Start with the overwhelm, not the framework
Nobody wakes up wanting a framework. They wake up with a marketing budget that isn't working, or a site that Google stopped sending people to, or a boss who wants "an AI strategy" by Friday, and the thing they need first is to be told which problem they actually have. So this page is organised by the feeling, not by the name of the tool, because in all the years since 2006 I have never once had a client describe their problem using the name of a framework.
Read the four descriptions below and go to the one that sounds like your week.
Marketing feels like noise
This is for marketers, founders, CEOs, anyone at all who has been handed forty things to do and can't tell which two matter. Every piece of marketing advice you've ever received sits on one of two levers, and the relief of seeing that is the whole point. Traffic + Offer is where I'd start almost everyone, including people who think their problem is more sophisticated than that, because in my experience it usually isn't. The call it helps you make: before you build anything, put a minimum of traffic in front of the offer and let real people tell you whether the business works.
Search keeps changing the rules on you
If you have a website, learned SEO one way, watched it stop working, and don't know whether the fix is a new tactic or a new way of thinking, it's the second one. Opportunity + Authority takes the classic terms you were taught and rebuilds them for the AI and trust era, ending in what to do on your website now. The call: is your site's problem opportunity, being visible where people look, or authority, being credible enough to be chosen once they find you.
AI is arriving faster than your marketing can absorb it
This is for people who are being handed AI tasks and losing grip on their systems, their brand and their creative process, and for anyone who runs a marketing department and needs to understand how AI fits across all of it, the product and the pricing and the distribution, not just the copy. 4 Quadrant AI is where you decide which work you keep and which you hand to the machine, how you implement it, look after it, and stop it taking over.
You can't tell what to chase any more
Search, or AI answers, or follower counts, or the newest acronym someone sold you this month. Trust has always been how humans decide who to believe, and The Trust Algorithm traces how that got encoded, from a handshake to reviews and scores, to credentials and citations, to AI as the newest proxy, and asks how each of them is assessed. It is the theory underneath the other three sites, and it will never once tell you what to do on Monday.
Or sort by who you are instead
Some people would rather not read four descriptions looking for themselves, which is fair enough, so here is the shorter route. If you run a small business and you need marketing to produce revenue rather than applause, start at Traffic + Offer, where everything is written in plain language on purpose and nothing assumes you already know the jargon. If you do this for a living, if marketing or search or marketing operations is the job somebody pays you for, then Opportunity + Authority and 4 Quadrant AI both assume you arrive with the vocabulary already, and they go deeper faster because of it. And if what you want is the thinking underneath rather than something to do on Monday morning, The Trust Algorithm is the theory layer.
Every site says at the top who it was written for, and where to go if that isn't you.
After the call, the handoff
Each site helps you make one strategic call, and that is where the hard thinking ends. First break the outcome you want into its parts, traffic, offer, pricing or margin, and keep asking why until you reach the thing that actually has to change. Then you'll find that many tactics and platforms could reach it, and the choice becomes easy, not because it becomes obvious but because it becomes inconsequential. Pick by fit, your brand, your story, the tool you enjoy, and stick to it. Marketers stress about making the right decision when they only need to make one.
So each site's diagnostic ends the same way, with three doors. Do it yourself, with the pages on that site, which stay at the strategic level on purpose. Use a tool, from a page that lists more than one for each job and hands you to the maker's own guide for the how, because the tactics are theirs, not mine; The Trust Algorithm keeps no tools of its own and points you to a site that does. Or hire someone, and before you do, check whether what they learn flows back into your business, whether the channel's spend justifies paying them, and whether they will take full responsibility for one platform.
If you pick the wrong door
It doesn't matter much. They're one system seen from four distances, so the door you walked in through just changes what you read first. The story of how all four were built, the businesses they came out of and the failures that shaped them, is in the book, and the experiment is me finding out, in public, whether any of it still works.
