Transitions signal a relationship, not a style
A transition word tells the reader what relationship the next sentence has to the last one: it adds, contrasts, concludes, gives an example, or shows cause. When the relationship is obvious from the content, the word is redundant. When it is not obvious, its absence makes the reader work out the connection themselves, and a reader who has to do that for every sentence gives up. The useful question is not how many transitions a text has but whether the ones present match the relationships actually being expressed.
The wrong transition is worse than none
"However" between two sentences that agree, or "therefore" where nothing follows from what came before, actively misleads. The reader trusts the signal and reads the next sentence expecting a contrast or a conclusion that is not there. This is more damaging than a missing transition, because the reader has to detect and discard a false expectation rather than simply construct a connection.
Guidelines and thresholds
Some writing advice sets a target of thirty percent of sentences containing a transition word. The number originates from readability heuristics used in content scoring tools, not from research showing thirty percent is optimal. Treat it as a prompt to check whether connections are clear, not as a target to hit, because writing that pads to reach a percentage reads worse than writing that does not.

Frequently Asked Questions
What proportion of sentences should contain a transition?
Some content scoring tools use thirty percent as a threshold, but the number comes from readability heuristics rather than from evidence that it is optimal. Use it as a prompt to check whether the connections between sentences are clear, not as a quota to fill.
Can there be too many transitions?
Yes. When the relationship between two sentences is already obvious, the transition word adds length without adding meaning, and a text where nearly every sentence opens with one reads mechanically. Consecutive sentences starting with the same connective are the clearest symptom.
What kinds of transition are there?
Additive ones add information, adversative ones contrast, causal ones show cause and effect, sequential ones show order, exemplifying ones introduce an example, and concluding ones summarise. Matching the category to the actual relationship matters more than the count.
Is a wrong transition worse than a missing one?
Yes. A reader trusts the signal, so "however" between two agreeing sentences creates a false expectation that has to be detected and discarded. A missing transition only requires the reader to construct the connection themselves.
Do transitions have to start the sentence?
No. They can appear mid sentence, and varying their position avoids the mechanical rhythm of every sentence opening the same way. This tool reports sentence initial and mid sentence occurrences separately for that reason.
