Why "how much should I spend" needs three inputs, not one
The right marketing budget isn't a fixed percentage — it depends on how established the business already is (a new business needs to buy attention it hasn't earned yet, an established one can lean more on repeat and referral), what the goal actually is (immediate leads vs. long-term brand equity vs. e-commerce sales pull very differently on the channel mix), and what industry you're in (some categories convert efficiently on high-intent search, others on visually-driven discovery feeds). This tool combines all three into a starting allocation rather than a single generic "spend 10% of revenue" rule that ignores all of that context.
The channel split is deliberately a starting point to test and refine, not a formula to follow blindly — your own campaign data should always override a generic recommendation once you have enough of it to trust. Use the Google Ads cost calculator and ad budget calculator to turn the Google/Meta portions of this split into a concrete spend-to-lead expectation, and see our full services overview for how the SEO/content portion typically gets executed alongside paid.
