A lawyer gets new clients through Google in three ways that work together: showing up organically for people who are searching (technical SEO and content), showing up in paid ads for people who are already ready to hire right now (Google Ads), and with a custom-built institutional website that turns that visit into a real contact. All of it within the advertising rules set by Brazil’s Bar Association (OAB) — informative, moderate, never promising a result and never turning the profession into a product. That exact combination took Dra. Ana Caroline Luminati, a criminal defense attorney in Mogi das Cruzes, from invisible on Google to +298% in website sessions in one month. In this post, without skipping a step, the technical walkthrough of how it was built.

Why Google works better for a lawyer than Instagram or other social networks

Social media is passive discovery: the person is scrolling their feed, not necessarily needing a lawyer at that exact moment. A Google search is the opposite — it’s active intent. Someone typing “criminal defense lawyer in Mogi das Cruzes” already has a concrete legal problem, and is often under real pressure: an arrest, a hearing already scheduled, a deadline running out.

That’s reinforced by the sheer size of Google itself: the search engine holds 96.17% of the search engine market share in South America, far ahead of any alternative. And specifically in the legal sector, industry research shows that roughly 96% of people search for legal services online before making any hiring decision. Put the two together: the decision happens on Google, and that’s where a law firm needs to be — not just on Instagram.

Within OAB’s rules: informative advertising, not a commercial pitch

All of this work was built around Provimento (Ruling) 205/2021 from Brazil’s Federal Council of the OAB, which regulates advertising, promotion and information in the legal profession. The logic of the rule is clear: it expressly allows digital legal marketing — website, blog, social media, even paid promotion — but the advertising has to be informative and moderate, never commercial. In practice, that’s what shaped what went in and what stayed out of the strategy:

• What went in: educational content (the blog answers real legal questions), an institutional presentation of the attorney and her practice areas, contact details, technical structure (SEO, legal schema markup).
• What stayed out: promises of outcome (“guaranteed win,” “guaranteed result”), comparisons with other lawyers, any language that makes the legal profession sound like a product for sale.

That same care applies to both the blog’s organic content and the paid ads — paid traffic for lawyers is allowed under OAB rules, as long as the ad is institutional and doesn’t promise a case outcome.

A custom-built institutional website, in the firm’s own visual identity

No generic template. The website was designed from scratch around Dra. Ana’s own brand — the color palette, typography and visual tone that already represented her, not a layout recycled from another client. Structure: homepage, about the attorney, practice areas explained without legal jargon, blog and contact — all in two languages (Portuguese and Spanish), so as not to lose the part of the audience that searches in Spanish.

Technical SEO: the foundation of organic growth

Behind the site: structured data (legal schema markup, which tells Google “this is a law firm, with these specialties”) and metadata configured on every individual page. That technical work, invisible to anyone visiting the site, is what makes Google understand what each page is about and show it for the right query.

The results on the organic side show up in the site’s own traffic report: the organic channel accounted for 41.5% of sessions in the period, with 54.3% engagement and 44 seconds average time on page — the highest of any channel. That’s a sign that people arriving organically are actually reading, not just glancing.

Paid traffic: capturing the people who are deciding right now

While organic builds authority over the long run, paid (Google Ads, institutional, within OAB rules) captures people who have already made the decision. In the same period, the paid channel accounted for 37.4% of sessions, but concentrated 78% of all WhatsApp clicks (67 of 86) — 14.1% of people who arrived via paid clicked the contact button, against 2% for organic. Average time on page was just 8 seconds: these are people who don’t stick around to read, they decide and reach out.

The result, combining both fronts

In one month, website sessions jumped from 170 to 677 (+298%), generating 86 clicks on the WhatsApp button straight from the page. Of those contacts, 9 were qualified leads — real criminal-law demand, not questions outside the firm’s practice areas — and 3 have already become signed contracts with the firm. Traffic growth with no real conversion isn’t worth anything; that’s why this last number matters just as much as the first. See all the numbers in the full case study.

FAQ

Can a lawyer run paid ads on Google?

Yes. Provimento 205/2021 from the OAB expressly allows digital legal marketing and paid content promotion, as long as the advertising is institutional and informative — no promised outcome, no comparison with other professionals, and no turning the profession into a commercial pitch.

Paid or organic: which works better for a lawyer?

Both, together. Organic builds long-term authority and brings people who genuinely read and trust you; paid shows up right away for people who have already decided and are in a hurry. On their own, each one only covers half the funnel.

How long does it take for a law firm website to show up on Google?

Technical SEO (indexing, showing up in searches for the attorney’s name and specialty) usually shows the first signs within weeks. Consistent, growing results depend on new content going out regularly — it’s an ongoing process.

Does a law firm need a blog on its website?

If the goal is to reach people who don’t know the firm yet, yes — the blog is what answers the questions people are already typing into Google before deciding to hire a lawyer.

Can this be done alone, or do you need an agency?

It can be done alone, if you have the time to learn technical SEO, keep up with OAB’s advertising rules, produce content regularly and manage paid traffic. For a lawyer who wants to focus on practicing law, a specialized agency delivers faster, with less risk of advertising that falls outside the rules.
