The frequency of updating meta tags depends on how frequently the content of your website changes. For websites with frequently updated content, regular updates to meta tags may be necessary. For example, news websites should update meta tags as new stories are added. For more static pages, less frequent updates may suffice. For instance, product pages may only need updates if there are changes to the products. In general, it is advisable to review and update meta tags at least annually to ensure they remain accurate and relevant.
