Link Building for Law Firms: Ethical Strategies That Work
Backlinko’s 2020 analysis of 11.8 million search results found that the number one result in Google has, on average, 3.8 times more backlinks than pages ranking in positions two through ten. That study is now six years old, and the exact multiplier may have shifted as Google’s algorithm evolves — but directional data from Moz, Ahrefs, and Semrush continues to confirm that the correlation between backlink volume and top rankings remains strong. The principle holds even if the precise ratio has changed. Most law firm marketing teams know backlinks matter. What they rarely examine is how many of their existing backlinks actually contributed to rankings versus how many just exist as dead weight.
Moz’s search ranking factors research and Whitespark’s local ranking factors survey both consistently place backlinks among the top-weighted signals for both organic and local results — the exact percentage varies by model, but backlinks typically rank in the top three factors across major SEO studies. Yet for law firms specifically, the link building playbook looks different from most industries. Paid link schemes carry higher risk because legal sites operate under YMYL scrutiny. Guest post farms are increasingly penalized. And the “spray and pray” approach of submitting to hundreds of directories produces diminishing returns long before you finish the list.
What works is slower, harder, and more effective.
Bar Associations, Legal Directories, and Local Partnerships: Where Links Actually Come From
The link opportunities that produce measurable ranking impact for legal sites fall into a few categories. None of them involve buying links, and all of them require either expertise, relationships, or content worth referencing.
Bar association and legal organization memberships. State and local bar associations typically maintain member directories that include links to member websites. These are legitimate, editorially controlled links from high-authority .org domains. National organizations like the American Bar Association, specialty bars, and practice-specific organizations (American Association for Justice, National Association of Criminal Defense Lawyers) offer similar directory listings. The links are often nofollow, but as multiple SEO analyses have noted, nofollow links from authoritative legal sources still provide referral traffic, brand visibility, and a natural link profile that Google expects to see for legitimate law firms.
Legal directories with editorial standards. Justia, Avvo, FindLaw, and Best Lawyers are the directories that consistently appear in analyses of effective legal backlinks. Justia’s own documentation on citation and link building for legal SEO, published May 2025, notes that backlinks from well-regarded legal platforms such as law school journals, legal blogs, and online legal directories hold significant value, and academic and government websites carry particularly high authority. The key distinction is between directories that verify listings and maintain quality standards versus directories that accept any submission. The former are worth your time. The latter are noise.
Local partnerships and sponsorships. A link from the local chamber of commerce, a community nonprofit you sponsor, or a local business association carries geographic relevance that amplifies your local SEO signals. When your firm sponsors a legal aid clinic, the clinic’s website often lists sponsors with links. When you speak at a local business event, the event page links to your bio. These links are valuable precisely because they are locally relevant and editorially placed, not because of high domain authority metrics.
Academic connections. Law school alumni associations, university career services pages, and continuing legal education programs provide .edu link opportunities that carry significant authority. Some firms create scholarship programs specifically to earn .edu backlinks, and while Google has cracked down on purely transactional scholarship link schemes, a legitimate scholarship with real selection criteria and actual awards can produce sustainable .edu links that remain valuable.
Link Velocity: What Sustainable Growth Looks Like
A mid-size law firm in a competitive market does not need hundreds of new links per month. It needs a consistent, sustainable velocity that matches or slightly exceeds what competitors are acquiring.
The way to determine your target: use Ahrefs or Semrush to examine the backlink growth rate of the firms currently ranking in positions one through three for your primary keywords. If those firms are gaining roughly five to ten new referring domains per month, that is your benchmark. You do not need to match it exactly, but your growth rate should be in the same range, not an order of magnitude lower.
What matters more than hitting a specific number is maintaining consistency. A firm that acquires three quality links per month for 12 straight months builds a more natural-looking profile than a firm that acquires 36 links in a single month and then goes quiet. Sharp spikes in link velocity can trigger algorithmic scrutiny, particularly for YMYL sites where Google is already watching more carefully. Sharp drops signal that whatever was generating links stopped working, which can also raise flags.
The realistic cadence for most mid-size firms investing in link building: two to five new referring domains per month from a mix of directories, local partnerships, content-driven editorial links, and professional association listings. That pace compounds over 12 to 24 months into a competitive backlink profile without triggering the patterns that suggest manipulation.
Evaluating Whether a Link Opportunity Is Worth Pursuing
Most are not. That is the uncomfortable starting point. The evaluation framework that prevents wasted time has three filters.
