Semrush's free version is genuinely useful for B2B industrial companies as a directional research tool — not a replacement for professional SEO. Ten keyword searches per day is enough to validate content decisions and spot competitor visibility. The part most guides skip: in B2B industrial markets, raw keyword data is often misleading. The filtering step — removing terms that look relevant but refer to different products in different industries — is where the real work happens. That process is hard to automate and usually requires someone who actually knows the product.

The Context — One Person, One Manufacturer, Multiple Markets
The setup is probably familiar to a lot of B2B industrial marketers: one person handling the majority of digital marketing for a manufacturing company, no dedicated SEO budget, an agency partner who handles paid advertising and joins occasional strategy sessions, and a product line that is genuinely technical and genuinely niche.
The markets are primarily Nordic — Finland, Sweden, Norway — with growing visibility into Germany and some US presence. The content is product-focused. The goal of keyword research is not to build a content farm. It is to make sure that the pages we're publishing have a realistic chance of being found by the right people, and that we're not missing obvious gaps where competitors are visible and we aren't.
In that context, Semrush's free version is the tool that covers the research layer. Not because it's perfect — it isn't — but because it provides enough directional data to make informed decisions without requiring a monthly subscription that would be hard to justify to management for occasional research use.
The agency partner has a full Semrush licence. That's where the deeper analysis happens when it's needed — keyword gap analysis, backlink audits, historical trend data. The free version handles the day-to-day checks that come up between sessions: a quick competitor visibility check, a keyword volume estimate before committing to a content piece, a position check on a specific page.
What Semrush Free Actually Includes
Most Semrush articles lead with the paid plan features. This one starts with what's actually free, because that's what most B2B industrial marketers are actually working with.
| Feature | Free limit | Where it runs out |
|---|---|---|
| Keyword searches | 10 per day | Any active research day |
| Domain analytics lookups | 10 per day | Competitor research sessions |
| Position tracking | 10 keywords | Immediately for most sites |
| Site audit | 100 pages | Any real company website |
| Backlink data | Very limited | First click usually |
| Historical data | Not available | Always |
| Keyword database access | Yes — with daily cap | After 10 searches |
Ten keyword searches per day sounds restrictive until you understand how the research actually works in practice. A single Semrush keyword search returns the target keyword plus related terms, questions, and variations. One search on a broad product term can surface 50-100 related keywords in the results panel. For occasional directional research, this is workable.
The position tracking limit of 10 keywords is the most practically limiting constraint. Most B2B industrial sites need to track at least 20-30 priority terms. For ongoing tracking at that scale, Google Search Console fills the gap — it shows real position data for every query your site actually appears for, with no limits.
💡 The free tier reset: Semrush's free limits reset at midnight UTC each day. If you plan your research sessions around this — doing one focused session rather than spreading searches across the day — 10 searches goes significantly further than it sounds.
The Part Most SEO Guides Skip: Filtering Wrong Product Terms
Here is the part of B2B industrial keyword research that almost no SEO tool or guide adequately addresses: the raw keyword data is frequently wrong for your use case, and the filtering process is where most of the real work happens.
In B2B industrial markets, technical terminology overlaps across industries in ways that create significant noise in keyword research. A term that is highly relevant to your specific product category may be primarily searched by companies in a completely different sector, at a consumer level, or in a context that has nothing to do with your product — despite looking relevant on paper.
The volume number tells you how many people search for a term. It tells you nothing about whether those people are looking for what you make.
"In B2B industrial keyword research, a keyword with 500 monthly searches might have zero relevant searches for your specific product — because 490 of those searches are from a different industry using the same terminology. The volume number is the starting point, not the answer."
The filtering workflow in practice
The European Angle — Nordic and DACH B2B Realities
Semrush's data is strongest for the US and major Western European markets. For B2B industrial research targeting Finnish, Swedish, Norwegian, or smaller German regional markets, there are specific limitations worth understanding before drawing conclusions from the numbers.
Search volumes in Nordic B2B are genuinely low. A product category with 2,000 monthly searches in the US might have 50 monthly searches in Sweden and 20 in Finland. These numbers aren't wrong — they reflect real market sizes. The mistake is treating low volume as low opportunity. In B2B industrial markets, 20 monthly searches for a highly specific product term can represent significant commercial value if those 20 searches are from procurement managers at target companies.
Zero volume doesn't mean zero searches. Semrush has a reporting threshold — terms below a certain volume level show as zero even when real searches are occurring. For niche industrial product categories in smaller markets, this happens regularly. Treat zero-volume Nordic terms as unconfirmed rather than irrelevant.
German B2B keyword research has its own logic. German B2B buyers frequently search in German, use compound nouns that don't exist in English equivalents, and have different content expectations. A direct translation of your English keyword list into German is usually not the right approach. The agency partner who understands both German SEO conventions and your product category is essential here — this is not a workflow Semrush free can automate.
⚠️ The localisation trap: Semrush's default database is US-focused. Always switch the database to the relevant country when researching European terms. A keyword showing 1,000 searches in the US database might show 40 in the Swedish database and 0 in the Finnish database — and all three numbers are correct for their respective markets.
Semrush Free vs Google Search Console — What Each Actually Tells You
These two tools are frequently compared as alternatives. They are not alternatives — they answer different questions and are most useful together.
Google Search Console tells you what is already happening on your site. Which queries trigger impressions, which pages rank for which terms, what your actual click-through rates are, and where you have positions that could move with content improvements. This data comes directly from Google and is completely accurate for your site. It is the highest-priority SEO tool for any B2B site that is already indexed and receiving some traffic.
Semrush free tells you what is happening outside your site. What competitors rank for that you don't, what keyword opportunities exist that your current content doesn't cover, and what the broader search landscape looks like for your product category. It is a discovery tool, not a performance measurement tool.
For a B2B industrial company at the early stage of content development, Search Console and Semrush free together cover the essential research layer. Search Console shows where you are. Semrush shows where you could be. The agency session is where these two pictures get combined into an actual content and optimisation plan.
When to Upgrade and When Free Is Genuinely Enough
The honest answer depends entirely on your content production volume and how central SEO is to your traffic strategy.
Free is genuinely enough when: you publish 2-4 pieces of content per month, you have an agency partner handling deeper analysis when needed, your primary traffic driver is direct and referral rather than search, and you use Search Console for ongoing performance monitoring.
Upgrade to paid when: you need historical keyword trend data to understand whether a market is growing or declining, you want to track more than 10 keyword positions consistently, you need competitor content gap analysis at scale, your content production increases to weekly publishing, or SEO becomes a primary traffic acquisition channel rather than a supplementary one.
For most B2B industrial marketing teams in the situation described here — one person, technical product, European markets, occasional research needs — the free tier combined with Search Console and periodic agency sessions covers the essential workflow. The $139/month Pro plan becomes justifiable when the content volume and SEO sophistication genuinely require it, not before.
There is also a middle path worth considering: rather than paying for your own Semrush subscription, ensuring that the agency partner relationship includes structured keyword research sessions where their full licence is used collaboratively. This is covered in more detail in the Semrush agency access vs own licence article.
Semrush free is a legitimate research tool for B2B industrial companies — not a compromise. The 10-search daily limit shapes how you use it rather than preventing you from using it. The more important constraint is not the tool limit but the filtering step: keyword data for technical industrial products requires product knowledge to interpret correctly, and no paid tier removes that requirement. Use Semrush free to find the candidates. Use your product knowledge and Search Console to validate the shortlist. Let the agency handle what genuinely requires their full licence.
