What Is an SEO Backlink Gap Analysis?

An SEO backlink gap analysis is a subtraction. Take every site linking to your competitors. Then take every site linking to you. Whatever sits in the first list and not the second is the gap.

Running one is straightforward. Pick a few competitors. Open the report your tool calls a link intersect. Filter what comes back by authority. Whatever survives becomes an outreach shortlist. All of that is covered properly elsewhere on this site, so none of it gets repeated here.

So this page is about none of the method. Instead it is about a column.

A Backlink Gap Report Has Two Columns

The report comes back as rows. Each row holds a domain. Now open one of those rows, or export the links behind it. Something else is sitting there. The page that link points at.

One column names who linked. Then the other names what they linked to.

Only one of those columns looks like work.

The Domain Column Looks Like a To-Do List

Read down it and you have names. Names get counted. They get sorted. Above all, they get emailed.

So the domain column reads like a queue. And a queue asks to be worked through.

Yet consider what a domain actually hands you. An address. Somebody, somewhere, wrote your competitor down. Nothing in that address carries the reason.

Two rows can look alike while nothing about them is alike. One is a write-up somebody spent an afternoon on. Another is a directory entry that took a stranger eleven seconds. Same shape of row either way. Nothing in the domain separates them.

The Other Column Is a List of Causes

Now read across instead.

Every link on that report happened. Something got done. Then somebody else wrote it down. Whatever got done is sitting in the second column, in plain sight, a few hundred times over.

A study with a real number in it. Or a calculator nobody else bothered to build. Then a page about a bylaw that changed last spring. Somebody’s post about how a job went wrong.

Each of those is an answer to a question you cannot put to anybody. What does a person in this trade write a link down for?

It is not a question anybody can answer for you. Meanwhile the second column has been answering it all along.

You Cannot Study Your Own Backlinks

Try it and two things stop you.

There are too few of them. That is the first. Read your whole profile in an afternoon and you have still read too few to show you a pattern.

Then the second, which is worse. Every one of them exists for a reason you already know. You were there. Nothing in your own profile can surprise you, because you supplied all of it.

The gap report is the opposite. Several hundred rows. None of them yours. Every one caused by something a business rather like yours went and did. On a day. For reasons that had nothing to do with you.

So it is the largest body of evidence you are likely to get about the thing you are trying to cause.

Somebody Will Say This Is Copying

Fair enough. Only look at what actually repeats.

Go across a hundred rows and what turns up again is rarely an asset you could lift. It is a reason. Something the people who hand out links in your market respond to.

And it may well surprise you. The standard answer is that original research earns links, which is true and sits on this site already. Yet your report is not about the industry. Rather it is about your trade, in your city, over the last few years.

Maybe it confirms the standard advice. Then you have confirmation nobody could have sold you.

Or maybe it points somewhere odd. A page nobody would have commissioned. Then you have found something no guide was going to hand you.

Where the Backlink Gap Argument Stops

The domain column is not useless. That outreach shortlist is real work and it pays. A site that has already linked to this subject is a better ask than a stranger who never has. Nothing here argues against making the list.

Then some rows have no readable cause at all. A scrape. Or a friend of the founder. Perhaps a profile page somebody filled in years ago and forgot. Read across those and nothing comes back, which is worth knowing too.

And the second column tells you what got made. Never that you can make it. Reading a report has never moved a ranking on its own. Same goes for a keyword gap report for ads, useful and inert at the same time.

Read Your Backlink Gap Report Across, Not Down

Take twenty rows. Ignore the domains entirely.

Open the page each of those links points at. Then put one question to it. What did somebody have to do to cause this?

Answer it for most of the twenty and you are holding a list of causes. Drawn from your own market. Nobody sold you that, and no tool assembled it.

Draw a blank on nearly all of them and you have learned something as well. The report is far shorter than it looked. Most of what you were about to email was noise.

No statistic about other people’s link profiles settles which of those you are looking at. Yours is one export away.

Working With SEO Company To-The-TOP!

A backlink gap report turns up often enough at To-The-TOP!, and it is the domains that have been marked up. Often the first useful hour goes on the other column.

To-The-TOP! has been doing this work in Calgary since 2007. Solo, so the person reading your report is the person doing the search engine optimization afterwards. No junior handoffs. White Hat only, which matters a great deal on a page about links.

The work runs alongside keyword research. Sometimes a Google Ads campaign, where the timing suits. Underneath all of it sits the ordinary business of making pages worth finding. The portfolio shows the keywords this work has reached. No guarantees. Positions tend to move over three to six months. Nothing here gets bought, which is usually what triggers a search penalty. A proper competitor analysis usually starts in that other column too.

Frequently Asked Questions

What is a backlink gap analysis in SEO?

It is a comparison. A tool lists the sites linking to your competitors, sets that against the sites linking to you, then reports the difference. The output is a list of domains. What the output is used for is a separate question, and a more interesting one.

How many competitors should a backlink gap analysis use?

Enough that the same domains start appearing more than once. A single competitor gives you their history rather than your market. Three or four is plenty, and the overlap is the part worth reading.

Is a backlink gap report an outreach list?

That is how it gets sold. It works as one, and the shortlist is worth building. Only the report holds a second thing, which is a record of what those sites were willing to link to. Nothing in an email fixes a business with no content worth linking to.

Does a backlink gap analysis tell you how many links you need?

No. It tells you how many your competitor holds that you do not. So that is a different number, and a less useful one. Those links took years to arrive. Meanwhile a row count hides all of it.

Which tool runs the best backlink gap analysis?

Whichever one you already pay for. Each of them will show you the page a link points at, once you go and look. That is the whole of what this page has asked for. So the reading matters more than the export.
