10 Recommended WordPress Plugins (Based on 100s of Builds).

Radical is a WordPress web agency. Over the years, we’ve built hundreds of WordPress websites for businesses of all shapes and sizes.

We know that the right plugins can make a website faster, more effective and easier to manage.

And the wrong plugins? Well, they have the potential to clash with one another and slow your website down.

If you’re wondering which plugins might be right for your website, take a look at our recommended WordPress plugins — the software we regularly use when building websites for our clients.

These are tools we trust and that we put to use when they’re the right fit for a given project.

Our recommended WordPress plugins for 2026

1. Advanced Custom Fields (ACF) Pro

What it does

This must-have WordPress plugin is really useful for building flexible, bespoke WordPress sites that are still easy for clients to manage.

Imagine you’ve got a property website. You want to display things like price, number of bedrooms, location and a gallery on every property listing. But you don’t want to code or fiddle with page layouts every time.

ACF provides a wide range of fields. So when you go to add your new property, you simply enter information into these fields and your website will display it nicely.

This helps you organise your listings cleanly and logically. And it’s useful for all sorts of pages, including product pages, case studies, service pages and team profiles.

Why we like it

We have lots of clients coming to us wanting to redesign an old website they simply can’t edit themselves.

They’re stuck, having to ask their web developer whenever they want to add a new page because making changes requires coding know-how.

ACF helps us build websites that clients can update with ease. So they never have to wait for a third party to get their site up to date.

They can provide all the information customers need, improving website engagement and conversions in the process.

2. Contact Form 7

What it does

Contact Form 7 has been around for nearly 20 years and it’s a great WordPress plugin for basic, lightweight contact forms.

Features include anti-spam protection and CAPTCHA integration. It’s also easy to customise your forms and add a variety of form fields.

For companies looking to gather basic information, like a customer’s name, email address and message, Contact Form 7 is the best plugin option around.

Why we like it

We use Contact Form 7 when a client wants a basic contact page design and contact form.

We love that it’s lightweight, so it doesn’t slow a website down. We also love that it’s completely free to use, so you don’t have to factor it into website costs.

This plugin is a popular option for B2B websites where getting potential customers to get in touch is the primary conversion goal.

3. Gravity Forms

What it does

Gravity Forms is another of our recommended WordPress plugins and another form-building tool.

It’s great for creating enquiry forms, quote requests, booking forms, application forms and surveys. And it can handle much more complex requirements than Contact Form 7. Stuff like:

• Conditional logic (showing different questions depending on the answers users give)
• Conversational, multi-step forms (great for customer engagement and company branding)
• File uploads (so users can upload documents or images as part of their enquiry)
• Payment collection (integration with payment platforms so you can manage secure transactions straight from your form)

Why we like it

We build lots of websites that are aimed at generating enquiries. Websites where the contact form is an important step in the sales process.

With Gravity Forms, we can tailor forms to capture the exact information a business needs, while giving customers a more personalised and convenient experience.

We also like that form submissions are stored neatly in WordPress. So it’s easy for businesses to track and manage enquiries in one place.

4. WP Rocket

What it does

WP Rocket helps improve website performance by automatically applying a range of speed optimisation techniques.

It caches parts of your website so pages load faster. It optimises CSS and JavaScript files to reduce page size. It can also help with lazy loading (only loading images and videos when they’re about to appear on screen) and removing database clutter.

Why we like it

Website speed is incredibly important.

If your website loads slowly, users become frustrated and leave. If your website loads quickly, they’re much more likely to stick around and explore your content.

Faster load times can also improve your SEO performance. Your site is more likely to show up in search results, which means more organic traffic.

WP Rocket is on our list of recommended WordPress plugins because it helps us create sites that get business results for our clients.

5. Converter for Media

What it does

Chunky image files are one of the usual suspects when it comes to slow site loading times.

The Converter for Media plugin helps you compress images, retaining their quality while minimising their file size as much as possible.

It does this by converting JPEG, PNG and GIF formats (which tend to be on the chunky side) into WebP and AVIF formats (which are lightweight and speedy to load).

