SEO, DEFINED PLAINLY
What Is an SEO Company, and What Do SEO Firms Do?
An SEO company helps your business show up when customers search for what you sell. Here is a plain definition, what the work looks like each month and how to tell a good firm from one that just sends reports.

THE DEFINITION
What is an SEO company?
An SEO company is a firm that gets your website found in unpaid search results. SEO stands for search engine optimization. The company’s job is to make your site the best, clearest answer to the questions your customers type into Google, Bing and now AI engines like ChatGPT and Gemini.
That is different from advertising. Ads put you at the top of the page for as long as you pay. SEO earns you a spot in the organic results and the map pack that keeps working after the work is done. We compare the 2 in detail in organic rankings vs. pay per click.
A good SEO company works on 3 things at once: the technical health of your site, the content and structure of your pages, and your reputation across the web. Beth Guide has taught that 3 part model since 2003, and it still holds in the age of AI search.
WHAT THE WORK LOOKS LIKE
What does an SEO company do?
A COMMON MIX UP
Is an SEO company the same as a web designer?
No, and this is where a lot of business owners get burned. A web designer makes the site look good and work on a phone. An SEO company makes sure people can find it. Some firms do both well. Many designers do not do SEO at all, even if their proposal says “SEO friendly.”
Beth recorded a whole series on how to hire a webmaster because she kept seeing the same mistakes. One example: header tags. Designers often use H1 and H2 tags just to make text big and bold. Google reads those tags as a summary of what the page is about. Using them for decoration sends Google the wrong message. Another is navigation built for looks instead of for the way people search. Our guide to hiring a web designer walks through the checklist.
That is why we build websites and do SEO under one roof. We explain why in why your web design company should understand SEO.

CHOOSING ONE
How do you choose an SEO company?
Start with 5 questions. What exactly will you do each month? Who does the work, and are they your employees? How will you report results, and will the report show calls and leads? Do I own my content, my Google Business Profile and my analytics? What happens if I leave?
Then test them. Search for the service they sell in their own city. An SEO company that cannot rank for its own services should explain why. Ask them to look at your site and name 3 specific problems. A good firm will find real ones in a few minutes. You can also run our free SEO audit tool first, so you know what to ask about.
Our article on how to choose an SEO company goes deeper, and what SEO services should include gives you a checklist to compare proposals.
HONEST CAVEATS
When should you not hire an SEO company?
Not every business needs one right away. If you are brand new and have no website yet, start with a solid site and a verified Google Business Profile. If you only serve a few large accounts through referrals, SEO may not be where your next customer comes from.
And if a previous firm left your site in worse shape, the first step may be cleanup, not growth. We see that often enough that we wrote about cleaning up after bad SEO and web design firms.

