WordPress best practices
Always update your plugins when an update becomes available. Most updates are security updates and if you keep them up to date your website is less prone to hacking.
On the update link on the left, you will find that the updates button will have the number of updates available click on it and update all and that is all.
Create content often on your website to keep your site relevant and indexed better on Google. Write articles, news or share things related to your blog contents.
