Permalinks are the URLs that are always permanent on your website. While the content on a page might change, the URL will always stay the same. Permalinks are important for SEO because having URLs that reflect exactly what the page is about is helpful for both the user and the search engine. Additionally, Google looks at the URL as part of its ranking factor, so having the URL that accurately reflects the content of the page and contains keywords can possibly influence SEO. Lastly, when someone copies and pastes a URL to share on social media or elsewhere, having a clean URL helps external sites format the link. By having a clear idea of what the link is about, other users are more likely to click on it.
