SEO glossary
What are long-tail keywords?
Long-tail keywords are specific search terms that each get relatively few searches, such as "quiet dishwasher for open plan kitchen" rather than "dishwasher". They are usually easier to rank for, show clearer intent and, added together, make up a large share of all searches. Most are three or more words long, but length is not the definition.
Related SEO terms
A seed keyword is a short starting term, like "coffee" or "CRM", that you expand into a longer list of keyword ideas during keyword research.
Question keywords are searches phrased as questions, like "how do solar panels work". They often trigger featured snippets and People Also Ask.
Keyword clustering is grouping keywords that share intent and search results, so each group can be targeted by one page.
Search intent is the reason behind a search: what the person wants to know, find or do. Matching it is one of the most important parts of SEO.
A keyword trend shows how searches for a keyword change over time, usually month by month, so you can spot growth, decline and seasonal peaks.
Keyword ideas FAQ
What is the difference between matching and related terms?
Matching terms contain the topic of your seed. Related terms are what people also search around it, which often brings up angles the seed does not contain.
Do I need a project?
No. The SEO tools work on their own, in any market you pick. Keywords you find can be saved to a project in one click when you want to track them.
Can I share a result?
Yes. The search, the market and the open tab are all in the page address, so a link or a bookmark opens the same view. Anyone opening it runs the search with their own key; a repeat of something already looked up is served from the cache for free.
