Semrush Link Building Tool, and the part it cannot do for you

The short answer

The Link Building Tool generates prospects from your keywords and competitors, then gives you a pipeline to organise, contact and monitor them, with email sent from a connected mailbox. Prospecting is the part that was already easy. What it cannot do is give you a reason for somebody to link, which is the only step that decides whether any of this works.

What the tool is: find prospects, organise them, then contact and monitor them in a pipeline. The three verbs are worth noting because only the first is automated. Watch from 0:13

Every link building tool sells the same thing: a big list of prospects. And prospects have never been the bottleneck.

Anyone can produce five hundred sites that theoretically might link to them. The bottleneck is that four hundred and ninety of them have no reason to, and the tool cannot invent one. What Semrush’s Link Building Tool actually does well is the unglamorous half: keeping track of the ninety you contacted.

The three things it does, ranked by usefulness

The tool describes itself as find prospects, organise them, then contact and monitor. That order is backwards in terms of value.

Monitoring is the best part. You get status per prospect: not contacted, in progress, rejected, won. At any real volume, outreach dies from disorganisation rather than from bad targeting. You lose track of who you emailed, follow up with someone twice, forget the one who said “maybe next quarter”. A pipeline fixes that, and this is a competent pipeline.

Contacting is genuinely convenient. Connect a mailbox to the project and you send from inside the tool, with replies landing in the same view. One place instead of a spreadsheet plus an inbox plus a reminder app.

Prospecting is the weakest part, and it’s the part that’s marketed. You seed it with keywords and competitors, it looks at who links to sites ranking for those terms, and it hands you a list. The list is fine. It is also the same list every one of your competitors generated from the same inputs.

Get your prospects somewhere better

Use Backlink Gap instead, then import.

The difference is a qualification signal. A generated prospect is a site that might be relevant. A Backlink Gap result is a site that has already linked to two or three of your direct competitors. That site has a demonstrated editorial willingness to link to a company like yours. It has done it before, on purpose.

Pitching somebody who has linked to three of your rivals is a different conversation from pitching a site that appeared in a list because it once mentioned your keyword. Same amount of work, materially different reply rate.

So the workflow that actually performs: Backlink Gap for the list, Link Building Tool for the pipeline. Use each for the half it’s good at.

The part no tool touches

Here’s the honest limit, and it’s worth stating because a pipeline full of prospects feels like progress.

Every link comes from a person deciding that linking to you makes their own page better. Nothing in any software affects that decision. Your reply rate is determined by what you’re offering: original data, a genuinely better resource, a correction to something they published, a mutual audience. If the answer to “why would they link” is “because I asked”, the tool will faithfully track four hundred rejections.

That is not a criticism of Semrush. It’s a reason not to buy a tier for this feature. If you are tracking outreach in a spreadsheet today and doing real volume, the pipeline earns its place. If you are hoping a prospect list will produce links, the missing ingredient is not software.

Watch the plan limits

The Link Building Tool is a project tool, which means it consumes project and campaign allowances that scale with your tier, the same way Site Audit and Position Tracking do. An agency running outreach for eight clients is spending plan capacity on this, not just time. Worth checking against what your tier actually allows before committing a workflow to it.

The workflow I’d actually run

Four steps, and only one of them happens in this tool.

One: get the list from Backlink Gap. Your domain against three or four real competitors. Export the referring domains that link to two or more of them and not to you. That “two or more” filter is the whole trick, because a site that has linked to several of your rivals is demonstrably interested in your category rather than accidentally relevant.

Two: qualify by hand. Open twenty of them. Most will be unreachable, dead, or link farms. What survives is a real list, and it’s always smaller than the export suggested.

Three: work out the reason before you write anything. Per prospect, one sentence on why linking to you improves their page. If you can’t write that sentence, remove the prospect. This is the step that determines the outcome and no software participates in it.

Four: import to the Link Building Tool and run the pipeline. Now the tool does what it’s good at: sending, tracking status, reminding you to follow up, and keeping the whole thing out of a spreadsheet that goes stale.

Steps one to three are the work. Step four is the admin. Buying the tool expecting it to cover steps one to three is why most people conclude link building tools don’t work.

Questions

How does the Semrush Link Building Tool find prospects?

From the keywords and competitors you seed it with. It looks at who links to sites ranking for your terms and who links to the competitors you named, then assembles that into a list you can work through.

Can I send outreach emails from Semrush?

Yes, by connecting a mailbox to the project. That keeps sending, replies and status in one place rather than split between a spreadsheet and your inbox, which is the genuine convenience here.

Is the Semrush Link Building Tool worth using?

As a pipeline, yes, if you are doing outreach at any volume and currently tracking it in a spreadsheet. As a source of links, no tool qualifies. The reply rate is set by what you are offering, not by where the list came from.

What is better than the Link Building Tool for finding prospects?

Backlink Gap. Sites that already link to two or three of your competitors have demonstrated willingness to link to something in your category, which is a stronger signal than appearing in a generated list.