Converter for Media allows you to convert your whole media library with just one click, making it a fast and efficient option for image optimisation.

Why we like it

We always tell our clients about the benefits of professional photography. And of an impactful hero section for their website. Beautiful visuals can create an instant connection between a potential customer and your brand.

But those lovely high-resolution images can also weigh a website down. This leads to slow site speeds, which (as we’ve already mentioned) have a negative effect on user experience and your SEO.

We like using Converter for Media because it helps us balance those two priorities — engaging visuals and site performance — without compromising on either.

6. Safe SVG

What it does

SVG files (scalable vector graphics) are used for company logos, website icons and simple graphics because they stay crisp and sharp at any size. Unlike JPEG or PNG files, an SVG won’t look blurry on a large screen or a high-resolution display.

There’s just one problem. WordPress doesn’t allow SVG uploads because SVG files can contain malicious code.

Safe SVG solves this issue by sanitising SVG files on upload. This essential plugin for WordPress strips out any potentially harmful code while allowing the files to be used normally on the site.

Why we like it

Your logo appears across your website (and marketing materials) and it’s a key element of your website branding. Likewise, icons and graphics help to communicate your brand identity and make a connection with website visitors.

We use Safe SVG so that logos and icons render perfectly at every size and on every device, while keeping your website secure.

7. Rank Math SEO

What it does

If you want your website to get found by search engines, the SEO foundations have to be right. Rank Math helps you manage those foundations within WordPress.

It helps with SEO essentials like:

• Page titles and descriptions
• XML sitemaps
• Schema markup
• Search appearance settings
• On-page SEO checks

There’s a free version that comes with extensive tools and paid versions with additional, premium features.

Why we like it

Our clients often come to us with websites that are missing basic SEO foundations. No meta descriptions. Schema set up incorrectly or not at all. Pages that aren’t optimised for target keywords.

Getting these basics in order is one of the first things we tackle during a rebuild — and Rank Math makes that process quick and easy.

Rank Math provides the SEO tools we need when building your website and you need when managing it. And while it won’t get you to the top of Google on its own, used correctly, it can help your site get found and ranked by search engines — which means more website visitors.

8. Redirection

What it does

When pages on a website move, change URL or get removed entirely, browsers and search engines need to be told where to go instead.

Without a redirect, you get a broken link and visitors end up at a 404 error page. This is bad for your user experience and for SEO.

The Redirection plugin helps you manage 301 redirects (permanent redirects that tell search engines a page has moved). It also logs 404 errors so you can find and fix broken links.

It’s particularly useful during redesigns, site migrations and when restructuring how a website is organised. But it also comes in handy for everyday website maintenance.

Why we like it

Website redesigns are exciting. But they can also create a real headache if old pages are removed without a plan.

Redirection is another of our recommended WordPress plugins and we use it on every rebuild project we take on. Before we launch a new site, we map every relevant URL from the old site and set up the appropriate redirects.

This helps us protect SEO during a redesign, so the new site can hit the ground running, showing up in search results and bringing in traffic.

9. WP Migrate

What it does

During a website project, a website moves between three primary stages:

• Local. This is the development stage where the new site is stored on a developer’s computer. We write code, design layouts and build features without affecting the live site.
• Staging. This is a version of the website hosted on a server that mimics the live site. At this stage, we (and our clients) review and test the website before making it public.
• Live. The fully-functional site goes live and is available to everyone on the internet.

WP Migrate helps us move your WordPress website between these different environments, moving the database, files and media in a way that keeps everything working correctly.

Why we like it

Moving a website between these different stages is part and parcel of web design and development. And WP Migrate is one of our recommended WordPress plugins because it supports this migration cleanly and reliably.

The site arrives in its new environment looking and behaving exactly as it should, which means less time spent on debugging and more time spent building your site.

This plugin also allows us to keep clients in the loop. You can test your site in the staging environment, providing feedback which we can then action.

After thorough testing, by both you and us, we can be confident that when we show your site to the world, it’ll be the best it can be.

10. Query Monitor

What it does

Query Monitor is a developer tool that sits behind the scenes. It gives developers a detailed view of what’s happening under the bonnet of a WordPress website.

