Include a trailing slash when pointing to your website
Omitting the trailing slash on links pointing to your website, whether from external sources or from within your own website, has an adverse impact on speed.
When you visit a URL without the trailing slash, the web server will look for a file with that name. If it doesn’t find a file with that name, it will then treat it as a directory and look for the default file in that directory.
In other words, by omitting the trailing slash, you’re forcing the server to execute an unnecessary 301 redirect. While it may seem instantaneous to you, it does take slightly longer !
