LinkedIn Industries: How to Choose the Right Category

Pick the LinkedIn industry your buyers and recruiters filter by, not the one that describes your paperwork. LinkedIn’s current taxonomy holds 434 industries arranged under 20 top-level groups; every company page and personal profile gets exactly one, and the field acts as a hard filter in search. Choose the wrong category and your page is excluded from the filtered results your audience actually uses.

That makes the industry field one of the cheapest corrections available in an organic social media strategy, and one of the most commonly left on whatever LinkedIn guessed at sign-up. It takes two minutes to change and carries no penalty to followers or page authority.

For UK and Irish businesses, there is a second problem. LinkedIn’s taxonomy is aligned to the North American Industry Classification System, not to UK SIC codes or Irish NACE classifications. The labels are American, the groupings reflect a US economic structure, and several common British business types have no clean equivalent.

This guide on LinkedIn industries covers what the industry field actually is, every major category with UK mappings, how to resolve the hybrid industry problem, and what to do when nothing on the list fits.

What Does “Industry” Mean on LinkedIn?

Industry on LinkedIn is a single-choice classification drawn from a fixed list, not a free-text description of what you do. You cannot type your own. You select one entry from a controlled taxonomy that LinkedIn calls Industry Codes V2, and that selection becomes a structured filter attached to your profile or page.

The current V2 taxonomy contains 434 industries organised under 20 top-level groups, published by Microsoft as the reference list for the platform. It replaced an older flat list of roughly 149 categories when V2 rolled out in 2023. The hierarchy runs several levels deep, so “Restaurants” sits under “Food and Beverage Services”, which sits under “Accommodation Services”.

Three practical consequences follow from that structure.

It is one choice, not several. Both personal profiles and company pages allow exactly one industry. There is no multi-select, and no way to tag a second category.

It is separate for people and companies. Your personal profile industry and your company page industry are set in different places and do not sync. Changing one leaves the other untouched.

The list is currently closed. Microsoft’s own documentation states that it cannot presently accept updates to the industry codes or requests for additional industries. If your sector genuinely has no entry, that is a limitation of the taxonomy rather than something you have missed.

The Specialities field is the usual workaround for businesses that span more than one sector. It is free text rather than a controlled category, so it will not put you into a filtered search result, but it does give LinkedIn’s index additional terms to work with.

Why Your LinkedIn Industry Selection Is a Data Decision

Most company pages treat the industry field as a formality. LinkedIn treats it as a primary filter. When a recruiter searches for candidates in a specific sector, or a buyer uses a company search to find potential partners, the industry tag is one of the first filters applied. Pages outside the expected category do not appear in those filtered results at all.

How LinkedIn Uses Industry Data Algorithmically

The industry selection drives three distinct functions. First, it determines which search results your page appears in when users filter company or people searches by sector. Second, it feeds the advertising platform, which lets advertisers target audiences by industry with considerable precision. Third, it shapes the LinkedIn feed, influencing which posts and company updates your followers see from others in the same category.

For B2B businesses in Northern Ireland and the UK, that third function matters more than most people expect. If your page sits in the wrong category, your content reaches audiences with no commercial interest in what you sell. The result is low engagement, slow follower growth, and weak performance on paid campaigns.

The Difference Between Reach and Relevance

Choosing a broad category such as “Technology, Information and Internet” gives access to a large audience pool. Choosing a narrower subcategory such as “Software Development” or “IT Services and IT Consulting” targets a smaller but far more relevant group. For most SMEs, relevance beats reach. A small audience of decision-makers in your actual sector converts better than a large audience of loosely related professionals.

The trade-off shows up clearly in advertising. Broad categories produce cheaper impressions and lower conversion rates. Niche categories produce fewer impressions and generate leads from people who already understand what you do.

Industry Selection and LinkedIn SEO

LinkedIn’s internal search indexes company pages in much the way Google indexes websites, and the industry field carries keyword weight within that index. A digital marketing agency categorised under “Advertising Services” ranks differently in LinkedIn search than one categorised under “Marketing Services”, even where both descriptions fairly reflect the business.

