How to Use Surfer SEO to Optimise Content While You Write
It analyses what's actually on the ranking pages and hands you a live audit list instead of SEO guesswork — plus the real difference between an audit checklist and a ranking machine.
Beginner7 min read
What you'll be able to do by the end
- Understand that Surfer turns SEO guesswork into a concrete checklist: it analyses the pages actually ranking for your keyword and gives live targets — headings, terms, length — as you write
- Learn to close topical gaps before chasing keywords, and stop at a score of 70–80 — that's what moves rankings, not keyword stuffing
- Do the real cost math: no free plan, and the cheapest plan is $79/month (annual billing) for just 30 content-editor articles
- Treat weaker-market keyword data as structural guidance, not exact numbers, and verify it against a second source before deciding anything
- Know how it differs from Semrush (keyword selection versus the page content itself), and when the cheaper combo works: ChatGPT writes, Surfer audits before publish
Before you start
- A site or blog publishing content regularly that you want to actually rank, or a Google Docs or WordPress account to connect
- A clear monthly budget — there's no free plan and the cheapest tier starts at $79/month
If you’ve ever finished an article wondering “did I cover everything, or am I missing something important?” — that’s precisely the narrow question Surfer SEO answers brilliantly: what’s actually on the pages ranking for your keyword, and what’s missing from yours. It analyses the top results, then hands you a live audit list while you write — subheadings to cover, terms to add, an approximate target length. SEO stops being guesswork and becomes something you can verify.
But that same narrowness is its limit. Surfer won’t tell you which keyword to target in the first place, won’t guarantee higher rankings however high you push the score, and its keyword data outside English is clearly weaker. On top of all that, there’s no free plan to trial before committing — the cheapest tier starts at $79/month.
This guide shows you when subscribing genuinely pays off, and when the smarter move is a cheaper combination: ChatGPT writes the draft, Surfer audits it before publication.
The steps
The steps below follow the actual order of work: picking the keyword, analysing competitors before writing, the writing itself, prioritising within the checklist, and finally auditing old articles instead of rewriting everything.
Steps
Step 1: Fix your target keyword before writing a word
Sign in at surferseo.com and enter the keyword you want to write about. This is the foundation everything else builds on — the tool doesn't give generic advice; it gives analysis specific to that keyword. Choosing it well before you start matters more than any technical setup later.
Note: Haven't picked a keyword yet? That's not Surfer's job — step back to a keyword research tool like Semrush first.
Step 2: Let it analyse the current search results before you write anything
Before opening the editor, Surfer analyses the top results actually ranking for your keyword right now — not static general SEO advice, but real analysis that changes per keyword. Out of that comes your working list: terms under-used in your draft, subheadings most competitors share, and an approximate target length.
Note: If the suggested length looks inflated, ignore it. Sometimes ranking pages are long because they're padded with filler, not because length itself causes the ranking.
Step 3: Write inside the live content editor, or paste a draft you have
You can write directly in Surfer's editor and watch the score move as you type, or paste a finished draft to get an instant score on it. The tool also integrates with Google Docs and WordPress, so you don't need to change how you write — just add an audit layer over what you're already doing.
Note: A cheap combination that genuinely works: let ChatGPT write the first draft, then run Surfer as the pre-publish check only — instead of composing from scratch inside it.
Step 4: Work on topical gaps first, keywords second, and stop at 70–80
Prioritise by the checklist: cover the missing subtopics first, because closing a whole topical gap moves rankings far more than keyword density does. Getting from a score of 40 to 70 usually means you've genuinely covered the topic. Pushing from 85 to 95 usually means wedging words into text that reads worse — and Google ranks the page readers want, not the highest number in Surfer.
Note: Always stop at 70–80. Trying to exceed that typically damages writing quality more than it helps ranking.
Step 5: Audit old articles that slipped instead of writing from scratch
If you have long-published posts losing their positions, run the Audit tool on them rather than starting a new article from zero. Fixing a decent article already sitting at position ten is faster and cheaper than writing a brand-new one, and the same analysis shows exactly what changed or went missing among competitors since you published.
Note: Always start with previously ranking articles that dropped — they're far likelier to recover quickly than a piece that never ranked at all.
Common mistakes — and how to avoid them
MistakeChasing a score of 95 believing it guarantees higher rankings.
Do this insteadStop at 70–80. A very high score usually means stuffed keywords that hurt readability, and Google ranks what readers want — not the tool's highest number.
MistakeSubscribing because you're a blog publishing one or two posts a month.
Do this insteadThere's no free plan and the cheapest tier is $79/month for 30 editor articles. At low volume, the per-article cost is hard to justify — the tool makes sense at regular publishing scale (an agency or weekly team).
MistakeBuilding an entire content plan on weaker-market search-volume numbers without verification.
Do this insteadNon-English keyword data is clearly weaker than English data. Treat it as guidance for structure (headings, topic coverage), and verify any important figure with a second source before building a decision on it.
MistakeExpecting the tool itself to lift your rankings or fix a weak site foundation.
Do this insteadSurfer removes exactly one obstacle: not knowing what's actually on the ranking pages. It doesn't fix thin content, a site with no authority, or a keyword beyond your reach — treat it as an on-page audit checklist, not a ranking machine.
❓ Frequently asked questions
Does Surfer SEO actually improve my rankings?
It doesn't guarantee that. It works as an audit checklist exposing on-page errors, not as a ranking machine. Sites already publishing decent content see real results; weak sites see almost nothing, because it addresses neither thin content nor missing domain authority.
What's the difference between it and Semrush?
Entirely different jobs. Semrush tells you which keyword to target and who competes on it; Surfer tells you what to put inside the article once the keyword is chosen. Agencies often run both together — but if you can afford only one and know your keywords already, Surfer delivers more direct value.
Is it worth the price if I'm a solo blogger?
Usually no. There's no free plan and the cheapest plan is $79/month (annual billing) for 30 content-editor articles. Publishing one or two posts a month makes the per-article cost hard to justify. It becomes logical at volume — an agency or team publishing weekly.
Is non-English keyword data as reliable as English?
No, it's clearly weaker — the sample behind the analysis is smaller and less dense than English. Still useful for guiding structure (headings, topic coverage, rough length), but verify any important local search-volume figure with a second source before building a content plan on it.
