The Small Business Owner's Glossary of SEO Terms
Quick answer: SEO has its own vocabulary, and most of it exists to describe simple ideas in complicated ways. This glossary defines the terms small business owners actually run into — from "domain authority" to "crawl budget" — in plain English, with no filler and no jargon explaining jargon. Use it as a lookup: find the term, read one or two sentences, move on.
Key takeaways
- Most SEO jargon describes a handful of core ideas: how easily Google can find your pages, how relevant they are to a search, and how much other sites and users seem to trust them.
- Terms like "domain authority" and "spam score" are metrics invented by SEO tool companies, not by Google — Google has never confirmed using them, according to Google's own Search Central documentation.
- A handful of terms — keyword, backlink, meta description, index — cover most of what a small business owner needs to make sense of an SEO report or proposal.
- Understanding the terms doesn't require becoming an SEO expert; it mainly helps you tell the difference between a real recommendation and a sales pitch dressed up in acronyms.
The Core Terms Every Owner Should Know
These are the words that show up in nearly every SEO conversation, report, or tool. If you only learn ten terms, learn these.
- SEO (Search Engine Optimization): the practice of improving a website so it shows up higher in search results for relevant terms, without paying for ads.
- Keyword: a word or phrase a person types into a search engine, like "plumber near me" or "best coffee shop in Tulsa." Businesses target keywords by writing content that answers what the searcher wants.
- SERP (Search Engine Results Page): the page of results you see after searching. SEO work is aimed at getting your business to appear higher on this page.
- Organic traffic: visitors who land on your site from unpaid search results, as opposed to visitors from ads, social media, or direct links.
- Index / Indexing: when Google scans a page and adds it to its massive database of known web pages. A page that isn't indexed can't show up in search results at all, no matter how good it is.
- Crawl: the process by which Google's automated programs ("crawlers" or "bots") visit and read pages across the web to decide what they're about.
- Meta description: the short snippet of text under your page's title in search results. It doesn't directly boost rankings, but a clear, honest one affects whether people click.
- Title tag: the clickable headline shown in search results for a page. It's technically separate from the page's visible headline, though most website builders set them to match by default.
- Backlink: a link from another website pointing to yours. Backlinks act like word-of-mouth referrals in Google's eyes — more credible sites linking to you signals trustworthiness.
- Domain: your website's address, like segeo.net. A domain's age and history can factor into how search engines view it.
What Do "Domain Authority" and Similar Scores Actually Mean?
Domain authority is a third-party metric estimating how likely a website is to rank well, based on its backlinks and overall profile — but it is not a Google metric. It was created by the SEO software company Moz, and other tools publish their own similar scores under different names, such as "domain rating" or "authority score." These numbers can be useful for comparing your site to a competitor's over time, but no search engine has confirmed using them to decide rankings, per Google's own how search works documentation.
This distinction matters because it's an easy way to spot an inflated pitch. If someone promises to raise your "domain authority" as if that guarantees more traffic or sales, treat it as one input among many, not a scoreboard.
Related metrics you'll see in tools and reports:
- Spam score: a tool's estimate of how likely a site is to be penalized or ignored, based on patterns common in low-quality or manipulative sites.
- Page authority: the same idea as domain authority, but scored for a single page instead of the whole site.
- Trust flow / citation flow: metrics from the tool Majestic, measuring link quality and link quantity separately.
Don't skip this: Any metric with "authority," "trust," or "score" in the name is almost certainly a third-party estimate, not a number Google publishes or confirms. Treat these as directional signals, not proof of ranking power.
Local SEO Terms Explained
Local SEO is the set of practices that help a business show up in searches tied to a location, like "electrician in Reno" or searches near the user's current position. It runs on a mostly separate set of signals from general SEO, which we cover in full in What Is Local SEO? A Plain-English Overview.
Terms specific to this corner of SEO:
- Google Business Profile (formerly Google My Business): the free listing that shows your business hours, reviews, photos, and location in Google Search and Maps. It's often the single highest-impact thing a local business can maintain, a topic we go deeper on in Google Business Profile vs. Website SEO: What Matters More?
- NAP consistency: shorthand for Name, Address, Phone number — meaning these details should match exactly across your website, Google listing, and any directories you appear in.
- Local pack (or "map pack"): the block of three business listings with a map that appears above regular results for local searches.
- Citation: any online mention of your business's name and address, whether or not it links back to your site — think Yelp, Yellow Pages, or industry directories.
- Service area business: a business that serves customers at their location rather than a fixed storefront (plumbers, landscapers, mobile groomers), which changes how Google Business Profile should be set up.