Checking your page visitor demographics will show whether the current selection attracts the right roles and sectors. If visitors come predominantly from industries unrelated to your target clients, the category may be the cause. ProfileTree’s social media team includes LinkedIn page audits in organic channel reviews, and misaligned industry settings come up repeatedly as a quick-win fix.

The LinkedIn Industry Master List: Categories and Subcategories

LinkedIn organises industries into parent categories with subcategories beneath each. The tables below cover the groupings most used by UK and Irish businesses, with the subcategories most relevant to SMEs in each sector. Labels are reproduced as LinkedIn spells them, in American English, because that is what appears in the dropdown.

Technology and Software

This cluster covers businesses that build, sell, or support technology products and services. It is one of the most populated groups on LinkedIn and the one where subcategory precision matters most, since recruiters and buyers use narrow filters to separate software vendors from IT support firms.

Financial Services

The financial services group spans a wide range of regulated and non-regulated activities. UK businesses here should pay attention to FCA-relevant distinctions: a firm regulated for investment advice sits in a different category to one selling accountancy software, even where both describe themselves as fintech.

Note the full label on the last row. LinkedIn lists it as “Venture Capital and Private Equity Principals”, and searching the dropdown for “private equity” alone will still surface it.

Professional Services

Professional services cover a broad range of knowledge-based businesses. For agencies and consultancies in the UK and Ireland, this group contains several options that are easily confused. The distinction between “Business Consulting and Services” and “Management Consulting” is meaningful because recruiters and buyers use them as separate filters.

Manufacturing, Retail and Other Sectors

Beyond technology and professional services, LinkedIn covers the full economic spectrum. The entries below capture the categories most used by SMEs in Northern Ireland and the Republic of Ireland, where manufacturing, food production, hospitality, and construction make up a significant share of the business base.

One trap worth flagging on that list. “Health and Human Services” sounds like the natural home for a care provider, but in LinkedIn’s taxonomy, it sits under Government Administration and covers public bodies administering human resource programmes. Private care providers and clinics belong under “Hospitals and Health Care”.

Mapping LinkedIn Industries to UK SIC and Irish NACE Codes

The persistent problem for UK and Irish businesses is that LinkedIn’s taxonomy is built on the North American Industry Classification System. Microsoft publishes a dedicated NAICS mapping table alongside the main reference, and states plainly that LinkedIn’s own industry IDs are different from the NAICS-defined codes. Neither system maps cleanly onto UK SIC 2007 or Irish NACE Rev. 2.

This is worth stating precisely, because a lot of published guidance describes LinkedIn’s list as SIC-based. It is not. UK SIC and NAICS are separate classification systems with different structures, and the practical effect is that any SIC-to-LinkedIn mapping is an approximation rather than a lookup.

Why the US and UK Terminology Gap Matters

The clearest example is defence. LinkedIn lists the category as “Defence and Space Manufacturing”, using the American spelling. A UK aerospace and defence contractor searching the dropdown for “defence” will find nothing. Equally, “Staffing and Recruiting” is the LinkedIn term, while most UK businesses would search for “recruitment” or “employment agency”.

The fix is to search the dropdown using American spellings and root words rather than full British terms. The search is string-based, so typing “optimiz” will surface entries containing “optimisation” while “optimis” returns nothing. Searching a short root such as “recruit”, “defen”, or “market” avoids the problem entirely.

Common UK SIC to LinkedIn Industry Mappings

The table below gives practical guidance for UK businesses working from their Companies House SIC code. Irish businesses registered with the CRO under NACE Rev. 2 can use the same mapping, since NACE and UK SIC 2007 align closely at the two-digit level.

Alignment in that final column is a judgment about how closely the two definitions overlap, not an official mapping. Where it reads Medium, expect the LinkedIn category to cover a broader or narrower set of activities than the SIC code does.

