What Is SEO, and What Are ADA Principles?

Two jobs land on the same web team, usually inside the same week. SEO is the work of getting a page found and placed by a search engine. ADA principles are the conditions that same page has to meet before somebody with a disability can use it.

Then the part nobody says out loud. Only one of the two has a finish line.

The Short Version of Each, Then the Part That Matters

Search engine optimization means the work that gets a page ranked. Keyword research at the front. Then the writing and the structure. Links pointing in from elsewhere as well. Nothing in any of it is a rule you either meet or fail.

ADA is American law. It says nothing about websites. Not a line of it.

So the principles come from somewhere else. A technical standard called WCAG, which is what almost everybody means by ADA compliance. Four principles hold the whole standard up.

Perceivable asks whether your content reaches somebody at all. Operable is whether they can work the page once it has reached them. Understandable covers whether the thing behaves the way they expected. The fourth one, robust, asks whether it survives software nobody tested against.

SEO Has No Pass Mark. ADA Principles Are Nothing Else.

Here is the structural difference. It outlives every other comparison you will read on this.

Search work gets graded against other pages. Yours never sits against a standard. Instead it sits against whoever else wants that query. Failure is not on offer. You can only place below somebody who did more.

An ADA principle grades nothing of the sort. It puts one question to your page on its own. Can this person get what they came for? Yes or no, on that element, for that person. No competitor enters into it.

Which is why compliance and optimization describe opposite shapes of work. One has a state you arrive at. The other has a direction you travel and never finish travelling.

Run the two extremes and the point lands. A page can sit at the top of the results and fail all four principles at once. Nothing in the ranking stops it. Meanwhile another page meets every principle cleanly and ranks nowhere, since meeting them was never an argument for ranking. Neither outcome is a paradox. They are two scoreboards that nobody ever wired together.

The Overlap Is Settled. Nobody Settled the Stopping Point.

Everybody writing on this lands on the same overlap. Alt text feeds a screen reader and a crawler both. Heading structure helps each of them work out what a page holds. All of it is true. This site has been through it properly elsewhere, so none of it gets repeated here.

What nobody asks is when you are finished with a shared item.

Take the one both lists claim hardest. Your alt text. The SEO stopping rule is easy enough to state. That image has a description, worded like the page it sits on. Done. A crawler now has everything it wanted.

Perceivable stops in a different place. It stops once somebody who cannot see that image knows what it was doing there. Those two stopping points land together only when the image was decorative anyway.

Every Shared Item Has Two Stopping Points

Headings behave the same way. A crawler wants your keyword in an H2, roughly where a reader would expect to find it. Nothing more gets asked of you.

Operable wants something harder. Somebody jumping heading to heading should come away with an outline matching the page. An H2 dropped in for keyword coverage clears the first test and quietly breaks the second. None of that will ever appear in a ranking report.

Link text, again. Descriptive anchors help search, which is ordinary advice. That same principle wants the link to say where it goes when it is read with nothing around it. Read your own anchors on their own sometime. Half of them stop making sense.

Form labels close the set. A crawler barely cares about them. Understandable cares a great deal, since somebody has to be told which field went wrong and why. Nothing in that moves a ranking either.

Somebody Will Say Good SEO Work Covers Both

It does, wherever a crawler happens to be the stricter judge. So the fair question is how often that happens.

Almost never. The reason is not complicated. A crawler is working out what your page is about. Somebody with a disability is working out whether they can finish something on it. Understanding accepts less than finishing does. Every time.

So the shared items are not where the two disciplines agree. Rather they are where the weaker standard gets mistaken for the stronger one. The line comes back ticked on both lists. Only one of those lists is telling you the truth about it.

The Fourth Principle Is the One People Never Check

Three of them get argued about constantly. Number four gets skipped. Odd, since it sits closer to technical search work than anything else on the list.

It asks whether your page still functions with software nobody had in mind. Assistive tools. Old browsers. Whatever ships next year.

A dropdown built out of plain divs will render. Google renders it too. The text inside gets indexed like any other text. Meanwhile a screen reader finds no control there, since a div carries no role of its own. The text still gets read out. What never registers is the button. That markup satisfied one judge and never met the other.

Worth raising with whoever built your theme. Also worth a line in your next website audit, because markup problems tend to surface there first.

ADA Is American. The Principles Are Not.

Businesses here ask about the ADA for one of two reasons. They sell into the United States. Or somebody handed them an American checklist and nobody stopped to question it.

Either way the four principles travel. They were never written into the statute. Instead they belong to a web standard that regulators in several countries point at, this one included. Which obligations actually land on your business is a question for a lawyer. Not for this page, and not for your SEO consultant.

Sort Your Own List in One Pass

Take whichever document put both words in front of you. Then read every line on it and ask who signs that line off.

A crawler signs some of them. People sign the rest. Where both names turn up, write down the stricter stopping point, since that is the one you are actually working to.

Then count what remains once the search budget has paid for its half. That number is your real gap. No statistic about other people’s websites is going to hand it to you.

One more pass after that. Go back to the shared lines and check which stopping point your last invoice actually paid for. Most suppliers quote the search one, since that is the work they do all day. Nothing wrong with that. Only nobody tells you which of the two rules they stopped at.

How SEO Company To-The-TOP! Handles This in Calgary

An accessibility document and a search brief turn up together often enough in SEO work in Calgary. Usually somebody wants to know whether one budget can cover both.

Part of it can. The alt text. Heading structure and link text as well. Every bit of that counts as ordinary search engine optimization work and gets handled in the same pass as everything else.

The rest is a separate conversation, worth having on its own terms rather than smuggled into a ranking budget.

To-The-TOP! has been doing this since 2007. One person handles the account, so nothing gets passed to a junior halfway through. Keyword research first. Then the pages, then the patient part. No guarantees. Positions take three to six months to move. The portfolio shows which keywords this work has already reached. Businesses needing customers before then often run a Google Ads campaign alongside it.

Common Questions About SEO and ADA Principles

Does meeting ADA principles improve SEO?

Part of the work produces things a search engine reads, so that part was sitting on your SEO list already. How much weight it carries is not something anybody outside Google can settle. Treat the ranking effect as a side benefit rather than the reason.

What are the four ADA principles for websites?

Perceivable comes first. Then operable, then understandable. The fourth is robust. All four come out of WCAG rather than the ADA text itself, which never mentions the web at all.

Does the ADA apply to my Calgary business?

It is United States law, so Canadian businesses answer to Canadian requirements instead. Which ones depend on where you operate and who you sell to. Ask a lawyer rather than an SEO. What does travel is the standard underneath, since the same four principles get referenced on both sides of the border.

Can an SEO audit tell me whether my site is accessible?

No. It answers a different set of questions and stops at a different point. An accessibility test gets run against your page by somebody using it, or by software imitating that. Neither one is looking at where you rank.

Which accessibility work should come out of the SEO budget?

Whatever produces text somebody can read. That work does two jobs at once. Keyboard access and focus outlines and error messages belong on a separate line. No ranking argument is ever going to fund them.
