Transition Word Checker
See which sentences signal how they connect, grouped by the relationship each one expresses.
About this tool
Finds the transition words in a piece of writing and reports which sentences have one, grouped by what the transition actually does — contrast, cause, sequence, example.
You will have read that 30% of sentences should contain a transition. That number is one plugin's default setting; there is no study behind it and no search engine checks it. Writing to it produces prose stuffed with "moreover", which is worse than the problem it was meant to fix.
What is worth knowing is the grouping. A page where every transition is "additionally" is not well connected — it is repetitive, and a single percentage hides that completely.
English only.
Common questions
Is 30% the right target?
There is no evidence for it. The figure comes from a default threshold in a WordPress plugin and has been repeated until it sounds official. Well-edited published prose sits anywhere from roughly 15% to 40% depending on the material.
Do transition words affect rankings?
Not directly. No search engine has said it counts them. They affect whether a reader follows the argument, which is a better reason to use them.
Why group them by relationship?
Because a percentage treats "however" and "moreover" as interchangeable, and they are opposites. A page scoring well on volume while using one word repeatedly is the exact failure the score is supposed to prevent.
Does this work in other languages?
No. The lists are English, so anything else reads as zero. A zero here means "not checked", not "badly written", and the tool says so rather than reporting a failing score.
