A sitelink is a sub-link that appears under a main result in a search engine results page (SERP). It’s a way for search engines to provide quick access to specific pages or sections within a website directly from the search results.
Sitelinks are automatically generated by the search engine based on their assessment of the website’s structure and content, as well as its popularity and user behaviour. When a user searches for a website or brand name, the sitelinks displayed can provide easy access to the most important pages of the website, such as the home page, products, services, about us, contact, etc.
In terms of SEO, having sitelinks for a website can improve its visibility and credibility in the SERP, as well as increase the chances of users clicking through to the site. Sitelinks also help users quickly find the information they’re looking for, which can improve the overall user experience.
