Transition words for SEO: the complete list by category

What is a transition word in SEO?

A transition word is a linguistic connector that sets up a logical relationship between two sentences, two paragraphs or two ideas.

It does three jobs. It guides the reader from one idea to the next. It makes the structure of the reasoning explicit. And it signals to search engines and language models alike how your arguments connect.

That last point has grown in importance. A generative engine that extracts a passage to answer a question needs to understand where an idea starts and where it ends. Explicit connectors give it those boundaries.

One important point up front: transition words are not a ranking factor. No one at Google has ever said otherwise. They work indirectly, by making the text more readable, and readability influences time on page, reading depth and the likelihood that a passage gets picked up elsewhere.

Why it matters for SEO

The effect is indirect, and it is important to say so clearly rather than promise a gain in rankings.

Readability

The Flesch reading ease score rates a text from 0 to 100: the higher the score, the easier the text is to read. Connectors mechanically improve this score by reducing the effort needed to move from one idea to the next.

A text that reads effortlessly is a text people read to the end. That is the whole benefit, and it is more than enough to justify the exercise.

Behavioral signals

Google indirectly observes user satisfaction: do people return to the search results right away, or keep reading? A smooth text holds attention longer than a choppy one.

Google's official position, repeated by its spokespeople, is that readability is not a ranking factor as such. It does, however, influence everything users do once they land on the page.

Extraction by generative engines

ChatGPT, Perplexity and Google's AI Overviews extract passages to build their answers. An explicit connector such as "as a result" shows where the conclusion of a line of reasoning sits, which makes the passage easier to isolate cleanly.

It is the only area where the effect of connectors has clearly grown in importance over the past two years.

How Yoast evaluates your transitions

Yoast SEO calculates the percentage of sentences that contain at least one connector from its database. The traffic-light system is simple:

• Green: 30% of sentences or more contain a transition word.
• Orange: between 20% and 30%.
• Red: less than 20%.

Yoast also evaluates other readability criteria: sentence length, the share of passive voice, paragraph length, repeated sentence openings and heading hierarchy.

A useful warning: this threshold is a convention of the tool, not a Google rule. Aiming for green is a good safeguard; making it an absolute goal produces mechanical text.

Other tools

• Hemingway Editor: flags sentences that are too long or too complex, beyond connectors alone.
• Antidote: a writing assistant that is the most relevant for French-language text when checking how sentences flow.
• Surfer SEO: compares your structure with that of pages that already rank well.

The three-step method

The worst way to go about it is to think about transitions while writing: the text becomes rigid and you can hear the effort. Here is the order that works.

1. Write without thinking about it. Lay out the ideas, in order, without worrying about the links between them.
2. Reread looking for breaks. Every place where the reading snags signals a missing link.
3. Add the connector that matches the actual relationship: addition, cause, consequence, contrast. Not the one that sounds good: the one that is accurate.

This third step is the one people rush. A "however" placed where there is no contrast confuses the reader, and signals to the model a contradiction that does not exist.

Where to place them first

• At the start of a paragraph: to connect it to the previous paragraph.
• Before an example: "for example", "in practice".
• Before the conclusion of a section: "as a result", "that is why".
• Before a data point: naming its source in the same sentence.

Adjusting density to the format

The 30% threshold applies to an in-depth article. Elsewhere, it works against the text:

• Blog post: around 30%.
• Product page: much less, because the text is descriptive, not argumentative.
• Landing page: the minimum, because short messages live on their rhythm.
• FAQ: somewhere in between, since each answer must stand on its own.

The five most common mistakes

• Overuse: a connector in every sentence weighs the text down as much as having none. If a sentence works without one, leave it without.
• The inconsistent connector: "as a result" with no cause-and-effect link is worse than nothing: it misrepresents the structure of the reasoning.
• Repetition: the same word three times in ten lines creates a reading tic. Alternate between "so", "that is why" and "as a result".
• The decorative connector: added afterward to turn a tool green. You can hear it, and the reader tunes out.
• Forgetting headings: transitions also matter between sections, not just between sentences.

An example of both

Avoid: "Furthermore, SEO is important. In addition, content needs to be optimized. Moreover, keywords matter." Three connectors, no progression.

Better: "SEO rests on three pillars: content, technical work and authority. Each one calls for a distinct approach. For example, content work starts with choosing topics before choosing keywords." A single connector, and the reasoning moves forward.