Sorting out the labels
SEO company vs SEO agency vs digital marketing agency: what is the difference?
The labels overlap, and firms use them loosely. An SEO company or SEO agency focuses on search: organic rankings, the map pack and now AI answers. A digital marketing agency usually offers SEO plus other channels, such as PPC, paid media on social platforms, email and content marketing. A web design firm builds the site and may or may not do SEO.
What matters is not the label. It is what the agency actually does each month and who does it. Some agencies sell SEO and send the work to a subcontractor overseas. Some digital marketing agencies are strong at ads and weak at search. Ask to see the work, not the logo list.
We are all three under one roof: SEO, digital marketing and web design, plus hosting. Our team manages more than $1M a year in PPC, writes content, and runs the servers. That mix lets one strategy cover every channel instead of each vendor guarding its own. See the full list on our SEO services page.
The core services
What SEO services does an SEO firm offer? Technical SEO, content strategy and link building
Most SEO firms offer the same core SEO services, even if they name them differently. Here is what each one means and what you should see in the reporting.
- Technical SEO. Speed, crawl errors, indexing, redirects, schema and mobile layout. Our guide on what technical SEO is and why you should care covers it in depth.
- Keyword research and on-page SEO. Finding the search terms buyers use and matching each keyword to one page, with the right title, headings and copy.
- Content strategy. A plan for which pages and posts to write, in what order, based on what the ranking pages cover and what your business knows that they do not.
- Link building. Earning links from real sites, such as chambers, associations, suppliers and local press. No networks and no bought links.
- Local SEO. Google Business Profile, citations, reviews and location pages for every area you serve.
- Reporting. Rankings, traffic, calls and form fills from Search Console and your analytics, explained in plain English.
A full-service SEO agency does all six. If a proposal leaves one out, ask why. Our content marketing page shows how the writing side works.
From rankings to revenue
How an SEO strategy drives growth: visibility, organic traffic, leads and revenue
Rankings are a means, not the goal. A good SEO strategy starts with the business goal, such as more calls, more quote requests or more online sales, and works back to the searches that bring those customers. Visibility for the wrong terms is just traffic that never buys.
The path looks like this. Better pages and a healthier site increase your visibility in search. More visibility brings more organic traffic. Better engagement on the page, meaning a clear offer, fast loading and an obvious next step, turns more of that traffic into leads. Conversion is where revenue shows up, and it is the number we report first.
That is why our reports lead with calls, forms and sales, not a ranking chart. Because we also run paid search, we can show what those organic leads would have cost as ads, which gives you a real way to judge the success of the work. An SEO company should be able to explain its value in your numbers, not its own.
Every market is different
SEO companies by industry: ecommerce, SaaS, healthcare and enterprise SEO
SEO work changes with the industry. Ecommerce SEO is about product and category pages, site structure and speed across thousands of URLs; our ecommerce web design team builds stores with that in mind. SaaS SEO is about explaining a product clearly, comparing it honestly and answering the questions buyers ask before a demo. Healthcare SEO is local and trust-driven, with strict care around claims.
Enterprise SEO is its own market. Large brands need teams that coordinate with developers, legal and many departments, and the agencies that serve them are built for that. Most of our clients are small and mid-size businesses and professional practices, from law firms and dental offices to manufacturers and home services. That experience is where we are strongest, and we will tell you if your project needs something else.
Whatever the industry, ask the SEO company for examples in your market. A firm with real experience will know your competitors, your search terms and the mistakes your industry makes most.
The new search results
What SEO firms do about AI search and GEO
More buyers now ask ChatGPT, Gemini, Perplexity or Google’s AI features before they ever click a result. Some call the work of showing up there GEO, generative engine optimization. It is not a separate trick. The AI engines quote pages that answer questions clearly, that name what the business does and where, and that the rest of the web trusts.
A modern SEO company should track which buyer questions name your business in the AI engines and which name a competitor, then build the pages that change the answer. We run a fixed set of those questions every month for our clients. The method is on our AI SEO services page.
QUESTIONS
SEO company questions we hear
An SEO company is a business that improves how often and how high a client’s website appears in unpaid search results on Google, Bing and AI engines. It does that by fixing the site’s technical health, improving its content and structure, and building the client’s reputation across the web.
Typical weekly work includes keyword research, rewriting title tags and headings, fixing crawl errors and slow pages, writing new content, managing Google Business Profiles and citations, earning links, checking rankings and reporting results to the client.
No. A web design company builds the site and makes it look good. An SEO company makes sure people can find it. Some firms do both well, many do only one. Ask a web designer to explain title tags and header tags before assuming they handle SEO.
Ask what they will do each month, who does the work, how they report results and whether you own your accounts and content. Search for their own services and see whether they rank. A good firm can explain its work in plain English.
Honest ones do not. Nobody controls Google’s algorithm. A reputable firm will set realistic targets, show you its process and report progress against calls and leads, not just rankings.
Yes, for the basics. Many owners learn to write good title tags, set up a Google Business Profile and ask for reviews. Hiring a company makes sense when the competition is stiff, the site has technical problems or your time is better spent running the business.
It depends on how many locations, services and pages need work and how competitive your market is. Our plans are published on the SEO pricing plans page, and a free website audit shows which one fits before you spend anything.
An SEO specialist researches keywords, fixes technical problems, writes or edits content, builds links and reports results. At a full-service agency those jobs are split across a team that includes developers, writers and local SEO staff.
For most local and B2B businesses, yes. Organic traffic and map pack visibility keep bringing leads after the work is done, unlike ads that stop when you stop paying. It is not worth it when a firm cannot explain what it will do each month.
Fixing a broken site or a weak Google Business Profile can show movement quickly. Competitive terms usually take several months of steady work. A good agency shows progress in Search Console and in leads along the way.
Full-service SEO covers technical SEO, keyword research, on-page work, content, link building, local SEO and reporting under one plan, so nothing falls between vendors.