How to Handle a Poor Fit

When no LinkedIn industry maps cleanly to your SIC code, prioritise where your buyers and target recruits look rather than what your statutory filing says. A business registered under SIC 74909, “other professional, scientific and technical activities not elsewhere classified”, is usually better served by “Business Consulting and Services” on LinkedIn, even though the statutory code is a catch-all. The goal is visibility to the right audience, not taxonomic accuracy.

Two further options exist when the fit is genuinely poor. Use the Specialities field on the company page to name the activities the category misses. And check the subcategory level rather than stopping at the parent, since the V2 hierarchy runs several levels deep and the useful entry is often two or three levels down from the obvious one.

For businesses serving clients across multiple sectors, such as a content marketing agency working with both FMCG brands and financial services firms, the choice usually comes down to where the majority of revenue originates or where the business wants to grow.

The Hybrid Industry Problem: When One Category Is Not Enough

A company page can select only one industry. That creates an immediate difficulty for businesses genuinely operating across more than one sector. A fintech company is both a software business and a financial services business. A firm building renewable energy infrastructure spans “Environmental Services” and “Renewable Energy Semiconductor Manufacturing”. A digital agency delivering web design, search engine optimisation, and AI transformation could plausibly sit across three or four categories.

The Strategic Choice: Where Are Your Buyers?

The most practical way to resolve this is to ask one question: which industry category are the people who buy from you most likely to have set on their own LinkedIn pages? Your selection does not need to describe what you do. It needs to reflect the professional context in which your ideal clients will come across you.

A law firm using LinkedIn to attract commercial clients should consider “Legal Services”. The same firm using LinkedIn mainly to recruit junior solicitors might get better traction under “Law Practice”. These are separate categories with different audience pools, and the right answer depends on the primary objective for the channel.

“The industry field is one of the lowest-effort, highest-impact changes a business can make to its LinkedIn presence,” says Ciaran Connolly, founder of ProfileTree. “We see it consistently when auditing client pages: the company is broadly visible but attracting the wrong audience. Switching to a more specific subcategory can change the composition of your page visitors within a few weeks.”

Broad Versus Niche: The Trade-off in Practice

Choosing “Technology, Information and Internet” places a company in a pool of several million pages globally. Choosing “Software Development” narrows that to a much smaller set. For advertising, narrower targeting typically produces a higher cost per thousand impressions and a meaningfully lower cost per qualified lead.

For organic visibility, the niche advantage is clearer still. When a recruiter or procurement manager filters search results by industry, they rarely pick a broad parent category. They select the specific subcategory relevant to their search, and a company sitting in the parent will not appear in those results.

Businesses building a B2B pipeline through LinkedIn should also consider how the selection fits their wider digital strategy. LinkedIn works best as one component of a joined-up approach covering content, paid campaigns, and a well-structured company page.

The Primary Revenue Rule

Where a business genuinely cannot decide between two viable categories, the simplest tie-breaker is primary revenue. Select the industry reflecting where the majority of turnover comes from today. Review it annually. LinkedIn allows the field to change at any time with no penalty to page authority or follower count.

Choosing an Industry as a Student, Graduate or Career Changer

Pick the industry you want to work in, not the one you are technically in today. This is the single most common mistake on personal profiles, and it costs people recruiter visibility at exactly the point they need it most.

The reasoning is straightforward. Recruiters filter candidate searches by industry to build a shortlist. That filter reads your profile setting, not your ambitions, your degree subject, or your cover letter. A graduate who wants to work in software but has their industry set to retail because of a part-time job will not appear in a filtered search for software candidates.

The Higher Education Trap

Students very often select “Higher Education” because they are at university. In LinkedIn’s taxonomy, “Higher Education” describes entities that grant degrees. Setting it signals that you work for a university, which puts you in front of recruiters hiring lecturers and administrators rather than the graduate schemes you are applying to.

LinkedIn will suggest an industry based on your current role and company. Treat the suggestion as a starting point and override it where it points at the wrong sector.

Career Changers and the Transition Period

The same logic applies to anyone moving sectors, with one qualification. If you are still employed in your current field and your search is confidential, switching your profile industry is a visible change that colleagues may notice. Where discretion matters, update the industry once your search is public, and use your headline and About section to signal direction in the meantime.

