Updating Your WordPress Site
It’s strongly advised that you keep up to date with the latest version of WordPress, all plugins and themes installed on your site to avoid problems such as bugs and security vulnerabilities. To make your life easier, WordPress issues regular updates to increase its functionality, fix bugs and deal with security concerns.
Most plugin developers such as ourselves at Semperplugins.com also issue regular updates for our plugins. We recommend you install these updates as soon as they become available.
Always start by updating WordPress itself, then your themes, and then your plugins. You should do so in order to minimize the risk of any conflicts that may affect the performance of your website, particularly if your site is large and complex. In fact, apply your updates one at a time so you can quickly trace the source of any problem, if one should occur.
You need to check that your website is functioning correctly after every update. Always double check your site’s functionality and speed across all devices and browsers. In particular, all the links and navigational tools on your website should work and direct all users (regardless of device and browser) to the right places. This is especially important for SEO, as crawlers need to be able to access all content on your website.
Your database needs to be cleaned out every few months in order for it to keep running quickly and efficiently. The more content, plugins, themes and comments are added to your site, the more complex and heavy your database will be. This could eventually cause it to slow down; and over time, you may find that it takes way longer to retrieve data within your database.
There are various plugins that can help keep your database clean. A good one is WP-Sweep, which keeps your information in an ordered format and reduces the clutter. There are various other plugins available, like WP-DBManager and WP-Optimize. Choose one that best suits your needs and is easy for you to use.
Google Analytics & Webmaster Tools
Use these tools to keep an eye on your site’s downtime; to monitor which pages are loading more slowly; and to see which links may be broken. Those are all common problems that can later become major issues.
