Related term lists inserted as "LSI keywords"

What it is

Pages contain blocks or comma separated lists of related terms, or sentences that exist only to include synonyms, added on the belief that Google rewards LSI keywords. Google has not confirmed any use of LSI and John Mueller has said LSI keywords have no effect. Inserted term lists add nothing for readers and match Google's description of keyword stuffing.

Why does related term lists inserted as "lsi keywords" matter for AI search?

Google has not confirmed any use of LSI and John Mueller has said LSI keywords have no effect. Inserted term lists add nothing for readers and match Google's description of keyword stuffing.

How do you fix it?

Delete term lists and forced synonym sentences. Where a related concept is genuinely missing, cover it in a proper sentence or section.

How do you find it on your site?

  1. Search the CMS, briefs and content templates for the phrases "LSI" and "LSI keywords" to find where the practice is in use.
  2. Crawl the site and extract main content; flag paragraphs with a high share of comma separated noun phrases and no verbs.
  3. Check meta keywords, alt text and hidden elements for related term lists.
  4. Manually review flagged pages for sentences that add a synonym but no new information.

Which ranking and citation factors does it touch?

Written for the Latent semantic indexing (LSI) page (evidence: General theory). Google has not documented this system in a way a site can test directly, so this check measures a proxy for it, not the system itself.

What is the impact?

Indirect. Estimate only: little upside from removal alone, but it removes a keyword stuffing risk and improves readability.

What is the evidence?

John Mueller's 2019 and 2023 statements reported by Search Engine Roundtable; Google spam policies on keyword stuffing.
