Best industrial SEO companies and industrial SEO services compared, and the specification a procurement engineer now asks ChatGPT for

Industrial SEO is a different job from ordinary business to business SEO because of what the buyer types. An engineer or a procurement officer searches a part number, a material grade, a standard, a tolerance or a failure symptom. They do not search for thought leadership. So the work is almost entirely about getting product and application data onto crawlable pages in a form a technical buyer can use, and the agency that can do it is the one whose writers can read a drawing.

This page is about the SEO purchase specifically. The wider question of which agency should run all of your marketing is answered by two live comparisons on this site, the specification question that sorts industrial marketing agencies and the one capability that eliminates most of a manufacturing shortlist, and this page deliberately does not restate either.

The five page types that carry industrial search

• The part or SKU page. One page per part, with the part number in the title and in text rather than only in a drawing or a PDF table. This is the highest value and most neglected asset in the category.
• The specification table in HTML. Dimensions, materials, tolerances, ratings and compliance marks as text. A specification that exists only inside a PDF or an image is invisible to the thing doing the searching.
• The application page. What the part is used for, in the buyer own words: the industry, the duty, the failure mode it solves. This is where the problem symptom searches land.
• The standards page. Pages organised around the standard or specification number a buyer is required to meet, stating what you supply against it.
• The request for quote page. The conversion page for the whole site. Short, specific to the product family, and asking for the information your estimating team actually needs.

The two problems that are specific to this category

The directory owns the query. The industrial sourcing directories rank hard for generic supplier searches, which means your own site competes with a listing that may describe you from old data. Thomas, the oldest of them, is now a Xometry property; xometry.com carries an article headlined "How Thomas Is Quietly Powering America Manufacturing Revival", read on 21 October 2026, while thomasnet.com itself answered our fetch with HTTP 403 and a message asking us to enable JavaScript. That 403 is a record of what the server did on that date and says nothing about the directory value. The practical point stands either way: part of your search presence is a third party record, and somebody has to own keeping it correct.

Your distributors compete with you. If you sell through distribution, your distributors are optimising for the same part numbers, often with your own copy. Decide the policy before the campaign: whether you rank for the part and refer the enquiry, or cede the transactional query and own the application and specification searches. An agency that starts work without settling this will spend your money bidding against your own channel.

Ranked on one criterion, applied to everybody including us

Rank the suppliers on one thing you can test before signing: send one product and ask for a 300 word application page, then have your own engineer read it for technical error. It costs a day, it applies to every supplier equally, and it eliminates most of a shortlist.

The industrial specialist agency ranks first on that test, because a firm that has written for machine shops and valve makers has subject matter editing built into its process. The technical content agency with no industrial record ranks second and sometimes passes the test outright, which is worth knowing because its rate is usually lower. The general SEO agency ranks third: it will get the site structure right and produce copy your engineer rejects. The freelance technical writer plus an in house marketer ranks fourth on breadth and often first on accuracy, and is the honest answer for a single product line.

What to settle before the engagement starts

• Data access. Where the product data lives, who exports it, and in what format. Most industrial SEO projects stall here rather than on strategy.
• Technical review. One named engineer who reads copy before publication, with an agreed turnaround. Without it, publishing gets blocked or wrong pages go live.
• Whether datasheets are gated. A gated datasheet is a lead form and an uncrawlable page. Decide per document rather than as a blanket policy.
• The distributor policy, in writing. Which queries you pursue and which you leave to the channel.
• The measure. Request for quote submissions by product family, and quoted value, not sessions. Industrial cycles are long, so agree the leading indicator as well as the lagging one.

Questions manufacturers ask about industrial SEO

Do we need pages for every part number?

For every part a customer searches by number, yes, and that is usually a subset rather than the whole catalogue. Start with the families that carry revenue and the ones your inside sales team gets asked about most, because those are the same list.

Should our specifications be public?

Publish the specification and keep the price conversation. A buyer who cannot confirm the spec will not enquire, so hiding it loses the enquiry you were trying to capture. Where a figure is genuinely commercially sensitive, publish the range and the method of confirming it.

When can industrial SEO be judged in orders?

Read part and specification pages in Search Console impressions for part numbers and specifications once the data goes up properly; how far they move depends on competition, your offer and your budget. Orders follow the buying cycle, which in capital equipment and tooling is measured in quarters rather than weeks, so judge the first six months on enquiry quality and the year on revenue.

What about trade shows and the directories?

Both still produce enquiries and neither replaces owning your own pages. Treat the directory listing as a record to be kept accurate and the show as a source of the application questions your pages should answer.

Is our website really the first thing a buyer sees?

Increasingly it is the second. The first is an answer assembled by something else, built from your pages, a directory entry and a competitor comparison, which is the next section.

What an assistant tells an engineer who asks who supplies this

The sourcing question has moved. An engineer with a specification now asks an assistant who supplies a part to that spec, and gets back a handful of named suppliers assembled from manufacturer pages, directory records and distributor catalogues. A manufacturer whose specifications live inside PDFs is not in that answer, and a manufacturer whose directory record is five years out of date is in it inaccurately. AI Knows Us puts that sourcing question to ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews on a schedule you set, then reports which supplier each one came back with and the page it was reading when it did, so you can tell whether the gap is your own data or somebody else record of you. It is not an SEO agency and it writes no part pages. A rival is ahead of us on enterprise requirements: Profound publishes "SSO/SAML + SOC 2 compliance" on its Enterprise tier at tryprofound.com/pricing, read 21 October 2026, and our own pricing page, read the same day, carries no such line.