It monitors and reports on database queries, PHP errors, HTTP requests and plugin and theme interactions. And it highlights issues that affect website functionality and performance.

Why we like it

Query Monitor is a really useful website quality assurance tool. It helps to uncover website problems that aren’t always visible from the front-end.

We use Query Monitor throughout the build process and particularly during testing, where it helps us catch issues before a website goes live.

We’ve also used it extensively when diagnosing performance issues on existing websites — it can quickly surface exactly where time and resources are being wasted.

Ultimately, this must-have plugin for WordPress helps us diagnose site issues faster and build better-performing websites.

What we look for in a WordPress plugin

There are thousands of WordPress plugins to choose from. Some are excellent. Some are poorly built or poorly maintained. When deciding which to use, here are the things we consider:

Does it solve a real problem? Every plugin should have a clear purpose. We avoid shiny object syndrome and more for the sake of more.

Is it regularly updated? Outdated plugins can create website security and compatibility issues. We only use plugins that have been updated recently, ideally in the last few months.

Does it have good reviews? And how many people are actually using it? We look at the WordPress plugin directory to see ratings, active installation counts and user reviews.

Will it slow the site down? Every plugin is another thing for your website to load. Some are lightweight. Others make a significant dent in website performance. We strike a careful balance, with website speed as a priority.

Could it be built better another way? Sometimes a custom solution is better than adding another plugin. We always consider whether bespoke code will serve the website better than an off-the-shelf tool.

A few top tips when using our recommended WordPress plugins

If you’re managing your own WordPress site, these habits will save you time and stress.

• Keep plugins updated. Plugin updates often include security patches as well as new features. And an outdated plugin is an open door to security threats. Check your WordPress dashboard regularly and apply updates (ideally in a staging environment first) before rolling out to your live site.
• Remove plugins you no longer use. Even deactivated plugins take up space on your website and can still create security risks. Anything you’re not using can go.
• Choose quality over quantity. It’s always a better idea to find plugins that cover multiple bases. You don’t want a separate plugin for every website task, as it will slow your website down.
• Remember that plugins don’t always play nicely together. Plugin conflicts can cause your site to behave in unexpected ways. If something breaks on your site after a plugin update, deactivate plugins one by one to identify the culprit.
• Get professional help if you’re unsure. Plugin management can be complicated. If you don’t feel confident managing your plugin stack, opt for a website maintenance plan. A professional web team can take care of updates, security monitoring and conflict checking.

The right plugins used in the right way. Think Radical.

Plugins are one of WordPress’s biggest strengths. They allow websites to be extended and customised without building everything from scratch.

That keeps costs down, speeds up development and puts powerful functionality within reach of even the smallest business.

But plugins are only as good as the decisions behind them. The wrong choices — too many, poorly maintained, badly configured or carelessly combined — can slow a website down and create security risks.

At Radical, we use these recommended WordPress plugins carefully as part of a wider website strategy. We choose tools that help businesses manage their websites, improve performance and achieve their goals.

If you’re thinking about a new WordPress website or your current site has become difficult to manage, get in touch with the Radical team and we’ll be happy to help.

FAQs

How many plugins should a WordPress website have?

There’s no magic number. One website might have several plugins, while another might only need one or two. The important thing is that each plugin serves a purpose and doesn’t compromise website performance.

Do plugins slow down a WordPress website?

Yes, they can. Poorly built plugins or having too many unnecessary plugins can affect performance. That’s why we carefully consider which plugins we need to install.

Are free WordPress plugins safe to use?

Many free plugins are excellent — Contact Form 7 and Query Monitor are both free and used widely by professional developers.

The question isn’t whether a plugin is free or paid, but whether it’s well-maintained, regularly updated and comes from a reputable source. Always check the last update date and the active installation count before adding a plugin to your site.

What’s the difference between a plugin and a theme?

A WordPress theme controls the visual appearance of your website — the layout, fonts, colours and design. A plugin adds specific functionality — for example, a contact form, a performance tool or an SEO manager.

The two work alongside each other. Your theme defines how things look. Your plugins determine what your website can do, both on the front end and behind the scenes.
