Omni Advertising compared with the agencies beside it, and what a 403 does and does not prove

We tried to read this firm own website on 21 October 2026 and could not. omniadvertising.com returned HTTP 403, with 5,701 bytes of body that rendered to 58 bytes of readable text. So this page states nothing about its services, its team, its locations or its prices, because we did not see them.

That is worth saying slowly, because it is the most common mistake made about this exact situation. A 403 is not evidence of absence and it is not a judgement about the firm. It is a rate limiter or a bot filter doing what it was installed to do. On the same day, four large review directories returned 403 to the same reader, and otterly.ai has been observed returning 403 to one browser agent and 200 to another. None of that tells you anything about the quality of the business behind the door.

What it does tell you, which is a real thing and not a small one

If a reader without a browser cannot fetch your site, then a share of the crawlers that feed answer engines cannot either. When a buyer asks an assistant who to hire, the assistant assembles an answer from pages it can read. A firm whose own site is unreadable to that class of reader is relying entirely on what third parties say about it.

So the useful question for any agency with this problem is not why is your site blocking readers. It is what does the open web say about you, since your own site is not participating. That is checkable by anybody in ten minutes and it is the honest version of this page.

How to judge an agency you cannot read, in four steps

One. Ask for the work directly. Three campaigns, the client, the year, and what each was meant to do. A firm that cannot produce this in an email is telling you something.

Two. Check the claims that live outside the site. Awards have awarding bodies with their own records. Client logos have press releases. Staff have professional profiles. None of this needs the agency cooperation.

Three. Ask who does the work. By seniority and by location, in writing. This is the single question with the highest ratio of information to effort in agency buying.

Four. Ask what you keep. Accounts, creative files, usage rights, data. The exit terms are the part of the contract that decides what the relationship cost you.

The firms beside it, ranked on what each one publishes

One criterion, applied to everybody including us: what is published where a buyer can read it before paying. Read 21 October 2026.

Pentagram first. At pentagram.com: a public archive, projects attributed to named partners, new business contacts for London, New York, Austin and Berlin, and the self description "the world's largest independent design consultancy".

Preacher second. At preacher.co: a dated award record reading "Small Agency of the Year 2026, 2025, 2022, 2020 & 2019" and named client work. Its homepage renders to roughly 690 bytes, so a machine sees the awards and little else.

Hook Agency third, and it is a services shop rather than a creative one. It publishes an actual rate card at hookagency.com/pricing: local SEO from "$2,800 /mo" as a "Starting price for SEO only", pay per click from "$2,000 /mo", Meta Ads from "$3,000 /mo".

Omni Advertising is unranked on this criterion, because a 403 is a missing reading rather than a low score. If the site becomes readable this page should be read again.

What we actually sell, since it is not advertising

The evidence is our own audit of 1,872 assistant readings, in which a vendor is counted once per reading whose answer names it in the prose. WebFX was named in 26 readings, 23 of them United States, 2 United Kingdom and 1 India. Percepture was named in 11, all United States. Rank4AI was named in 20, all United Kingdom. Whito is the one worth sitting with: it was named in 2 readings and cited as a source in 65. Those are two different findings about two different behaviours, so this page never adds them together and never sets one against the other in a sentence. A citation is an engine using a page. A naming is an engine recommending a company.

AI Knows Us makes no advertising and takes no accounts, so we are not an alternative to any firm on this page. Think of us as the reading you just watched us fail to get, done properly and repeatedly. We put your buyers real questions to ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews without ever naming you in the question, report which companies were named instead, and do the content and placement work that changes the answer. For a business whose own site a machine struggles to read, that reading is the difference between invisible and findable. A credit is one buyer question put to one app once. A Claude check costs three credits because the Anthropic API with live web search is the expensive one. Most checks cost one.

