Het betekent niet automatisch dat de campagne beter presteert. OpenAI beschrijft in het wijzigingsoverzicht van 30 september 2026 nieuwe attributie-instellingen voor GET Insights. Bestaande koppelingen die instellingen weglieten, verdienen daarom eerst een definitiecontrole. <sup><a href=\"#ref-nl-1\" aria-label=\"Bron 1\">[1]<\/a><\/sup><\/p><section aria-labelledby=\"section-nl-1\"><h2 id=\"section-nl-1\">Stel de vensters expliciet in<\/h2><p>De gedocumenteerde standaard is nu dertig dagen na een klik en \u00e9\u00e9n dag na een weergave, met de advertentie-interactie als datumbasis. Voor klikken zijn zeven, veertien of dertig dagen beschikbaar. Het weergavevenster is \u00e9\u00e9n dag of nul; nul sluit weergaveattributie uit. De standaardwaarden gelden onafhankelijk van elkaar. <sup><a href=\"#ref-nl-2\" aria-label=\"Bron 2\">[2]<\/a><\/sup> Een korter klikvenster maakt een rapport dus niet vanzelf uitsluitend klikgebaseerd.<\/p><\/section><section aria-labelledby=\"section-nl-2\"><h2 id=\"section-nl-2\">Onderscheid rapportage van klantgedrag<\/h2><p>Neem een denkbeeldige klant die maandag een advertentie ziet en dinsdag zonder klik iets koopt. Een geschikte weergaveconversie kan meetellen in het ene rapport en ontbreken in een vergelijking met alleen klikken. De bestelling blijft dezelfde. Een andere datumbasis kan het toegeschreven resultaat bovendien naar een andere dagrij verplaatsen. Geen van beide wijzigingen cre\u00ebert een nieuwe klant.<\/p><\/section><section aria-labelledby=\"section-nl-3\"><h2 id=\"section-nl-3\">Maak een vergelijkbare reeks<\/h2><p>Bewaar de oorspronkelijke export en vraag oudere en nieuwe perioden vervolgens op met identieke instellingen. Leg accounttijdzone, conversiedoelen, exportmoment en datumbasis vast. Beoordeel uitlevering afzonderlijk: vertoningen, klikken en uitgaven veranderen niet door deze update. <sup><a href=\"#ref-nl-1\" aria-label=\"Bron 1\">[1]<\/a><\/sup> Vergelijk aankopen met het ordersysteem en houd rekening met attributiebereik en verwerkingsvertraging.<\/p><\/section><section aria-labelledby=\"section-nl-4\"><h2 id=\"section-nl-4\">Verklaar de breuk voordat je budget wijzigt<\/h2><p>Markeer de definitiewijziging in dashboards en managementrapportages. Kun je een ouder rapport niet exact reconstrueren, toon dan de onderbreking in de reeks. Koppel de perioden niet stilzwijgend aan elkaar. Gebruik voortaan vaste instellingen en onderzoek de commerci\u00eble werking afzonderlijk. Een ruimer venster kan meer resultaten toeschrijven aan advertenties, maar bewijst niet dat die advertenties de extra aankopen veroorzaakten.<\/p><\/section>\n<details class=\"a4e-sources\" open><summary>Bronnen en onderbouwing<\/summary><ol><li id=\"ref-nl-1\"><a href=\"https:\/\/developers.openai.com\/ads\/api-overview\" rel=\"noopener\">OpenAI Advertiser API overview and changelog<\/a><\/li><li id=\"ref-nl-2\"><a href=\"https:\/\/developers.openai.com\/ads\/reporting\" rel=\"noopener\">OpenAI Ads reporting and attribution documentation<\/a><\/li><\/ol><p class=\"a4e-source-note\">Bronnen gecontroleerd op 4 oktober 2026.
