WordPress has a built-in search feature which allows a site using self-hosted WordPress to search local pages and posts, and then display the results on the site. What if you want to use an external search engine like DuckDuckGo to do this instead?
Most people have pictures on their website. If you don’t have any pictures, you probably should! When these pictures are original works you don’t want other people using them. Another reason to add a watermark is if you want your logo on your pictures so people can identify your brand.
Don’t let your website be a victim of content theft!
Stop other websites from using your website content with their message (overlay) over top.
Some websites offer a “service” to create their own call to action over top of any website. Why is this a problem? If some other person is using your content with their own call to action or ads on top it can appear that they created the content.
They are getting the benefit from your content. Some would consider that content theft. At best it’s pretty shady.