First, relevance. A link from a legal blog, a local news outlet covering your community, or a professional organization in your practice area carries topical relevance that a link from a random lifestyle blog does not. Google weights relevant links more heavily in its ranking calculations, and for YMYL legal content, the relevance threshold is higher. A criminal defense firm gains more from a link on a criminal law resource page than from a link on a general business directory.
Second, authority. Domain Rating (Ahrefs) or Domain Authority (Moz) provide rough benchmarks. For legal link building, a DR of 30 or higher is generally worth pursuing if the site is topically relevant. A DR of 50 or higher from a relevant legal source is a high-value opportunity. But do not chase metrics blindly. A legal blog with DR 35 and genuine readership from legal professionals is more valuable than a generic directory with DR 60 that no human actually visits.
Third, link farm detection. Some sites disguise themselves as legal resource pages while operating as link farms. Red flags: the site accepts guest posts from any industry with minimal editorial review, the site has an unusually high ratio of outbound links to content, the site’s traffic (check via Semrush or SimilarWeb) is near zero despite a seemingly high domain authority, or the site’s backlink profile consists primarily of other link farm sites. One link from a detected link farm can trigger manual action review for your entire domain. The stakes for YMYL sites make this filter non-negotiable.
Digital PR Angles That Earn Editorial Links
The highest-value links for law firms are editorial links: a journalist, blogger, or publication linking to your site because your content or expertise added value to their story. These are the hardest to earn and the most impactful for rankings.
The angles that work for law firms fall into two patterns.
Data-driven legal content. Original research, surveys, or data analyses related to legal topics generate media interest because journalists need numbers to anchor their stories. A firm that compiles data on average settlement amounts in a specific practice area, analyzes trends in local court filings, or surveys consumer attitudes about legal processes creates a citable asset. The content needs to be genuinely original, because journalists verify before citing, and it needs to be presented clearly with methodology disclosed.
Expert sourcing. Platforms like HARO (Help a Reporter Out), Connectively, and similar journalist-request services allow attorneys to respond to media queries as expert sources. When a journalist writes a story about changes in employment law and quotes your attorney with a link to your firm’s website, that is an editorial endorsement from a news domain. The success rate is low per query, but attorneys who respond quickly, concisely, and with genuine expertise develop relationships with journalists who return to them as reliable sources. Consistency matters: responding to two or three relevant queries per week over several months produces more results than a burst of activity followed by silence.
The timeline for editorial link building is measured in months, not weeks. A firm that starts a consistent digital PR effort today should expect to see the first meaningful editorial links in three to four months, with cumulative ranking impact becoming visible at six to twelve months. This is a compounding strategy. Each link builds authority that makes the next link easier to earn, because journalists and publications prefer to cite sources that already have a visible track record.
What this costs: in-house link building requires five to fifteen hours per month of consistent effort — responding to journalist queries, writing guest contributions, maintaining bar association and local business relationships. If that time does not exist internally, an agency or freelance digital PR specialist runs $1,000 to $3,000 per month for a legal-focused link building program. The critical number is not cost but consistency. A three-month burst followed by silence produces fewer results than twelve months of steady, modest effort.
The approach differs by firm size. A solo practitioner should focus on the zero-cost, high-credibility tactics: bar association profiles, local business organization memberships, and responding to HARO or Connectively queries two to three times per week. The time investment is three to five hours per month. A mid-size firm can add guest contributions to legal publications, local event sponsorships with web citations, and strategic partnerships with complementary professionals (financial advisors, medical providers, real estate agents). A large firm with marketing resources should run a full digital PR program including original research, data studies, and proactive media outreach — the kind of content that generates links at scale because it is genuinely useful to journalists.
Link building works best when E-E-A-T signals are already in place. A journalist is more likely to cite an attorney who has a complete bio page with credentials, publications, and case experience than an anonymous “firm spokesperson.” The E-E-A-T post covers how to build that foundation.
Sustainable backlink profiles come from treating link building not as a separate project but as a byproduct of doing what you already do well: demonstrating expertise, participating in your professional community, and creating content worth referencing.
Here is the math that makes this concrete. The difference in backlinks between a position-one result and a position-five result is roughly 3x, per Backlinko’s data (noting that this figure dates to 2020 and the exact ratio may have shifted, though the directional relationship remains well-supported by current research). If your top competitor acquires five referring domains per month and you acquire zero, the gap widens by 60 domains per year. That is 60 endorsements of their authority that your site does not have. Every month without a link building effort is a month that gap compounds.
