| Which plan to pick | 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. | The free version is enough for most small businesses because it includes every feature and only caps the crawl at 500 pages. Buy a licence when your site or your clients' sites go past that. The price is listed in pounds with dollar and euro options at checkout. | 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. The prices shown are for yearly billing; Surfer says monthly billing costs up to 17 percent more. |
