When it comes to SEO, the most powerful tool to achieve great results is link building. Link building is essentially the backbone of search engine algorithms, making it the standard against which all sites are judged.

Search engines are designed to be judgmental, meaning their algorithms judge the authority of a site. Sites that are deemed authoritative and trustworthy are placed higher in search result rankings, while sites deemed to be spam barely register. In essence, these algorithms protect us from predatory websites by filtering out low-authority sites linking to spam, but that also means that site administrators must utilize link building best practices to maximize visibility.
