Backlinking Add-on is an optional $250/month flat fee you can switch on in the Billing & Safety Cap section. The page describes it as premium off-site backlinks to boost domain authority, with the AI including contextual backlinks to authoritative external sources in every article. In the current version the toggle only changes what is billed — it adds $250 to the subscription total and to the Stripe subscription description, and is stored on your schedule — but it has no effect anywhere in the actual article-writing prompt or the automated blog generation code. Any off-site backlink work is delivered by Sprwt's marketing team rather than by an automatic change in the generated articles. Turn it off and save to remove the charge from the subscription.
