Can an SEO company work with any industry?
Yes, in the sense that the methods carry across: making a site crawlable, researching what customers search for, structuring pages, and writing content that answers those searches work the same way for a manufacturer, a dental practice, or a software company. But three kinds of business need more than method, and a company should say so before it starts: fields where Google gives more weight to trust, professions whose advertising is regulated, and technical sectors where a generalist writer can get the substance wrong. For those, ask how the company handles the extra requirements, not only whether it has worked in your industry before.
Where Google expects more
Google’s guidance on creating helpful, reliable, people-first content explains that its systems give more weight to content with strong experience, expertise, authoritativeness, and trust on topics that could significantly affect people’s health, financial stability, or safety, which it calls “Your Money or Your Life” topics. The same guidance notes that content does not have to demonstrate every one of those qualities. For a business in medicine, finance, or law, the sensible editorial safeguards are accurate, sourced information, clear authorship, and, where the subject calls for it, review by a qualified person. A company working in these fields should plan access to your experts from the start.
Professions with advertising rules
Lawyers, doctors, financial advisers, and other licensed professions are bound by rules on how they describe their services, and a website’s content is part of that. The rules differ by profession and by state. Georgia’s rules for lawyers are one example: in the Supreme Court of Georgia’s order amending them, effective March 1, 2026, Rule 7.1 begins: “A lawyer shall not make a false or misleading communication about the lawyer or the lawyer’s services.” Its commentary adds that reporting past results truthfully “may be misleading if presented so as to lead a reasonable person to form an unjustified expectation that the same results could be obtained for other clients in similar matters”. The rule also states: “The maximum penalty for a violation of this rule is disbarment.”
The consequence for SEO work is practical. Case results, testimonials, claims of specialization, and comparisons with competitors cannot be written the way a retailer might write them. The company should ask which rules apply to you, and you should have the content reviewed against them; the responsibility stays with the licensed professional. This is general information, not legal advice; your licensing body’s rules, or a lawyer who advises on them, are the authority for your situation.
Technical sectors
In engineering, manufacturing, scientific equipment, or specialized software, the buyers know the subject and notice errors. The SEO methods are the same, but the content has to be accurate enough for an engineer or specialist buyer to trust. That takes either writers who know the field or close work with your own specialists, and the company should say which it will use.
How a company learns a new industry
A company new to your field should ask for product information, past analytics, and access to the people who talk to customers, so it learns how you win business and what customers ask about. It should study who ranks for your important searches and what those pages offer, learn the vocabulary your buyers use, and, where rules apply, confirm them before writing. Experience in your industry can shorten this, which is a fair reason to prefer a company that has it. Without that experience, ask the company to describe how it will learn your field and who will check its work, and judge the answer on its specifics.
