What is Link Velocity?
The rate at which a site gains (or loses) links over time. Unnatural spikes invite scrutiny; steady earned growth alongside real coverage is the healthy pattern.

Referring Domain
A unique site linking to you. Domain diversity matters more than raw link counts: 100 links from one site look like one relationship, not 100 votes.
Toxic Backlink
A link from spammy, hacked, or manipulative neighborhoods that risks association harm. Audit the pattern (site-wide footers, PBNs, injections) before reaching for the disavow file.
Digital PR
Earning editorial coverage and links with newsworthy data, tools, or stories. Citation hubs and original research are the repeatable assets behind most successful campaigns.
Off-Page SEO
Everything that builds a site’s reputation elsewhere: backlinks, mentions, reviews, and digital PR. Off-page signals validate what on-page content claims about expertise.
Link Equity
The ranking value passed through a link, shaped by the source’s authority, relevance, and number of outbound links. Internal links distribute equity; external links earn it.
PageRank
Google’s original link-graph algorithm scoring pages by the quantity and quality of inbound links. Still conceptually alive inside modern systems, even though the public score is long dead.
