How page speed affect SEO
Page speed can be described as either “page load time” (the time it takes to fully display the content on a specific page) or “time to first byte” (how long it takes for your browser to receive the first byte of information from the webserver).
Google has indicated that site speed (and as a result, page speed) is one of the signals used by its algorithm to rank pages. And research has shown that Google might be specifically measuring time to the first byte when it considers page speed. In addition, a slow page speed means that search engines can crawl fewer pages using their allocated crawl budget, and this could negatively affect your indexation.
Page speed is also important to user experience. Pages with a longer load time tend to have higher bounce rates (people leaving the site without engaging) and lower average time on page. Longer load times have also been shown to negatively affect conversions.
How To Increase Your Page Speed
You should also ensure any images uploaded to your site are compressed as much as possible without losing quality. You can do this in programs like Photoshop or free online software like tinyjpg.com. For more information on image optimization, see page 14.
You can clean up your code and compress images all day long. But if you spend $4.99/month on hosting, your site isn’t going to load quickly. That’s because you’re sharing a server with a million other websites.
As a general rule: when it comes to hosting, you get what you pay for.
So if you’re serious about improving your site’s loading speed, it might be time to upgrade to a premium host or dedicated server.
