iGaming link building (casino and sportsbook)
Online gambling is one of the most link-dependent markets in search. Fewer publishers accept it, the ones that do know what the links are worth, and the gap between a sustainable profile and a disposable one is wider than anywhere else.
Ecommerce link building (category and product pages)
Online stores earn their money on category and product pages, which almost nobody links to by choice. Ecommerce link building is the work of getting authority to those pages through PR, partners and internal links, without paying for anchors that look bought.
SaaS link building (and B2B tech)
Software companies earn links with things other markets do not have, such as free tools, product data and integrations. Publishers are cheap and risk is low. The usual failure is building links to the blog and never moving that authority to the pages that sell.
Local link building (single and multi-location businesses)
Local link building is small in scale. A few dozen referring domains from real organisations in your town can be enough. Citations are the baseline, and local news, sponsorships and partners make the difference.
Link building for lawyers and law firms
Law firm link building combines local search with some of the most expensive keywords anywhere. Legal directories are the base, and local news, bar associations, sponsorships and data studies are what separate firms on page one.
Finance link building (loans, insurance and fintech)
Finance links are expensive, heavily scrutinised and often legally an advert. Data-led digital PR and useful tools win here. Sponsored articles that make product claims without compliance sign-off are the costliest mistake.
Affiliate site link building (review and comparison sites)
Affiliate and review sites were built on bought links with commercial anchors. The sites that survived Google's recent updates look different, with brand searches, real authors and links from people citing their tests. Links no longer rescue a site Google judges unhelpful.
Crypto link building (crypto, forex and trading)
Crypto and trading sites lean heavily on sponsored coverage, and much of it does little. Fewer than half of publishers accept the niche, crypto media charge premium rates, and paid articles are financial promotions in several markets.
Health link building (supplements, CBD and vape)
Health is the strictest quality category in search. Medical results belong to institutions, while supplements, CBD and vape are commercial and prone to spam. Expert-led content earns the links that count, and advertising law decides which paid placements are allowed at all.
High-risk link building: how gambling, adult, pharma, crypto and loans do it
An analytical reference on how link building at volume and low cost works in restricted markets, what each tactic costs, how long it lasts and what it risks. It is not an endorsement. Methods that involve breaking into other people's websites are crimes, described only so you can recognise them.
Link building by industry
What works, what it costs and what it risks in each market. Publisher prices, restrictions and link profiles differ more between industries than most guides admit.
