Tools worth your time.

I spend my working life deciding which providers deserve to be in front of a buyer. Same standard here: every entry says what it is actually good for, and what it is not, and each category is ordered so the first one is where to start. Nothing on this page is paid for, and nothing here is affiliate-linked. The reasoning behind the AI entries is inbuilding for answer enginesand where the budget goes across SEO, AEO and GEO; the books are the longer-form version of the same shelf.

AI

The tools worth actually learning, rather than the hundred wrappers built on top of them.

  • Start here

    The one most of your customers are using, which is reason enough to know it well. It is a search engine now too, and that increasingly decides who gets found.

    Not for Equally confident on what it has wrong. Treat the output as a draft argument, and never as a citation.

  • Claude (opens in a new tab)

    AssistantFree tier

    The strongest of the general assistants for long documents, and for anything where the writing has to sound like a person wrote it rather than a template.

    Not for Reasons well and still needs checking against the original on anything you would have to defend in public.

  • NotebookLM (opens in a new tab)

    Research assistantFree

    Point it at your own documents and it answers only from those. Easily the most practical tool here for anyone drowning in contracts, reports or transcripts.

    Not for Will not reach outside the documents you give it. That is the whole feature and also the whole limit.

  • Perplexity (opens in a new tab)

    Answer engineFree tier

    Cites its sources, which the others still do badly. Use it for research you intend to defend, and to see how an answer engine actually summarises your company.

    Not for The citations are the point, so read them. Its summaries still compress the nuance out of a source.

  • Free access to Gemini with a very large context window. The fastest way to test whether an idea works at all before anyone signs off on a subscription.

    Not for A developer playground rather than a product: no team accounts, no sharing, no governance around it.

AI visibility

Being found by an answer engine is not the same job as ranking in a search result, and it is early enough that the tooling is mostly free.

  • Start here

    Peec AI (opens in a new tab)

    AI answer trackingPaid

    Tracks whether your brand actually appears in AI answers, how you place against competitors, and which sources the engines cite. The measurement the rest lack.

    Not for Not rank tracking or keyword research. Self-serve plans watch three engines; the rest are paid add-ons.

  • Schema.org (opens in a new tab)

    Structured data referenceFree

    The vocabulary search engines and AI systems read to work out what a page is about. Unglamorous, and increasingly the difference between quoted and ignored.

    Not for A vocabulary, not a tool. It tells you what is valid, never whether your pages actually emit any of it.

  • Shows what a crawler actually parses out of a page rather than what you believe you published. The fastest way to prove your markup does what you think.

    Not for Checks Google's requirements only. A pass here says nothing about how other engines read the page.

  • Worth setting up because several answer engines lean on Bing's index rather than Google's. Ten minutes, free, and it covers a side nothing else shows.

    Not for No substitute for Search Console. The traffic numbers are small; the indexing data is why you are there.

  • IndexNow (opens in a new tab)

    Change notificationFree

    Tells participating engines a URL has changed instead of waiting to be crawled. Trivial to implement, and it shortens the gap between publishing and being seen.

    Not for Notification, not persuasion. It will not make anything rank, and Google does not currently use it.

Digital marketing

Almost everything you need to diagnose a visibility problem is free. The paid tools mostly save time, not answers.

  • Start here

    First-party data straight from Google on what you rank for and what people actually clicked on. If you only ever set up one thing on this list, set up this one.

    Not for Google only, and the data lags by a couple of days. It tells you what happened and never why it did.

  • Session recordings and heatmaps, genuinely free and with no row limit. Everything else here tells you how people arrive; this one shows what they did next.

    Not for Shows behaviour, never reasons. It tells you where people give up, not why they came in the first place.

  • Runs Lighthouse against any URL, including a competitor's. Speed is both a ranking factor and a conversion factor, and this says which parts are costing you.

    Not for A lab score for one URL. Real users on real phones are slower, and the field data takes weeks to appear.

  • Crawls your site the way a search engine does and finds the broken, duplicated and unindexable pages nobody knew about. Free to 500 URLs, which covers most.

    Not for Finds technical faults, not weak content. The free limit stops at 500 URLs, where large sites get interesting.

  • Ahrefs' backlink index, free, for any site you can prove you own. The link data alone is worth the verification step, and it is the part a competitor cannot hide.

    Not for Only works on sites you can prove you own, so it is no help whatsoever for looking at a competitor.

  • Free, and it answers the question the paid platforms dress up and charge for: is interest in this growing, seasonal, or already over before you even start.

    Not for Relative interest only, never absolute volume. Good for direction and seasonality, useless for a forecast.

  • Turns one seed keyword into the questions people actually type. Better input for a content plan than a keyword list, because a question tells you the intent.

    Not for Gives you questions, not volumes worth trusting on the free tier. Treat it as a prompt, and not as a plan.

Sales

Tools matter far less here than the operating rhythm. These are the few that genuinely change what a team does.

  • Start here

    The free tier is a real CRM, not a trial. For a team with no system at all it beats a spreadsheet on day one and scales much further than most people expect.

    Not for The free tier ends exactly where marketing automation begins, and the steps up from there are steep.

  • Expensive, and still the best source of accurate B2B account and contact data. Worth it only if your team has the discipline to actually work the lists it builds.

    Not for Not a database you can export. It is a working surface, priced per seat, and it rewards discipline.

  • Apollo (opens in a new tab)

    Prospecting and enrichmentFree tier

    Closes the gap between finding a company and having a working contact record, with a free tier generous enough to judge it. The sequencing is a bonus, not the point.

    Not for Data quality varies sharply by market, and the outreach features make it easy to burn a domain fast.

  • Hunter (opens in a new tab)

    Contact findingFree tier

    Finds and verifies work email addresses. The verification is the part that matters: it is what keeps your domain out of spam folders and your list worth having.

    Not for Finds the address. It tells you nothing at all about whether the person wants to hear from you.

  • Published analysis of what actually correlates with closed deals, drawn from recorded sales calls at scale. Read it instead of another opinion piece on cold calling.

    Not for Research rather than a tool, published by a vendor whose own product the findings happen to support.

Leadership

Two things decide whether a team performs: who is on it, and how you run them. One for each, and no HR platforms.

  • Start here

    Two decades of free guidance on the mechanics nobody teaches: weekly one-on-ones, feedback, coaching, delegation. Unfashionable, very specific, and it works.

    Not for Prescriptive to a fault, and written for a corporate reporting line. Take the rhythm and adapt the scripts.

  • Lencioni's assessment of the work people are naturally good at and the work that drains them, with a team map showing exactly where a team has a hole. $25 a head.

    Not for Not a performance measure. Deciding promotions or exits with it is the one use it explicitly warns against.

Negotiation

There are no tools here, only preparation. These are the places that teach it properly.

  • Start here

    The source most negotiation advice is downstream of. The free articles cover more ground than most paid courses, and the executive programs are the real thing.

    Not for Academic in register. Strong on the principle, much lighter on what to actually say in the room.

  • The Black Swan Group (opens in a new tab)

    Training and resourcesFree tier

    Chris Voss's outfit, applying hostage-negotiation technique to commercial deals. Strong on the tactical conversation, much lighter on the structure of the deal.

    Not for Built around a single methodology. If you want approaches weighed against each other, look elsewhere.