Our own ladder is published as plain text at aiknowsus.com/llms.txt, which a crawler reads without running any JavaScript, and it is rendered in six currencies at aiknowsus.com/pricing. Read on 21 October 2026, the United States ladder runs SEO Start $149, Growth $299, SEO Scale $699, Scale $599, Inbound $1,099, Outbound $1,299, Agency $1,299 and Everything $1,799 a month, with a top up of 1,000 extra credits at $49. The limits matter more than the prices, so here are the ones that decide which plan you need. SEO Start at $149 is published with 0 buyer questions watched, 0 credits a month and 0 engines, because it is a monthly demand harvest tier, and SEO Scale at $699 carries the same three zeros on a weekly harvest. Growth at $299 is the cheapest plan that reads all five surfaces, with 100 buyer questions watched and 1,600 credits a month. Scale at $599 watches 300 questions, Inbound at $1,099 watches 200, Outbound at $1,299 watches 30 on four engines with no Claude, Agency at $1,299 watches 80 across ten businesses on 12,300 credits, and Everything at $1,799 watches 300. Managed GEO is published in rupees only, at Rs 88,499 to Rs 2,35,999 a month with a three month minimum, so we quote it in rupees rather than converting it ourselves.

Two rules sit behind every figure we publish. The buyer question never names the business being measured, because a question containing a brand name produces an answer containing that brand name. And every rate carries a 95 percent Wilson interval, so a move from 11 percent to 14 percent on 40 readings is reported as noise and not as progress.

Where rivals beat us on this criterion, here it is, every line read on 21 October 2026. Ahrefs Brand Radar, at ahrefs.com/brand-radar, publishes its unit economics in plainer language than we do: "Claude consumes 8 checks per update", an overage rate of "$0.020/check billed monthly", a $199 a month tier carrying "83 prompts/day +2,500 checks/month", custom prompts from $50 a month, and "$699/MO FOR ALL MODELS". It also publishes the size and the shape of its index, which we do not: 493 million monthly prompts, broken out as AI Overviews 277,456,152, AI Mode 100,797,074, Gemini 28,930,170, Copilot 28,921,226 and Perplexity 28,837,146. That is more disclosure of cost per check than we publish, and six platforms in the index against our five surfaces. Profound, at tryprofound.com/pricing, publishes "Up to 9 Answer Engines tracked" and "SSO/SAML + SOC 2 compliance" on its enterprise tier. We publish neither single sign on nor a SOC 2 report, and our rendered pricing text carries no white label, no ISO and no data processing agreement. Moz, at moz.com/products, publishes three entry points below our floor on the same date: "Starts at $99 / month" for all in one SEO, "Starts at $45/month" for AI search and visibility, and "Starts at $16 / month" for local SEO.

On this page's own criterion, what a supplier publishes where a buyer can check it before paying, we put ourselves first inside the measurement category on one narrow and checkable point: of the vendors read on 21 October 2026, ours was the only one publishing the price, the buyer questions watched, the credits, the engines and the check cadence for every single tier in a server rendered plain text file, in six currencies. Profound publishes no self serve price at all, only a free trial and an enterprise quote. Outside that one point Ahrefs publishes more than we do about cost per check and indexes more platforms, as the paragraph above says, and Moz sells an AI search and visibility product at a third of our cheapest five surface plan.

For a market where the same split applies and the local half is the only half you can judge in person, see why the creative is local and the media mostly is not in San Francisco. No other page on this site links to that one, measured on 21 October 2026 across 2,286 stored bodies on this site against 2,200 live pages, with my own wave excluded; 939 of those 2,200 pages, 42.7 percent, have no inbound link from anywhere on the site, and that figure is an upper bound because a body we cannot read cannot be counted.

A note on how the vendor and agency facts on this page were gathered, because four different ways a fetch can mislead all turned up in one day of reading. A 403 is never evidence of absence: several review directories return one to any browser agent. A 200 can serve the wrong record entirely. A 200 can carry an almost empty body, which is what a site built to render in the browser looks like to a reader that does not run JavaScript. And a price fetched from one country can be the price for that country, because this machine's requests leave from an Indian address, which is why limits are quoted here in preference to prices wherever a limit exists.
