LinkedIn Industries: How to Choose the Right Category

Picking a LinkedIn industry feels like a minor admin task. In practice, it determines whether recruiters, potential clients, and B2B buyers find your company page when they search. Get it wrong, and you disappear into the wrong algorithm bucket. Get it right and your page surfaces for exactly the audiences you need.

LinkedIn now uses more than 400 industry categories, including granular subcategories that go well beyond broad labels like “Technology” or “Finance.” For UK and Irish businesses, there is an added layer of complexity: LinkedIn’s taxonomy is built around US Standard Industrial Classification conventions, which do not always map cleanly to UK SIC codes or Irish NACE classifications.

This guide on LinkedIn industries covers every major category, explains how to handle the hybrid industry problem, and shows you how to build a LinkedIn presence that connects your category selection to a wider digital strategy.

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 when a buyer uses LinkedIn’s company search to find potential partners, the industry tag is one of the first filters applied. Pages outside the expected category simply do not appear in those filtered results.

How LinkedIn Uses Industry Data Algorithmically

LinkedIn’s algorithm uses your industry selection for 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 LinkedIn’s advertising platform, which lets advertisers target audiences by industry with significant precision. Third, it shapes your LinkedIn Feed, influencing which posts, articles, and company updates your followers see from others in the same category.

For B2B businesses in Northern Ireland and the UK, this third function is particularly relevant. If your page sits in the wrong category, your content is shown to audiences with no commercial interest in what you sell. The result is low engagement, poor follower growth, and weak performance on paid campaigns.

The Difference Between Reach and Relevance

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

This trade-off matters when running LinkedIn advertising campaigns. Broad categories produce cheaper impressions but lower conversion rates. Niche categories produce fewer impressions but generate leads from people who already understand what you do.

Industry Selection and LinkedIn SEO

LinkedIn’s internal search engine indexes company pages much like Google indexes websites. The industry field carries keyword weight within that index. A digital marketing agency categorised under “Advertising Services” will rank differently in LinkedIn search than one categorised under “Marketing Services,” even if both descriptions accurately reflect what the business does.

Checking your LinkedIn analytics for page visitor demographics can reveal whether your current industry selection is attracting the right roles and sectors. If your visitors are predominantly from industries unrelated to your target clients, the category may be the cause. ProfileTree’s social media marketing services include LinkedIn page audits as part of organic channel reviews, which regularly flag misaligned industry settings as a quick-win fix.

The LinkedIn Industry Master List: Categories and Subcategories

LinkedIn organises its industries into parent categories with subcategories beneath each. The table below covers the main groupings used by UK and Irish businesses, with the subcategories most commonly relevant to SMEs in each sector. This reflects LinkedIn’s 2026 taxonomy.

Technology and Software

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

Financial Services

The financial services cluster spans a wide range of regulated and non-regulated activities. UK businesses in this sector should pay attention to FCA-relevant distinctions: a firm regulated for investment advice sits in a different category to one offering accountancy software, even if both describe themselves as “fintech.”

Professional Services

Professional services cover a broad range of knowledge-based businesses. For agencies and consultancies in the UK and Ireland, this cluster contains several options that are easily confused. The distinction between “Business Consulting and Services” and “Management Consulting” is meaningful on LinkedIn: 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 commonly used by SMEs in Northern Ireland and the Republic of Ireland, where manufacturing, food production, hospitality, and construction represent significant portions of the business base.

Northern Ireland has a diverse SME economy that spans several of these categories simultaneously. Businesses looking to position themselves for visibility across the UK and Irish markets may find useful context in this guide to Northern Ireland’s key cities and business hubs, which highlights the regional economic spread that shapes digital marketing decisions for local businesses.

Mapping LinkedIn Industries to UK SIC and Irish NACE Codes

One of the most persistent problems for UK and Irish businesses is that LinkedIn’s industry taxonomy was built around US Standard Industrial Classification codes. The naming conventions are American, the categories reflect a US economic structure, and several common UK business types do not have a clean, direct equivalent.

Why the US/UK Terminology Gap Matters

The clearest example is the word “Defence.” LinkedIn lists the category as “Defence and Space Manufacturing,” using American spelling. A UK aerospace and defence contractor searching for the right category may look for “Defence” and fail to find it. Similarly, “Staffing and Recruiting” is the LinkedIn term, whereas most UK businesses would search for “Recruitment” or “Employment Agency.”

The practical fix is to use both British and American spellings in LinkedIn’s dropdown when setting up or reviewing your company page. The platform’s search is string-based, so entering “optim” will surface categories containing “optimisation” but not “optimisation” unless the term is in the full category name.

Common UK SIC to LinkedIn Industry Mappings

The table below provides practical guidance for UK businesses working from their Companies House SIC code. Irish businesses registered with the CRO under NACE Rev. 2 codes can use the same mapping, as NACE and UK SIC 2007 are largely aligned at the two-digit level.

How to Handle a Poor Fit

When no LinkedIn industry maps cleanly to your UK SIC code, the right approach is to 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”) may be best 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.

For businesses that serve clients across multiple sectors, such as a content marketing agency working with both FMCG brands and financial services firms, the choice often 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

LinkedIn allows a company page to select only one industry. This creates an immediate difficulty for businesses that genuinely operate across more than one sector. A FinTech company is both a software business and a financial services business. A GreenTech firm building renewable energy infrastructure spans “Environmental Services” and “Renewable Energy Semiconductor Manufacturing.” A digital agency like ProfileTree, which delivers 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 framework for resolving the hybrid problem is to ask a single question: in which industry category are the people who buy from you most likely to have their own LinkedIn pages set to? Your industry selection does not need to reflect what you do. It needs to reflect the professional context in which your ideal clients will encounter you.

