The main traffic acquisition channels
- Organic search (SEO): ranking in the unpaid results for searches your customers make.
- Paid search: ads on Google and Bing for chosen keywords.
- Social media: organic posts and paid social ads.
- Email: newsletters and automated emails to your own list.
- Referral: links from other websites, directories and partners.
- Direct: people who type your address or use a bookmark.
- Display and video: banner and video ads on websites, apps and YouTube.
The Traffic acquisition report
In Google Analytics 4, the Traffic acquisition report shows sessions, engagement and conversions by channel, source and campaign. Use it with UTM-tagged links to see which channels bring customers, not just visits.
Building a traffic mix
Relying on one channel is risky: an algorithm update or a price rise can cut traffic overnight. Combine long-term channels such as SEO, content and email with faster channels such as paid ads, and measure the cost and value of each.
Traffic acquisition example
A language school checks its Traffic acquisition report. Organic search brings 55% of sessions and 40% of the enquiries. Paid search brings 15% of sessions and 35% of enquiries. Social brings 20% of sessions and almost no enquiries. The school keeps investing in content and search ads, and uses social mainly for brand and for free trial offers.

- Add columns for conversions and revenue, not only sessions.
- Compare cost per conversion for paid channels.
- Look at trends over several months.
- Decide where to invest more, test or stop.
- Make sure all campaign links use UTM tags so that channels are labelled correctly.
Traffic acquisition mistakes
