Off-Page Optimization

Off-page optimization is the work done anywhere other than a site’s own pages to raise its standing: links from other sites, mentions of the business by name, directory listings, reviews on third-party platforms and press coverage. Its subject is the business’s reputation elsewhere, which search engines and AI assistants both read.

Links, and how they are qualified

A link from another site is the oldest off-page signal and the one search engines document most. Google’s guidance on qualifying outbound links describes three rel values a linking site can attach: sponsored for paid placements, ugc for user-generated content such as comments, and nofollow when the site would rather not be associated with the destination. Links carrying any of them are, in Google’s words, generally not followed, though the destination may be found through other routes. A listing or an article that links to you with one of these attached still puts your name in front of a reader and a crawler; it just does not vouch for you.

Mentions without links

An assistant composing an answer does not tally links. It reads pages, and what it can do with a business is corroborate it: the same name, the same location, the same trade appearing on the business’s own site, on a directory, in a review platform and in a local news piece. Each unlinked mention is one more page saying the same thing. In this site’s one-question probe of 9,240 small businesses, put to Claude with retrieval, 99.4% of the names the assistant returned were businesses and 0.6% were directories or aggregators; the assistant read the aggregators and named the businesses on them. That is a Claude number from one day, reported in the 9,483-site audit, and it describes where the answer pointed rather than where the assistant looked.

The boundary with on-page work

Off-page work can make a business found. It cannot make the business’s own page say anything. A directory listing that carries the right phone number next to a website that carries two different ones has produced a contradiction, not a signal, and the page the assistant fetches last wins.

A common question

Is an unlinked mention of a business worth anything to an AI assistant?

An assistant does not add up links. It reads pages, and what it can do with a business is corroborate it, so each unlinked mention is one more page carrying the same name, the same location and the same trade. A directory entry or a review platform that never links to the site still counts for that. What it cannot do is settle a contradiction: a listing with the right phone number beside a site carrying two different ones leaves a conflict rather than a signal, and the page fetched last decides.
