How to See What SEO a Company Is Using

Open their site. Right-click and view the page source. Search that code for the word yoast, then for rankmath, then for aioseo. You have an answer inside a minute.

That is the literal reply to the question. It is also close to useless.

The plugin never made a single ranking decision. A person did. Those decisions sit in public too. They just live somewhere other than the plugin footprint.

The One-Minute Scan Anybody Can Run

Start in the source code. Ctrl-U opens it in most browsers.

Search there for the plugin names. Then search for application/ld+json, which is where schema markup lives.

Now leave the source. Add /robots.txt to their domain, then /sitemap.xml. Both files are public by design.

A technology-detection extension does the same fingerprinting faster. Wappalyzer and BuiltWith read publicly visible code and name what they recognize. Neither one sees inside a paid subscription.

So the scan works fine. Run it on any site you like. Then look hard at what you are actually holding.

A Plugin Name Is Not the SEO a Company Is Using

Knowing a company runs Yoast tells you it runs WordPress. Very little else follows.

Yoast does not decide what a title should say. It gives you a field and a default template. A person still chooses the words.

Same story with the schema. Nothing different happens with the meta description either. The tool renders what a human already decided.

Novelists write in Word. Knowing that has never helped anybody write a novel.

Their Sitemap Is the Strategy Document

The sitemap lists every page a company wants indexed. That list is a budget with the dollar signs removed.

Open it. Count the URLs. Read the folder names down the left.

Forty service pages against one blog post describes a company betting on service pages. Four hundred blog posts against six service pages is the opposite bet. Neither is wrong. Both are legible from a browser tab.

Then read the lastmod dates. Identical timestamps across three hundred URLs mean a bulk re-save. Real editing leaves those dates scattered.

Count What Google Actually Kept

The sitemap shows intent. Google’s index shows acceptance. The gap between the two is where the interesting part hides.

Run a site search on their domain.

site:theircompany.ca

Google returns an estimate rather than a count, so treat the figure loosely. Still, two thousand submitted URLs against ninety indexed says something no plugin scan ever will.

Thin pages get dropped. Duplicates get folded together. A wide gap usually points at one of those two.

Read Twenty of Their Titles in a Row

Read a title tag and you are reading the visible output of keyword research. Somebody’s research, at least. Sometimes nobody’s.

Pull twenty titles straight from the sitemap and read them as a block. The pattern arrives fast. City name in every one? They are chasing local. Question format across the whole blog? They are chasing informational queries.

That pattern beats the plugin name by a wide margin. It is the shortlist a company paid to produce, then published for free. Proper keyword research costs real money and leaves its fingerprints exactly here.

Their Internal Links Rank Their Own Pages

Look at what the homepage links to inside the body copy. Skip the navigation. The nav links everything, so it prioritizes nothing.

Body links are choices. A page linked from four other pages is a page somebody decided to push.

Follow them for ten minutes and the priority list draws itself. Usually two or three pages carry the whole site.

Somebody Will Say the Real Work Is Invisible

Fair objection, and mostly true.

You cannot see the monthly budget. Nobody outside can sort the bought links from the earned ones. Maybe an agency does the work itself, or maybe a contractor overseas does it. That stays hidden as well.

Yet none of that was ever copyable. Their budget is not available to you. Neither is their agency.

The layer you can copy is the decision layer. That layer happens to be the visible one. The whole trick inside this question sits right there.

Invisible work also leaves marks. Two hundred fresh URLs inside one quarter is not a person writing. A company with no local presence last year now carries a page per suburb. You can date that decision from the sitemap.

The SEO a Company Is Using May Have Stopped Two Years Ago

A scan reports a state. It says nothing about a pulse.

So check the dates before anything else. Newest blog post. Then the newest lastmod stamp sitting in the sitemap. Copyright year in the footer, which is weaker evidence but free to read.

Plenty of sites look thoroughly optimized and have had nobody working on them since 2023. Schema in place. Clean titles. Tidy URL folders. All of it installed once, then left alone.

That distinction matters more than the tool list does. Live SEO and abandoned SEO look identical in a plugin scan. They behave nothing alike in search results.

Still worth knowing which one you found. Otherwise you copy a strategy its own owner walked away from.

Running the Same Scan on an SEO Company Itself

This is usually where the question starts. Somebody is about to sign a contract.

Point the scan at the agency’s own website. Sitemap, then titles, then internal links.

An agency with eleven indexed pages and no blog is not disqualified by it. Plenty of capable practitioners stay quiet online. Still, ask about it on the call and listen to the answer.

Check whether the same firm buys Google Ads traffic for its own service terms. That is no scandal. Most agencies run both channels and both are legitimate. It is simply another data point for the conversation.

You Are Looking for a Gap, Not a Copy

Most people run the scan and then rebuild what they saw. Wrong instinct.

A page list is a map of ground already taken. Rebuild it and you finish second on every one of those pages.

So read the list backwards instead. Which service has no page at all? Find the city that gets a passing mention and never a page of its own.

The absence is the useful finding. It is also the least contested, since nobody is defending an empty space.

Then check the dates on whatever gap you found. A topic dropped three years ago was often dropped for a reason. Plenty of dead ends in search engine optimization looked promising once.

Where the Scan Stops Short

Results stay private. Their traffic numbers never leave the building, and neither do conversions or revenue.

Rank checkers report positions for keywords you thought to type in. Meanwhile most of their traffic probably arrives on queries neither of you would guess.

So the scan tells you what a company decided. It cannot tell you whether the decisions worked. People collapse those two questions constantly, then copy a competitor straight into the same mistake.

A proper website audit separates them. One column for what a site does. Another for what it earns.

What We Look At First

SEO Company To-The-TOP! has been reading Calgary websites since 2007. Sitemap first, every time.

Titles next. Then the internal links. The plugin comes last, when it comes up at all.

Nineteen years of it and the sitemap still gives up more in five minutes than most tool reports do in fifty pages. Every piece of Calgary SEO work here opens the same way. Our portfolio is public, so point the same scan back at us.

Common Questions About the SEO a Company Is Using

Can you tell which SEO tools a company pays for?

Not from outside. Subscriptions leave no trace on a website. Plugins do, since they output code into the page itself. The rest of the stack stays private.

Is it legal to check what SEO a company is using?

Yes. You are reading published pages that a company chose to make public. Sitemap and robots files exist for machines to read. Heavy automated crawling is a separate question worth checking against their terms.

What is the fastest way to see what SEO a company is using?

The sitemap. One file gives you page inventory and publishing cadence together.

Does the SEO plugin a company uses change its rankings?

No. The major plugins output much the same tags. What goes inside those tags is a human decision, and that decision is the part that moves rankings.

Can you hide what SEO a company is using?

Partly. Comments get stripped. Plugin footprints get filtered. Titles and internal links cannot be hidden and still work, though. Anything a company conceals completely has stopped helping it rank.
