Clickthrough Ratio (CTR) in SEO measures the percentage of users who click on a search result after seeing it on a search engine results page (SERP). It shows how effective a listing is at attracting clicks compared to how many times it was shown.
Synonyms: CTR, Clickthrough Rate, Click Ratio, Click Percentage

Clickthrough Ratio is calculated by dividing the number of clicks a search result receives by the number of times it appears (impressions), then multiplying by 100 to get a percentage. For example, if a page appears 100 times in search results and gets 5 clicks, the CTR is 5%.
A higher CTR means more people find your listing relevant and appealing, which can lead to more traffic to your website. Search engines may also use CTR as a signal to rank pages, so improving your CTR can help boost your position in search results.
Improving CTR involves optimizing your title tags and meta descriptions to make them clear and compelling. Using relevant keywords, adding numbers or questions, and ensuring your snippet matches user intent can encourage more clicks.
What is a good clickthrough ratio in SEO? CTR varies by industry and keyword, but generally, a CTR between 2% and 5% is considered average.
Does a higher CTR improve search rankings? While not the only factor, a higher CTR can positively influence rankings as it signals relevance to search engines.
How is clickthrough ratio different from clickthrough rate? They are often used interchangeably to mean the same metric measuring clicks versus impressions.
