Screaming Frog SEO Spider (Licence) review 2027

What problem does Screaming Frog SEO Spider solve?

Screaming Frog is not a competitor to the others; it is the thing you run alongside them. For technical work nothing else comes close at the price. That is the whole case for it, and it is a strong one: the desktop crawler every technical SEO actually uses finds the broken links, redirect chains and duplicate titles the cloud audits miss. On our test site it found 43 issues that the cloud audits missed, including three redirect chains. It connects to Search Console, Analytics and PageSpeed for combined reports, and it is free for sites under 500 URLs. The benefit is narrow and deep: one job, done properly, on your own machine.

How did we score Screaming Frog SEO Spider?

We scored it across five criteria for a total of 8 out of 10.

• Index size & data accuracy — 24/30. How many of our 200 known backlinks each tool found, how close its keyword volumes came to Google Ads figures, and how fresh the index was. Screaming Frog found 0/200 backlinks, because it does not index backlinks at all.
• Feature coverage — 16/25. Keyword research, rank tracking, site audit, backlink analysis, competitor gap and content tools — and which sit behind a higher tier. It has no keywords tracked on the entry plan and no rank tracking.
• Usability & reporting — 11/15. Time to a first useful answer, report building, sharing with a client. Output is a spreadsheet, not a dashboard.
• Limits & fair use — 10/10. Credits, rows per export, projects, seats, and what happens when you hit the cap. The licence gives unlimited crawling on one machine.
• Value — 19/20. Monthly price for a one-person consultancy tracking 500 keywords on five sites. At $20 a month, or £199 (about $259) a year for unlimited crawling of any size site, it is the cheapest tool in this test.

What does Screaming Frog do better than anything else?

The measured result is the story. On our test site it found 43 issues that the cloud audits missed, including three redirect chains. Cloud crawlers sample and summarise; a desktop crawler with your own memory behind it goes through every URL. It also connects to Search Console, Analytics and PageSpeed for combined reports, so crawl data sits next to the numbers Google actually recorded. And it is free for sites under 500 URLs, which means a small site can run the same audit a large one pays for.

What is in the licence, and what does it run on?

The entry plan is 20 USD/mo. The free plan covers 500 URLs. Keywords tracked on the entry plan: none — not a rank tracker. Backlinks found in our test: 0/200. Site audit: yes, unlimited on licence. Local SEO: no. Seats included: 1 machine. Best for: technical audits and migrations. The licence is per machine, so a team shares one seat or buys more. Because it runs locally, a big crawl needs memory — that is the trade for unlimited crawling.

How does it compare with the tested rivals?

Against SE Ranking (8.6, $119), Screaming Frog loses on breadth: SE Ranking tracks 750 keywords on Essential and 2,000 on Pro, found 132/200 backlinks, includes local SEO and gives three seats on Pro. Against Ahrefs (8.3, $129), it loses the backlink index outright — Ahrefs found 186/200, the biggest in the test, with a site audit of 100k pages/mo on Lite. Against Semrush (8.2, $139.95), it loses the toolkit: 500 keywords on Pro, 171/200 backlinks, site audit of 100k pages, local SEO as an add-on. Where Screaming Frog is ahead of all three is price and crawl depth: $20 against $119, $129 and $139.95, with unlimited crawling on the licence rather than a page cap.

Feature comparison: where the specs separate them

Read the shared labels side by side. Entry plan: Screaming Frog 20 USD/mo, SE Ranking 65 USD/mo, Ahrefs 129 USD/mo, Semrush 139.95 USD/mo. Free plan: Screaming Frog 500 URLs, SE Ranking no (14-day trial), Ahrefs Webmaster Tools for own sites only, Semrush 10 requests/day. Keywords tracked on entry plan: Screaming Frog none, SE Ranking 750, Ahrefs 750, Semrush 500. Backlinks found in our test: Screaming Frog 0/200, SE Ranking 132/200, Ahrefs 186/200, Semrush 171/200. Site audit: all four yes, but Screaming Frog is unlimited on licence while Ahrefs and Semrush cap at 100k pages. Local SEO: Screaming Frog no, SE Ranking yes, Ahrefs no, Semrush yes as an add-on. Seats included: Screaming Frog 1 machine, SE Ranking 3 on Pro, Ahrefs 1, Semrush 1.

Where does Screaming Frog fall short?

Scope. No keyword data, no rank tracking, no backlinks — it does one job. If you need keyword volumes or a link index, this is not the tool and no licence tier fixes that. It runs on your machine, so a big crawl needs memory. And the output is a spreadsheet, not a dashboard, which means client-ready reporting is work you do yourself.

Is Screaming Frog worth the price?

At $20 a month it is the cheapest entry plan in this comparison, and £199 (about $259) a year buys unlimited crawling of any size site. The value score of 19/20 reflects that: for a one-person consultancy the licence costs a fraction of the cloud subscriptions and does the crawl work they cannot. The catch is that you still need one of those subscriptions for keywords and links, so the $20 is an addition to your stack, not a replacement for it.

Who should buy Screaming Frog SEO Spider?

Anyone doing a technical audit or a site migration. That is the buyer: the consultant or in-house SEO who needs every URL checked, redirect chains traced and duplicate titles listed, and who is happy to work from a spreadsheet. If you need rank tracking, keyword research or backlink data, buy one of the cloud tools instead — or alongside.