Content and On-Page SEO Terms
On-page SEO refers to everything you control directly on your own website — as opposed to off-page factors like backlinks, which happen elsewhere on the web. This is where most of the day-to-day blogging and content decisions live.
| Term | Plain-English Meaning |
|---|---|
| Content marketing | Publishing useful material (blog posts, guides, videos) to attract and keep an audience, rather than paying to interrupt them with ads |
| Search intent | What a searcher actually wants when they type a query — informational, navigational, or ready-to-buy |
| E-E-A-T | Google's shorthand for Experience, Expertise, Authoritativeness, and Trustworthiness — qualities its quality raters are trained to look for in content, per Google's Search Quality Rater Guidelines |
| Thin content | Pages with little original value — too short, duplicated, or auto-generated without substance |
| Internal linking | Linking from one page on your site to another, helping both users and search engines navigate and understand your content |
| Alt text | A short written description of an image, read by screen readers and search engines since they can't "see" pictures |
| Canonical tag | A code snippet telling search engines which version of a page is the "main" one when duplicates exist |
| Schema markup | Extra code added to a page that helps search engines understand specific details, like a recipe's cook time or a business's star rating |

Technical SEO Terms That Actually Matter for Small Sites
Technical SEO covers the behind-the-scenes settings that affect whether search engines can crawl, understand, and trust your site — most of which a small business owner will never touch directly, but should recognize when a developer or SEO vendor mentions them.
- Crawl budget: the limited number of pages Google's bots will crawl on your site in a given period. This mostly matters for very large sites; a small business site rarely needs to worry about it.
- XML sitemap: a file listing every important page on your site, submitted to help search engines find them faster.
- Robots.txt: a file that tells search engine bots which parts of your site they're allowed or not allowed to crawl.
- Core Web Vitals: a set of measurements Google uses to judge page experience — how fast a page loads, how quickly it becomes usable, and how much its layout shifts while loading, according to Google's Core Web Vitals documentation.
- HTTPS: the secure version of a website connection, shown as a padlock icon in the browser bar. Google has confirmed HTTPS is a ranking signal, though a minor one on its own.
- 404 error: the "page not found" error shown when a link points to a page that no longer exists or never did.
- Redirect (301): an instruction that permanently sends visitors and search engines from an old URL to a new one, commonly used when a page is renamed or removed.
- Mobile-first indexing: Google's practice of primarily using the mobile version of a site's content to determine rankings, even for searches made on desktop, per Google's own announcement.
Reporting and Measurement Terms You'll See in Any SEO Proposal
Analytics terms are where a lot of confusion — and a lot of vague reporting — happens, because several of these words sound like they measure success when they mostly measure activity.
- Bounce rate: the percentage of visitors who leave after viewing only one page. A high bounce rate isn't automatically bad; someone who reads a blog post, gets their answer, and leaves satisfied still counts as a bounce.
- Conversion rate: the percentage of visitors who complete a desired action — booking a call, making a purchase, filling out a form.
- Click-through rate (CTR): the percentage of people who see your listing in search results and actually click it.
- Impressions: the number of times your page showed up in search results, whether or not anyone clicked.
- Ranking / Position: where your page lands on the results page for a specific search term, typically tracked as a number (position 1, position 5, and so on).
- ROI (Return on Investment): what you got back compared to what you spent — the number that matters most, and the one vaguest reports tend to avoid.
If a report leans heavily on impressions and rankings but never mentions leads, calls, or sales, that's worth a direct question.

A Quick Checklist for Reading Any SEO Report or Proposal
Before signing off on an SEO plan or reading through a monthly report, run it against this list:
- Confirm which numbers are Google's own metrics (clicks, impressions, position) versus a third-party tool's estimate (domain authority, spam score).
- Ask what search intent the content targets — informational searches convert differently than "ready to buy" searches.
- Check whether your Google Business Profile is mentioned at all, especially if you serve local customers.
- Look for conversion or lead numbers, not just traffic and ranking numbers.
- Ask which pages are indexed and which aren't, if the site is more than a year or two old.
- Verify NAP consistency across your website, Google listing, and major directories if local SEO is part of the plan.
Getting fluent in these terms is really about being able to tell a substantive recommendation from a padded one — a skill that also pays off when just reviewing your own site's content. We covered the more common ways that content and technical setup go wrong in 7 Common SEO Mistakes Small Businesses Make (and How to Fix Them).
None of this vocabulary is complicated once you strip the sales language out of it. Most of it boils down to three questions: can search engines find your page, does it answer what someone's actually searching for, and do other signals suggest people trust it. If you'd rather skip translating jargon every week and just get content published, Segeo writes and publishes a new blog post to your site daily, built around what your industry is actually discussing — no glossary required on your end.