Leaving the field blank is the worst option available. An empty industry means you drop out of every industry-filtered search rather than appearing in the wrong one.

How to Change Your LinkedIn Industry: Desktop and Mobile

Changing the industry on a company page takes a couple of minutes, though the path differs between desktop and the mobile app. This is one of the more commonly unanswered questions about company page management, particularly for teams working from mobile devices.

Changing Industry on Desktop

Go to your company page and click “Edit page” in the top right of the page header. Select “Page info” from the left-hand menu. The industry field sits under “Company details”. Click it to open the dropdown search, type your chosen industry name or a relevant root word, select from the results, and save. Changes take effect immediately, though LinkedIn’s index may take a day or two to reflect the update in search.

Changing Industry on Mobile

The mobile path is less obvious. Open the app and go to your company page, tap the pencil or edit icon near the top, and scroll to the “Company details” section. Tap “Industry” to open the search field, enter your preferred term, select from the dropdown, and save.

Changing Industry on a Personal Profile

For individual profiles, the industry field is set separately from the company page. Go to your profile, click the pencil icon on the intro section, and scroll to “Industry”. Personal profile industries do not need to match the company page exactly, though alignment generally helps with consistent visibility in recruiter searches.

Businesses managing LinkedIn as part of a wider social programme usually get more from a full page audit than from changing settings in isolation. ProfileTree’s social media marketing team reviews company page settings, content strategy, and paid campaign targeting together for SMEs across Northern Ireland and the UK.

Building a Content Strategy Around Your LinkedIn Industry

Getting the category right is the foundation. Sustained visibility needs a posting strategy that reinforces the category signal with relevant, consistent content. LinkedIn weighs engagement from people within the same industry more heavily than engagement from outside it, which means content landing well in your sector compounds the benefit of correct categorisation.

Content Formats That Perform in Each Industry

Industry norms vary. Technology and marketing businesses see strong engagement from original data, product updates, and opinion pieces. Professional services firms typically do better with case study content and commentary on regulatory or market developments. Construction and manufacturing businesses often find that project photography and behind-the-scenes material outperform text-heavy posts.

Across all sectors, native LinkedIn posts tend to reach further than posts built around an external link, because the algorithm favours content that keeps users on the platform. Short posts under 150 words asking a direct question also tend to beat longer posts on engagement rate, even where they generate fewer impressions overall.

Aligning Employee Profiles With the Company Page

LinkedIn aggregates signals from employee profiles as well as company pages. Where several employees have industry settings matching the company page, the platform treats the company as a stronger signal for that sector. Getting key team members to align their personal settings is a low-effort action that strengthens collective visibility.

For businesses with a sales function, profile optimisation for individual team members often matters as much as the company page. B2B buyers in the UK increasingly use LinkedIn to vet potential partners before making contact, and a well-built individual profile becomes a real commercial asset. ProfileTree’s digital marketing services cover LinkedIn profile strategy as part of broader B2B campaign work.

Using Analytics to Validate Your Selection

After changing the setting, monitor the visitor analytics section of your company page for four to six weeks. Look at the job function and industry breakdowns of your page visitors. If the distribution shifts toward your target sectors, the change is working. If visitor industries stay outside your target market, the issue probably sits with content rather than category, and the posting strategy is worth reviewing.

Follower demographics give a longer-term view of whether the overall presence attracts the right professional audience. This data is available to page administrators under the Analytics tab and needs no Premium or Sales Navigator subscription. The same principle of checking free platform data before paying for tooling applies across channels, and the guide to free Twitter analytics sets out which native and third-party options still work on X.

Where to Start

The industry field carries more algorithmic weight than most businesses realise, and fixing it costs nothing. Check your current selection against the mappings above, search the dropdown using American spellings and short root words, and pick the category your buyers and target recruits filter by, rather than the one matching your Companies House filing.

Then check your visitor analytics four to six weeks later. If the mix of visiting industries has moved toward your target sectors, the change worked. If it has not, the problem is the content rather than the category.
