What It Does

What Protuno Does With Semrush.

Protuno pulls the reports your Semrush key already has access to, so it can flag ranking, backlink and competitor changes. Nothing is written back to Semrush and no new Semrush projects are created.

Keyword tracking

Lists keywords a domain ranks for in Google's top 100 organic results, with position, search volume and traffic share, so drops can be caught early.

Reads

Backlink health

Reads the summary count of backlinks, referring domains and referring IPs for a domain to catch sudden authority loss.

Reads

Competitor watch

Lists domains competing for the same organic keywords as a domain, so new competitors in search results can be flagged.

Reads

Keyword research

Pulls search volume, CPC, competition level and the number of organic results for a single keyword in one regional database, to help prioritise content fixes.

Set Up · 5 steps

You See The Full List Before Anything Is Granted.

How it connects: you paste your own Semrush API key. Use a v3 key for the older reports and a v4 key for the newer Backlinks and Keyword reports. You find it under Subscription info > API Units in Semrush. There is no sign-in step and no scope setting, so the key carries your account's full API unit balance.

  1. Step 1

    Get your Semrush API key

    In Semrush, go to Subscription info > API Units at semrush.com/accounts/subscription-info/api-units/.

    You need a plan with API access and a purchased API unit package. Copy your API key from there.

    you see: Semrush shows the active key once you have bought an API unit package.

  2. Step 2

    Paste the key into Protuno

    Pick Semrush as the data source and paste the API key.

    you see: A short field asking for the key. Nothing is contacted yet.

  3. Step 3

    See what it can do

    Protuno checks that the key works, then shows the reads and writes available.

    you see: Reads on the left: rankings, competitors, backlinks and keyword data. On the right, no writes are available.

  4. Step 4

    Choose what runs

    Reads run on their own.

    There are no writes for this connector, so nothing waits for your yes.

    you see: A row for each read, all running on their own.

  5. Step 5

    Confirm what you grant

    Confirm    Protuno states the grant as one plain sentence and you agree to it.

    you see: A sentence naming the reads granted, and a confirm button.

Before You Connect It

Questions.

What Semrush plan do I need for API access?

Semrush ties API access to a paid plan and a separate package of API units. Its developer docs name the Business plan of the SEO Toolkit, and its pricing page may name the plan differently, so check both before you buy.

What is the rate limit?

Semrush's API usage restrictions page says up to 10 requests per second and up to 10 simultaneous requests per account, across all Standard API methods.

How are API units billed?

Most SEO reports are billed per line of response, and historical data costs more than live data. For example, the Domain Organic Keywords report costs 10 units per line live and 50 per line historical.

What can't Protuno do in Semrush?

This connector is read only. It cannot create or delete Semrush projects, or manage your API key or units.

How fresh is the data?

Organic keyword data can include daily rankings for the last 31 days and monthly history further back. Each read asks Semrush at the moment Protuno needs it.

A read keeps failing. What is the common cause?

The most common cause is a depleted API unit balance. Semrush requests fail once the account's purchased units run out, so Protuno reports a pull failure until more units are bought.

Capability names and default settings (on its own or ask first) are Protuno's own, and they can change as the product develops. Playbook plan, schedule and date come from Protuno's agent pages. Protuno last confirmed this connector's build status on 13 Oct 2026. Vendor limits and permissions on this page follow the vendor's public documentation as reviewed on 13 Oct 2026. The vendor's own page is the final word.
