Link Advise and Concepts

How To Do Link Building If You Are Just Starting Out In Business

Healthcare: Nurses, Clinicians, Mental Health Experts

Let’s say you’re a newly certified nurse practitioner launching a private women’s health consultancy. You’ve just built your site, but it’s nowhere near page one—classic Google sandbox behavior. For medical content, trust is everything, and Google weighs E-E-A-T (Experience, Expertise, Authoritativeness, Trust) heavily.

Case Insight: When we analyzed the top-ranking NP websites in New York (via Ahrefs), we saw sites like midtownwomenshealth.com had over 1,400 backlinks. Top referrers included Healthgrades, Psychology Today, and university-hosted directories (edu links!).

Best Practices:

Pro Tip: For mental health pros, backlinks from state licensing boards or continuing ed sites like CEUFast or APA.org can immediately build credibility and trust signals.

Trades: HVAC Pros, Plumbers, Auto Technicians

As an HVAC manager or auto shop owner, most traffic is local—but local SEO still needs links. Google trusts you more when other local or industry-related websites link to you.

Scenario: You’re a master HVAC contractor trying to outrank a competitor in your city. That competitor’s site has 200+ links from manufacturer warranty registries, vocational schools, and project directories like HomeAdvisor.

Best Practices:

Pro Tip: Submit "how-to" or “seasonal HVAC checklist” articles to local newspapers and niche YouTube channels. You’ll not only get backlinks but also referral traffic from highly engaged readers.

Teaching and Academics: Course Creators, EdTech Platforms, Schools

If you're an academic launching your own course on a platform like Teachable or a K-12 educator building curriculum content, link building should focus on trust, collaboration, and open-access sharing.

Example: We looked at sciencemom.com, a site run by a homeschool educator. Over 3,200 backlinks, with major sources like National Geographic Kids, Coursera, and school district websites linking to her experiments page.

Best Practices:

Pro Tip: Build academic backlinks by creating downloadable toolkits (e.g., "AI for Middle Schoolers") and reaching out to professors or student forums that link to resources.

Service Sector: Massage Therapists, Stylists, Tattoo Artists

Here, your best links come from lifestyle magazines, visual platforms, and hyper-local business directories. You’re not trying to rank nationwide—you want your city or neighborhood to find you first.

Example: inkedmag.com links to over 80 tattoo artists annually through interviews and portfolio roundups. Stylists get featured on Byrdie, Allure, or even wedding blogs showcasing their work.

Best Practices:

Pro Tip: Tattoo artists and stylists often earn links via Instagram mentions—convert that into backlinks by embedding gallery feeds on third-party blog features.

Leadership and Organizational Strategy: CEOs, HR Managers, Policy Leads

If you're in executive leadership, HR, or ethics, authority comes from thought leadership. Link building here means syndication, whitepapers, and being cited in trusted business sources.

Scenario: A DEI leader writing about inclusive hiring might aim for backlinks from HR platforms, legal compliance sites, and nonprofit think tanks.

Best Practices:

Pro Tip: Publish your own proprietary frameworks (e.g., “Inclusive Conflict Resolution Model”), offer them to academic institutions, and ask for citation links.

Green Industries: Farmers, Environmental Engineers, Conservation Scientists

If you’re in environmental work, you’re in a data-driven field. This means your strongest links come from research orgs, .gov databases, and nonprofit partner networks.

Example: regenerativefarmers.org gained .edu and .org links by open-sourcing soil carbon data and publishing it on USDA forums and cooperative extensions.

Best Practices:

Pro Tip: Create map-based content (e.g., “Top Organic Farms in Kansas”) and submit to regional food sustainability networks who often backlink.

Public Service & Emergencies: EMTs, Firefighters, Social Workers

Backlinks for public sector roles should reinforce your position as a trusted, informed authority. Think .govs, nonprofit sites, health NGOs, and educational outreach campaigns.

Example: firstrespondermentalhealth.com saw a huge bump in domain authority when linked by NAMI.org, SAMHSA, and 911 dispatcher support groups.

Best Practices:

Pro Tip: Many NGO newsletters will link to responder-authored content during awareness months (e.g., PTSD Awareness Month).

Infrastructure: Linemen, Plant Operators, Technicians

In technical roles, backlinks come from compliance sites, union directories, safety blogs, and engineering content hubs.

Example: A nuclear plant technician’s blog on reactor maintenance earned .gov and .edu backlinks by being cited in occupational safety manuals.

Best Practices:

Pro Tip: Sponsor vocational training scholarships and ask host organizations to backlink your firm as a community partner.

Spirituality and Ethical Thought: Pastors, Interfaith Workers, Chaplains

Faith-based content builds authority when shared in respectful, interfaith or academic contexts. Sermons, devotionals, and ethical essays perform well on journal or nonprofit sites.

Example: A seminary blog series on “Faith in Crisis” was picked up by Patheos and five Christian university departments.

Best Practices:

Pro Tip: Build ethical whitepapers (e.g., “AI and the Soul”) and get cited by university theology labs or public lectures.

Communication: Journalists, Podcasters, Moderators

In media, link building is visibility. You need syndication, guest features, and being quoted in breaking stories.

Example: A podcast assistant gained 140+ backlinks by creating a guide called “The Podcast Producer’s Toolkit” — cited by Podnews, Buzzsprout, and five radio networks.

Best Practices:

Pro Tip: Submit media explainers (e.g., “How Fact-Checkers Verify AI Content”) and get cited in university journalism courses or press associations.

Final Word: Link Building with Precision

The #1 mistake businesses make is trying generic tactics for a specialized space. In 2025, precision wins. Know your sector, study top-ranking competitors, give people content they can cite—and let the links come to you.
