# Long-term on-site personalisation ### 1. The problem: website amnesia (ITP) Due to browser restrictions (ITP on Safari, for example), traditional identifiers stored in the browser are often deleted after only 24 hours or 7 days of inactivity. * **Consequence**: A visitor who returns after 10 days is treated as a complete stranger. All personalisation data (last products viewed, category preferences, specific banners) is lost. ### 2. The solution: Long-term memory (13 months) Integrating First-ID into your Commanders Act platform allows you to restore visitor recognition: * **Persistent recognition:** First-ID assigns a unique identifier that remains stable for up to 13 months, bypassing browser cookie purges. * **Enriched profiles**: The Commanders Act CDP uses this stable ID to link each new visit to the same historical profile. * **Frictionless experience**: The site ‘remembers’ the user, allowing it to display relevant content from the very first second of their visit, even after several months of absence. ### 3. Key benefits * **Improved UX**: Offer a smooth browsing experience by immediately displaying the visitor's favourite categories or products. * **Increased conversion rate**: By shortening the path to purchase through relevant personalisation, you make decision-making easier. * **Increased engagement**: The relevance of messages (pop-ins, home page banners) reinforces the feeling of recognition and attachment to the brand. ### 4. How it works 1. **Identification**: First-ID recognises the visitor as soon as they arrive on the site, without the need to log in. 2. **Retrieval**: Commanders Act instantly calls up the historical profile associated with this ID in the CDP. 3. **Personalisation**: The TMS triggers the display of a specific banner or a selection of products based on visits made several weeks ago. 4. **Satisfaction**: The user enjoys an experience tailored to their real needs. ### Need help with implementation?