A law firm using LinkedIn to attract commercial clients should consider “Legal Services.” The same law firm using LinkedIn primarily to recruit junior solicitors might get better traction under “Law Practice.” These are different categories with different audience pools, and the right answer depends on the primary business objective for the LinkedIn 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 vs. Niche: The Algorithmic Trade-off in Practice

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

For organic visibility on LinkedIn, the niche category advantage is clearer. 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. A company in the broad parent category will not appear in those filtered results at all.

Businesses that want to build a B2B pipeline through LinkedIn should also consider how their industry selection aligns with their digital strategy more broadly. LinkedIn works best as one component of a joined-up approach that includes 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 that reflects where the majority of turnover comes from today. This can be reviewed annually, and LinkedIn allows you to change the industry field at any time with no penalty to page authority or follower count.

How to Change Your LinkedIn Industry: Desktop and Mobile

Changing the industry on a LinkedIn Company Page takes only 2 minutes, but the specific path differs between desktop and the mobile app. This is one of the most commonly unanswered questions about LinkedIn company page management, particularly for teams that manage pages from mobile devices.

Changing Industry on Desktop

On desktop, go to your Company Page and click the “Edit page” button in the top right of the page header. Select “Page info” from the left-hand menu. The “Industry” field is visible under the “Company details” section. Click the field to open the dropdown search. Type your chosen industry name or a relevant keyword. Select from the results and save. Changes take effect immediately, though LinkedIn’s index may take 24 to 48 hours to reflect the update in search.

Changing Industry on Mobile (iOS and Android)

The mobile path is less intuitive. Open the LinkedIn app and go to your Company Page. Tap your company logo or the “Me” icon and select your page from the list. Tap the pencil/edit icon near the top of the page. Scroll to the “Company details” section. Tap “Industry” to open the search field. Enter your preferred term and select from the dropdown. Tap “Save” to confirm. The mobile UI was updated in early 2026, and the edit option is now accessible without switching to desktop mode.

Changing Industry on a Personal Profile

For individual employee 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.” LinkedIn will suggest options based on your current role and company, but you can override these. Personal profile industries do not need to match the company page exactly, but alignment generally helps with consistent visibility in recruiter searches.

Businesses managing LinkedIn as part of a wider social media programme may find it useful to conduct a full-page audit rather than changing settings in isolation. ProfileTree’s social media marketing team works with SMEs across Northern Ireland and the UK to review company page settings, content strategy, and paid campaign targeting as an integrated package.

Building a Content Strategy Around Your LinkedIn Industry

Selecting the right industry category is the foundation. Sustained LinkedIn visibility for B2B businesses requires a posting strategy that reinforces the category signal with relevant, consistent content. LinkedIn’s algorithm weights engagement from people within the same industry more heavily than engagement from outside it, which means content that resonates with your sector compounds the benefit of correct categorisation.

Content Formats That Perform in Each Industry

Industry norms on LinkedIn vary. Technology and marketing businesses see strong engagement from original data, product updates, and opinion pieces. Professional services firms typically perform 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 content outperform text-heavy posts.

Across all sectors, native LinkedIn articles tend to perform better than external links in terms of organic reach, because LinkedIn’s algorithm favours content that keeps users on the platform. Short-form posts under 150 words that ask a direct question also consistently outperform longer posts for engagement rate, even if they generate fewer impressions overall.

Aligning Employee Profiles with the Company Page

LinkedIn aggregates signals from employee profiles as well as company pages. When multiple employees within a business have consistent industry settings that match the company page, LinkedIn’s systems treat the company as a stronger signal for that sector. Encouraging key team members to align their personal profile and industry settings is a low-effort action that strengthens the collective visibility of the business.

For businesses with a sales or business development function, LinkedIn profile optimisation for individual team members is often as important as the company page itself. B2B buyers in the UK increasingly use LinkedIn to vet potential partners before making contact, and a well-optimised individual profile can be a significant commercial asset. ProfileTree’s digital marketing services cover LinkedIn profile strategy as part of broader B2B campaign work.

Using LinkedIn Analytics to Validate Your Industry Selection

After changing your industry setting, monitor the “Visitor analytics” section of your Company Page for four to six weeks. Look specifically at the “Job function” and “Industry” breakdowns of your page visitors. If the industry distribution shifts toward your target sectors, the change is working. If visitor industries remain predominantly outside your target market, the issue may sit with content rather than category, and a review of your posting strategy is worth undertaking.

LinkedIn’s analytics also surface data on follower demographics, which provides a longer-term view of whether your overall presence is attracting the right professional audience. This data is available to page administrators under the “Analytics” tab and does not require a Sales Navigator or Premium subscription to access.

Conclusion

LinkedIn’s industry field carries more algorithmic weight than most businesses realise. Choosing the right category, navigating the gap between US-centric taxonomy and UK SIC codes, and resolving the hybrid industry problem are practical decisions with measurable impact on visibility, recruiter reach, and advertising efficiency. Review your current selection against the mappings in this guide, check your visitor analytics, and treat the industry field as part of your broader LinkedIn strategy rather than a one-time setup choice.
