Law firm blog topics are the subjects a firm chooses to publish on its blog, and the choice decides whether the blog produces consultation requests or just traffic.
This list is the topic layer of law firm content marketing; here the question is which posts are worth writing at all.
Posts are also one layer of law firm SEO: they catch the question searches, while your practice-area pages catch the ones closest to hiring.
Should a law firm blog at all?
A blog works when it is a library of answers to the questions people in your practice areas search before they hire, and it sits idle when it is a feed of firm announcements.
"Should law firms blog" is really a question about topics, because the same firm can run a blog that books consultations and a blog nobody reads.
Nielsen Norman Group's 2016 study of service-business websites (not law firms) names comprehensive and current content as one of four credibility factors, and found that sites omitting basic information were almost immediately ruled out of consideration.
ABA Formal Opinion 10-457 (August 5, 2010) adds the maintenance floor: lawyer website content should be updated regularly.
The blog post ideas that bring consultations
Nearly every post that produces a consultation request is one of six question types, each written for one practice area and one jurisdiction.
Cost questions
What a case type costs, and the factors that move the number up or down.
Timeline questions
How long a custody case, a probate estate or an immigration petition takes, and what moves it.
Decision questions
"Do I need a lawyer for this?" posts catch people early, and an honest answer, including when it is no, earns the next click.
Scenario questions
The situations intake hears weekly: the crash with an uninsured driver, the first DUI, the inheritance with debts.
Process questions
What happens at the first consultation, the arraignment or the interview, so the reader knows what to expect.
Mistake questions
The mistakes that sink a claim or a filing, written as warnings with the fix.
The common structure: a real question, the jurisdiction named, the answer in plain language, and a way to reach the firm at every scroll.
Blog topics that waste the time
Firm news, awards and new hires draw no searches; they belong on the About page or in a law firm newsletter for people who already know the firm.
Case summaries and case-law commentary are written for other lawyers, not for the prospective clients searching before they hire.
The bulk pattern is the one Google polices outright: its helpful-content self-assessment (last updated October 1, 2026) lists "extensive automation to produce content on many topics" and content produced in hopes that some of it might perform well among its warning signs.
Its spam policies (last updated August 28, 2026) go further and define scaled content abuse as generating many pages mainly to manipulate rankings, "no matter how it's created", with generative-AI pages produced without adding value among the named examples.
A 500-title list does not fix a topic problem; it industrializes it.
Where law firm blog topics sit
- Cost and timeline questions
- Do I need a lawyer posts
- Scenario and process posts
- National legal news roundups
- Case-law commentary
- Firm news and awards
Legal blog ideas by practice area
The patterns swap by practice area, and the jurisdiction belongs in every title.
-
Personal injury: the crash with an uninsured driver, the first week after an accident, how a settlement gets calculated.
-
Family law: how custody is decided in your state, who keeps the house, what mediation involves compared with trial.
-
Criminal defense and DUI: what happens at arraignment, license consequences of a first DUI, dismissal versus reduction.
-
Estate planning and probate: whether a will avoids probate, what an executor does and by when, no will at all.
-
Immigration: how a green card interview runs, what a denial means for a pending application, renewals and timelines.
-
Bankruptcy: chapter 7 versus chapter 13 in plain words, what happens to the house, which debts survive a discharge.
-
Employment: a firing you believe was retaliation, overtime rules for a job, the deadlines that start the day something happens.
Treat these as patterns: the topics that work for your firm are the ones your intake log confirms.
Each is only worth publishing when a lawyer at the firm can supply the jurisdiction-specific answer; who drafts and who reviews is covered in legal content writing.
Three topic types that need a lawyer before a writer
Client stories and case results. ABA Formal Opinion 480 (March 6, 2018) says lawyers who blog, post or otherwise comment publicly may not reveal information relating to a representation, including information in a public record, unless a Model Rule authorizes it, so the client-story post arrives with a consent workflow attached.
Formal Opinion 10-457 (August 5, 2010) adds that naming current or former clients requires their informed consent.
The specialization title. Certification rules differ by state, and the Model Rules moved in 2018: the ABA deleted Model Rules 7.4 and 7.5 that August and moved certification provisions into Rule 7.2 and the Rule 7.1 comments, per the ABA CPR Policy Implementation Committee's October 25, 2018 letter, though some states still number their versions 7.4 and 7.5.
That is a reason to re-read old posts, not a guide to specialist advertising, which your state's rule controls.
The missing name and contact line. ABA Model Rule 7.2(d) requires every communication made under the rule to include the name and contact information of at least one lawyer or law firm responsible for its content, and counts a website, phone number, email address or physical office as contact information.
Some states still require a street address or a city, and the Model Rules bind no one until a state adopts them, so the firm's own state rule controls.
It is also the cheapest conversion fix on a blog: a post that answers the question and hides who to call wastes the topic.
Confirm the topic-specific questions with your state bar's ethics counsel or an ethics lawyer.
Blog topics in the AI-search era
Nothing about AI changes the topic list: Google's guide to optimizing for generative AI features (added May 2026, last updated July 2026) says optimizing for its generative AI search is still SEO, and that Google Search ignores llms.txt files, needs no "chunked" content and requires no special schema markup.
Google does tell site owners to use Search Console's Generative AI performance report to see how content performs in generative AI features on Search and Discover.
The deeper playbook is in AI search for law firms.
How to build the backlog
List the questions the last two weeks of consultations opened with, in the callers' words.
Search Console's query report shows which have search demand and where the site already ranks on page two.
The questions that decide the hire belong on a practice-area page, with posts feeding it; the law firm practice area pages guide draws that line.
Then cut the backlog to what you can keep current, because twelve posts you keep accurate beat fifty titles in a spreadsheet.
Once posts are live, the numbers that matter are consultation requests by post and the signed cases behind them, not sessions; the measurement setup is in consultation to signed case rate.
Frequently asked questions
What should a law firm blog about?
Questions people search in the weeks before they hire a lawyer: what something costs, how long it takes, whether a lawyer is even needed, and what happens next, each written for one practice area and one jurisdiction.
Do law firm blogs bring clients, or just traffic?
They bring clients when every post answers a question a prospective client searched on the way to hiring, and they sit unread when the blog is firm news and case commentary for other lawyers. Judge posts by consultation requests and signed cases, not sessions.
Where do law firm blog ideas come from?
The questions intake answers every week, the question queries in Search Console, the questions people ask on your Google Business Profile, and the gaps between the practice areas you handle and the pages your site covers.
Should a law firm blog about changes in the law?
Yes when the change moves something a prospective client cares about, such as a filing deadline or a benefit amount, and no when the post is commentary aimed at other lawyers. Put the state and the date in the post, because legal content goes stale fast.
Should a small firm without a blog start one?
Only with topics drawn from its own practice areas and intake questions, on a cadence it can keep current: ABA Formal Opinion 10-457 (August 5, 2010) says lawyer website content should be updated regularly, and stale posts spend the trust the content was meant to build.
