SEO Terms: The 15 Words Every Lawyer Must Know to Get Started (SEO Basics, Level 0)

The 15 SEO terms every lawyer should know are SEO, SEM, SERP, crawling, indexing, ranking, HTML tags, meta description, keyword, duplicate content, backlink, internal linking, topic cluster, sitemap, and UX. Together, they describe how Google explores, ranks, and displays the pages of your law firm website.

This SEO glossary for beginners starts with the basic trio of SEO, SEM, and SERP. It then explains how Google reads your website through crawling and indexing, and breaks down the practical levers: HTML tags, keywords, backlinks, and user experience. Each term comes with a plain definition and a law firm example.

SEO, SEM, SERP: the three basic SEO terms

1. SEO (search engine optimization)

Many of you wonder why law firms need to invest in SEO. Before we answer that question, let's define the term. SEO is the set of techniques that improve your website's visibility on Google, without paying for ads. You will also hear it called organic search.

Think of it as the sign and the location of your office: the clearer, more readable, more useful, and better placed it is, the more people walking by take an interest.

For example, when someone types "divorce lawyer Houston," the first unpaid results are the websites that rank best for that keyword. They earned their spot naturally, without paying for it.

2. SEM (search engine marketing)

SEM is buying search engine advertising. In the US, you will also hear it called paid search or PPC (pay per click). You pay to appear at the top of the results, and Google marks each ad with a bold "Sponsored" label. That label is how you know a firm paid to be there. Before you start, check the lawyer advertising rules that apply to your firm.

It works like renting a lit billboard above your office: people see it right away, but it disappears the moment you stop paying.

3. SERP (search engine results page)

The SERP is Google's results page. When someone types "business lawyer Chicago," the list of links that appears is the SERP. Your goal: the top spot on the SERP. It is never fixed: Google ranks and reranks the pages on it as it sees fit.

If you run that search today and a colleague runs it next month, you will probably not see the same results. That is completely normal, because the SERP is always changing.

How Google "reads" your website: crawling, indexing, and ranking

Before your page can show up, Google takes it through three steps: it explores the web, stores the pages, then puts them in order. For the full mechanics, read our guide on how Google Search works.

4. Crawling

Crawling is the exploration of your website by Google's robots, called Googlebot. They follow links to discover your pages, so a page that no link points to is hard for them to find.

5. Indexing

Once crawled, a page is indexed if Google decides it deserves a place in its database. Indexing is like being listed in a directory: you exist, and people can find you.

6. Ranking

Ranking is the position of your page among the results. It depends on hundreds of criteria, such as content quality, site speed, and the links your site receives.

What Google sees: HTML tags, content, and keywords

7. HTML tags (H1, H2, and so on)

These are pieces of code that structure your pages. The H1 is the main title, and the H2s are the subsections. Google reads these heading tags to understand the hierarchy of your content.

8. Meta description

The meta description is the short text shown below your page title in Google. It does not count directly toward rankings, but it influences your click-through rate.

In the results, it is the gray text just below the title of each page. Our meta description examples show how to write one that gets clicks.

9. Keyword

A keyword is the phrase you want to show up for, for example "wrongful termination lawyer Los Angeles." Place it naturally in your text. To find the right keywords, with their search volume and relevance, you have several options.

Option 1: use Google. Type a word and look at the searches Google suggests as you type. This feature is called Google Autocomplete, or Google Suggest.

Option 2: use a dedicated tool such as Ubersuggest. Our guide to keyword research for lawyers walks you through the full method.

10. Duplicate content

Duplicate content is, as the name suggests, copy and paste. And Google hates copy and paste. It wants original, useful content written for people.

Credibility and content strategy

11. Backlink

Backlinks are all the websites that talk about you with a link: each one works like a recommendation from another site to yours. The more trusted the site it comes from, the more it strengthens your credibility.

It has the same effect as a referral from a respected colleague. Powerful social proof.

12. Internal linking

Internal linking means the links you place between the pages of your own website. They help Google navigate and understand your structure.

It is like cross-referencing your client files: a smooth organization makes the work flow better.

13. Topic cluster

A topic cluster is a content strategy where pages about the same subject are linked together to build consistency. For example, an employment law parent page links to child pages on wrongful termination, employment contracts, and severance agreements, and those pages link back to it and to each other.

14. Sitemap

A sitemap is a file that lists all the pages of your website to help Google find them faster.

15. UX (user experience)

UX is the quality of your visitor's journey: site speed, readability, and ease of use. Google takes it into account in its rankings.

The bottom line: you already speak SEO without knowing it

You now know the words SEO consultants use every day. Not to impress anyone at a tech cocktail party, but to understand how Google sees your firm. And to position your firm, literally and figuratively.

This SEO terminology is a foundation. You will come back to it, as much to understand a recommendation as to talk with an agency. What comes next?
