A lot of the search work bought in this region is not marketing in the way the word is usually meant. The SEO work is making a catalogue findable. The customer already knows what they need, often down to a part number, and the question is whether your site answers before a distributor, a marketplace listing or a competitor's spec page does. That is a different discipline from writing articles, and the proposals you receive will not all understand the difference.
Most SEO briefs in Detroit are really catalogue and specification problems
Manufacturers, tooling suppliers, service shops and the firms that sell into them tend to have the same underlying issue: the valuable information exists, and it is locked in places search engines cannot use. Specifications live inside scanned documents. Dimensions sit in images rather than text. Product families are represented by a single page with a dropdown, so the individual variant a buyer is searching for has no address of its own.
Ask a candidate to open your catalogue in the first meeting and say what is indexable and what is not. That five minute exercise separates SEO firms that have done industrial work from the ones that will hand you a blog calendar. If the answer is that your best material is invisible, the first quarter of the programme writes itself.
Part numbers, cross references and the way engineers actually search
Technical buyers search with strings no keyword tool will ever report: manufacturer codes, legacy part numbers, competitor equivalents, alloy and grade designations, standards references. These queries are rare individually and extremely valuable in aggregate, and they reward a site that gives each item a stable page containing the number in text, the alternatives it replaces, and what it fits.
Cross reference pages are among the highest return SEO assets available in this category and almost nobody builds them properly. Ask how the agency intends to generate them at scale without producing thin duplicates, and how the resulting pages will be linked internally so they are discovered at all. A plan that treats your part data as a database problem rather than a writing problem is thinking correctly.
When a dealer network publishes your words, the words stop working
Firms that sell through distributors, dealers or franchised outlets usually supply them with descriptions, and those descriptions appear verbatim on dozens of other domains, frequently on ones with more authority than yours. You are then competing against your own channel with identical text, and you generally lose.
The fix is editorial and contractual rather than technical. Decide what only you will publish, application guidance, testing results, engineering rationale, service history, and what the channel is free to copy. Ask a prospective SEO supplier how they have handled channel duplication before, because the standard answer, rewriting product descriptions, does nothing if the network receives the rewrite too.
Approval chains determine how much work can actually ship
In regulated and safety sensitive supply chains, published claims pass through engineering and legal, and the queue is slow. An SEO supplier planning a monthly output that assumes instant sign off will spend the retainer producing drafts that sit in review, and the relationship will sour over an issue neither party caused.
Map the approval path before scope is agreed. Who checks technical accuracy, who checks contractual language, how long each step takes in practice rather than in theory. Then size the content commitment to that reality and put the slower, uncontroversial technical SEO work into the same months, so the programme keeps moving when the writing cannot.
Marketplaces and distributors will outrank you for your own products
For many searches involving your brand and a part, the top results are resellers. This is worth measuring deliberately rather than discovering later. Some of it is unavoidable and even useful, because a sale through a distributor is still a sale. Some of it costs you margin and control, and can be reversed by giving the buyer a better destination: complete documentation, availability, compatible items, a way to request a quote without registering.
Ask for a report of brand plus product queries showing who currently occupies the results, and a position on which of those you intend to take back. That single document reframes the conversation from traffic to channel strategy.
Success is a quote request, rarely a session count
Buyers in this sector download a drawing, send a scattered email, call a number from a phone in a plant, or ask a purchasing officer to follow up weeks later. None of that is legible in a standard traffic chart, and SEO reporting built around sessions will show a programme failing while the sales floor gets busier.
Instrument the real events: document downloads by document, quote form completions, tracked calls, and a field in your own system recording how the enquiry arrived. Agree that the measure of the engagement is quote volume and quality from non brand organic search, reviewed on a cycle that matches your sales rhythm rather than the invoice.
Consolidations, migrations and the map you must keep
Many sites here are the result of merged divisions and acquired product lines, and a consolidation is often the trigger for hiring an SEO agency in the first place. The redirect map produced during that work is the single most valuable document the engagement generates and the one most often left in a consultant's spreadsheet. Require it as a deliverable, in editable form, with the crawl exports that justified it.
Hold the rest of the assets too: search console and analytics properties created under accounts your company owns, tag containers in your name, and product data exports kept where your team can reach them. Where the underlying constraint is the platform rather than the content, a team that can run the wider programme or a specialist build partner may need to be involved before search work can pay off.
Turning a Detroit shortlist into a decision
Send three firms the same page: your platform, your catalogue size, who approves technical claims, how orders reach you, and what you have already attempted. Ask each for the first quarter in execution order, the named people and their hours, the approach to variant and cross reference pages, and one thing on your site they would remove. If you would rather write the requirement once and receive replies in a comparable format, describe the work and collect offers. Where earned technical coverage matters as much as rankings, compare the answers against firms that place stories in trade publications, and the overview of SEO agencies explains what the category normally covers.
