There are a ton of plugins out there to choose from, hundreds of thousands even. Instead of going and doing a bunch of research to figure out which ones to use, I'll show you the 7 plugins I use with every one of my website designs that accomplish most of your client's needs.
This is my all-time favorite plugin. With over 5 million active installs, it is the most popular page builder for WordPress.
I can do it all when it comes to Elementor, and the handoff to the client is incredible. The user interface of the builder makes sense to most clients, so there's less to teach.
I mention Elementor Pro here because it's worth every penny. It allows me to create nav menus, footers, archive pages, WooCommerce pages, and more all from the Elementor editor. It almost makes themes obsolete. There is also a pretty cool feature that allows you to create marketing popups, too.
Hands down, this beats Divi, Bakery Builder, Beaver Builder, and any other builder for me.
Sometimes, a client doesn't need a fully customized build, or you need some inspiration to get things started. I used Envato Elements for hundreds of Elementor template kits. It also free and premium versions.
I personally subscribe to them for premium content since they offer all sorts of digital assets.
I use this plugin to connect all of the WordPress sites I manage using GoDaddy Pro. This allows me to do things like automatic backups, one click updates on every single one of my websites, client reports, and more. Basically, it saves me a ton of time and helps show the work I do for my clients.
WP Rocket is my caching plugin of choice. It is a premium plugin so there is a subscription for it but I believe it's worth it due to the functionality and the support behind it.
They have an unlimited license for $249/year that makese sense as you grow your business.
This plugin helps me optimize my client's images in bulk and convert them to WebP format, which comes with even further image reduction size.
You can test out the plugin here.
Yoast is the most popular SEO plugin and for good reason. They make it easy to optimize a website regardless your skill level.
Your clients are expecting at least some type of SEO to be done with their website, even if just the basics. This plugin can help you do that and wow them at the same time.
No plugin list is complete without something mentioning security. Sucuri is my go to plugin to harden my client's websites.
I typically pair this with their other services like malware removal or firewall since this plugin works great at integrating those services together.
That's my list of plugins I use with almost every one of my website builds. I'd love to know if you have any other preferences in the comments below!
