GLOSSARY
SEO and AI search terms, in plain English.
Reference definitions for the terms we use across our services and blog. No jargon left unexplained.
- AEO (Answer Engine Optimization)
- Optimizing content so it can be directly cited or quoted by AI systems like ChatGPT, Perplexity and Google AI Overviews, rather than just ranked in a list of links.
- Backlink
- A link from another website pointing to yours. Search engines treat backlinks from credible sites as a signal of trust and authority.
- Canonical URL
- The version of a page's URL that a site owner wants search engines to treat as the primary one, used to avoid duplicate-content confusion when several URLs show similar content.
- Core Web Vitals
- Google's set of metrics for measuring a page's loading speed, interactivity and visual stability, used as one input into search ranking.
- Crawlability
- How easily search engine and AI bots can discover, access and read the content on a site. Poor crawlability means content can exist but never get indexed.
- Featured Snippet
- A highlighted answer box shown at the top of some Google search results, pulled directly from the content of a ranking page.
- Indexation
- The process by which a search engine adds a page to its searchable database after crawling it. A page can be crawled but still not indexed.
- JSON-LD
- A structured data format used to describe page content, such as an Organization, Article or FAQ, in a way machines can parse directly rather than inferring it from prose.
- Keyword Difficulty
- An estimate of how hard it would be to rank for a given search term, based on the strength of the pages already ranking for it.
- llms.txt
- An emerging convention, similar in spirit to robots.txt, that gives AI systems a plain-text summary of a website's key pages and purpose.
- On-Page SEO
- Optimizing individual page elements, such as title tags, headings, content and internal links, to help that specific page rank for relevant searches.
- PSG (Productivity Solutions Grant)
- A Singapore government grant, administered through the Business Grants Portal, that can subsidize part of the cost of eligible pre-approved digital solutions for qualifying local SMEs.
- Robots.txt
- A file at the root of a website that tells search engine and AI crawlers which parts of the site they're allowed to access.
- Structured Data
- A standardized format, most commonly schema.org, for labeling page content so search engines and AI systems can understand it precisely instead of reading it as plain text.
- Technical SEO
- The behind-the-scenes work, such as site speed, crawlability, structured data and indexation, that lets search engines properly access and understand a site in the first place.
