WordPress SiteCHAPTER 01: Types: Staticor Dynamic Before we dive into the optimizations, it’s important first to understand that not allWordPress sites are the same. This is why a lot of users have problems, as you can’tgo about tackling every issue the same way. We always give WordPress sitesa classification: static or dynamic. So let’s first explore the differences between thesetwo types of sites. Mostly Static Sites Static would typically include sites such as blogs, small business sites, lower volume newssites, personal, photography, etc. By static, we mean that the data on these WordPresssites isnot changing very often(perhaps a couple of times a day). Even most of our Kinstasite would be considered a static website. This becomes incredibly important as many of the requests can be served directly fromcache on the server at lightning-fast speeds! Don’t worry; we’ll dive into the topicof caching in length further below. This means they will have fewer database calls and notas many resources will be needed to achieve google performance. Highly Dynamic Sites On the flip side, we have highly dynamic sites. These include sites such as eCommerce(WooCommerce or Easy Digital Downloads), community, membership, forums (bbPressor BuddyPress) and learning management systems (LMS). By dynamic, we mean that thedata on these WordPress sites isfrequently changing(server transactions are taking placeevery few minutes or even every second). This means that not all requests to the servercan be served directly from cache and require additional server resources and databasequeries. These sites also typically have alarge number of concurrent visitors and sessions.On an informational or corporate WordPress site which is mostly static, a visitor mightstay for five or 10 minutes until they find what they need (and this is a high number, usuallybounce rates are much higher). On dynamic sites, you have the opposite happening.Visitors typically come to the site to engage with something or someone. If they’re goingthrough an online course, it’s not unusual for them to stay for hours. “You can see where this is going. The concurrent visitors connected to your WordPress hostadds up fast. To make it worse, you then have a large number of concurrent visitors on topof an “uncacheable content” problem. You can't treat all WordPress sites the same whenit comes to performance. Static and highly dynamicsites are two very different beasts. ChooseCHAPTER 02: High-PerformanceWordPress Hosting A WordPress host is a company that stores all of your website’s data.
