Which plan to pickProfessional is the plan most teams settle on, because Starter's 10 articles a month runs out quickly. Try the 7-day trial on two or three real articles before paying.There's one plan and it's free. Microsoft says it's free forever with no traffic limits. Install the tag through Shopify, WordPress or Google Tag Manager and it starts recording within minutes.Discovery is enough if you publish a couple of posts a week. Standard is the sensible pick for a team because it adds collaboration and triples the document count.
