There are thousands of WordPress plugins. Most of them are not worth your time, and a significant number will slow your site down, conflict with each other, or stop being maintained at some point and become a security liability.
This is not a list of every plugin a designer might conceivably need. It is a shorter list of plugins that solve specific problems well, have a reasonable maintenance track record, and are worth knowing about if you run a portfolio or client-facing site on WordPress.
1. WP Rocket
What it does: caching, performance optimisation, and page speed improvement.
WordPress generates pages dynamically: every time someone visits a page, PHP runs, the database is queried, and the HTML is assembled and sent to the browser. For a site with steady traffic, this is unnecessary work. A caching plugin stores a pre-built version of each page and serves that instead, which is considerably faster.
WP Rocket is the most polished caching plugin available for WordPress. It handles page caching, browser caching, file minification (combining and shrinking CSS and JavaScript files), lazy loading of images, and database cleanup, all from a single interface that is straightforward enough that you do not need to understand every setting to get a meaningful speed improvement.
It costs £49 per year for a single site licence, which is not free. The free alternatives, W3 Total Cache and WP Super Cache, both work, but they require more configuration and the interfaces are less intuitive. For a designer who bills for their time and does not want to spend an afternoon tuning a caching plugin, WP Rocket is worth the cost.
One note: if your host provides server-level caching (some do, at the LiteSpeed or Nginx level), check whether a separate caching plugin is redundant before buying. At Angelsites, we can advise on this for your specific setup.
2. Imagify
What it does: automatic image compression and WebP conversion on upload.
Unoptimised images are the most common cause of slow WordPress sites. Imagify compresses images automatically when you upload them, converts them to WebP format for browsers that support it (which is now effectively all of them), and can bulk-process your existing media library.
The free tier covers around 500 images per month, which is sufficient for most designers who are not uploading large volumes regularly. The paid plans remove that limit and add a few additional options, but the free version is genuinely useful rather than a teaser.
The reason Imagify makes this list over other compression plugins is that the setup is straightforward, the compression quality at the default settings is good, and WebP conversion works reliably without requiring additional configuration. ShortPixel is a comparable alternative if you have a reason to prefer it.
3. Yoast SEO
What it does: on-page SEO management, technical SEO basics, and site structure.
Yoast SEO is the most widely installed SEO plugin for WordPress and has been for over a decade. It handles the technical side of SEO that would otherwise require manual editing: meta titles and descriptions, canonical tags, XML sitemaps, Open Graph tags for social sharing, and schema markup. It also gives you a readability and SEO analysis for each page and post, which is useful if SEO is not your primary area of expertise.
The free version covers everything most designers need. The paid version adds features like internal linking suggestions and redirect management, which are useful for larger sites but not essential to start with.
Rank Math is a strong alternative that has gained ground in recent years and is arguably more feature-complete in the free version. Either is a reasonable choice. The reason Yoast is mentioned here rather than Rank Math is that it has a longer track record and is what most clients will already have installed if you are taking over an existing site.
4. Gravity Forms
What it does: contact forms, enquiry forms, and any form more complex than a basic contact page.
WordPress has a built-in comment form and there are several free contact form plugins, Contact Form 7 being the most widely used. For a simple “name, email, message” contact form, these are fine.
For anything more involved, Gravity Forms is worth knowing about. It handles conditional logic (show or hide fields based on earlier answers), multi-page forms, file uploads, calculations, and integrations with payment processors and CRM systems. For a designer who takes on client projects via a detailed brief form, or who builds sites for clients that need anything beyond a basic enquiry form, Gravity Forms handles it without requiring custom development.
It starts at $59 per year for a single site licence. That is a cost to factor in, but for client work where you bill for development time, it saves considerably more than it costs.
WPForms is a comparable alternative with a more beginner-friendly interface. Gravity Forms has more flexibility and is the better choice if you anticipate needing advanced logic or integrations.
5. UpdraftPlus
What it does: automated backups to an external destination.
Your host almost certainly runs backups of their own. You should not rely solely on those backups, for the same reason you do not keep your only copy of a client project file on the client’s server.
UpdraftPlus automates WordPress backups and sends them to an external destination: Google Drive, Dropbox, Amazon S3, OneDrive, or a few others. The free version covers the core functionality. Set it to back up daily or weekly, store to Google Drive, and keep the last four or five copies. Configure it once and it runs without further attention.
For client sites you manage, UpdraftPlus on each site backing up to a dedicated Google Drive folder gives you a clear restore path that does not depend on your host’s backup system. This is worth having regardless of how good your host’s own backups are.
The paid version adds features including remote site management via a central dashboard, which is useful if you are managing many client sites and want a single place to monitor backup status.
A few that did not make the list, and why
Jetpack is installed on a significant number of WordPress sites and does a large number of things: backups, security scanning, performance, social sharing, stats. The breadth is part of the problem. Jetpack is a large plugin that adds overhead to every page load, and most of its individual features are done better by dedicated plugins. Unless you specifically want the convenience of one plugin handling everything, it is worth avoiding.
Elementor and other page builders are useful tools and many designers build with them. They are not on this list because they are design and build tools rather than utility plugins, and whether to use a page builder is a different kind of decision from whether to use a caching plugin. That said, if you are using Elementor, make sure you are on a host with enough PHP memory allocated to run it without issues. 256MB is a reasonable minimum.
Security plugins like Wordfence or Solid Security (formerly iThemes Security) are worth knowing about for client sites that have had problems or operate in higher-risk contexts. For a standard portfolio or small business site on a reputable host, the security basics, strong passwords, two-factor authentication on the admin account, and keeping WordPress and plugins updated, cover most of the realistic risk without needing a dedicated security plugin adding overhead.
The right set of plugins for your site depends on what the site does and how you work. But if you are starting from scratch or auditing an existing WordPress install, these five are reliable, well-maintained, and solve problems that most designers will run into sooner or later.
