping and Meta for e-commerce.

How do you track an online advertising campaign?

With consistent UTMs on every link (source, medium, campaign), conversions configured in GA4 and imported into the platforms, and results read in a neutral source (GA4 or CRM) rather than in each platform, which counts its conversions more broadly.

How do you measure an offline campaign (radio, outdoor, flyers)?

With a dedicated URL or a tagged QR code, a specific phone number, a promotional code, the question “how did you hear about us” in the CRM, the rise in brand searches in Search Console and, for large budgets, a geographic test comparing two areas.

Do you need to be present on every channel?

No: three to five well-tracked channels bring in more than ten poorly run ones. Choose by type of business, track each one through to conversion, compare on cost per result over a quarter and reallocate. A channel that cannot be measured cannot be compared.

How do you see traffic coming from ChatGPT or Perplexity in GA4?

By filtering the session source dimension on chatgpt.com, perplexity.ai, copilot.microsoft.com and the other assistants, or by creating a custom “AI” channel group. Google's AI overviews are counted in organic traffic and cannot be told apart in GA4.
