Also, if I change the favicon, will it be reindexed by Google, and how long will it take for the changes to take effect?
Changing your website logo generally won’t negatively impact your SEO. Google primarily focuses on content and technical factors like website speed and mobile responsiveness when ranking websites.
However, changing your favicon, which is the small icon displayed in the browser tab, can lead to reindexing. Google will recognize the new favicon as a change and may re-index your website, which can take anywhere from a few hours to a few days.
It’s important to note that Google’s indexing process is not instantaneous and can vary depending on factors such as the size of your website and the overall traffic it receives.
