Link building for lawyers can involve creating content that specifically focuses on legal topics, and then reaching out to relevant websites and blogs to request backlinks to this content. This can be done by researching websites and blogs in the legal industry, creating content that is optimized for search engines, and then contacting the webmasters to request links to the content. Link building can help make content appear more authoritative and higher in the rankings, but the quality and relevance of links is more important than the quantity.
