Ways to speed up your site

Use fast hosting, a fast DNS (‘domain name system’) provider

Minimise ‘HTTP requests - keep the use of scripts and plugins to a minimum, use one CSS stylesheet (the code which is used to tell a website browser how to display your website) instead of multiple CSS stylesheets or inline CSS

Ensure your image files are as small as possible (without being too pixelated)

Compress your web pages (this can be done using a tool called GZIP), Minify your site’s code - rid of any unnecessary spaces, line breaks or indentation in your HTML, CSS and Javascript (see Google’s Minify Resources page for help with this)


Negative SEO Impact for slow sites

If your pages are slow to load, Google will figure it out and will categorize your website as poor user experience, therefore suffering in terms of organic visibility. If you haven't done it yet, I strongly advise you to use the PageSpeed Insights tool: Google PageSpeed Insights


Relevant Tools and Resources

Lighthouse

Please note that Lighthouse belongs to Google and their advice is (a bit too) specific to Google Chrome, so for instance it will advise you to use new image formats which may not be usable and rendered on other browser such as Firefox or Safari.
