The 15 best WordPress plugins for SEO and security

WordPress plugins are a great way to edit your website according to your individual needs. With WordPress plugins, you have a lot of freedom, but you can quickly lose track of everything.

To help you find the right plugins for you, we have compiled the best WordPress plugins compiled. Here you will find general plugins for the design, but also the WordPress SEO plugins and the WordPress GDPR plugins for your legal security.

This overview is a general list and is intended to give you some orientation. Which plugins are ultimately right for you depends on your wishes, target groups and also the reach targets you want to achieve with your website.

General information about WordPress plugins

Plugins have advantages and disadvantages. Which ones outweigh the others depends on your goals. Plugins allow you to design your site beyond the basic functions. WordPress plugins usually specialize in their own functions or subject areas, such as SEO marketing. Such WordPress SEO plugins support you in the search engine optimization of your content so that your website can be found faster on Google.

With WordPress plugins, you select the functions you need. If all plugins were automatically included in the basic function, your website would be too slow and overloaded. We therefore always advise our customers to limit their choice of plugins to the bare essentials so as not to negatively impact the pagespeed of their website.

You can now find around 60,000 plugins in the WordPress directory - and only those that are WordPress plugins can be found there. You can search for specific plugins so that you can limit your selection directly to the plugins you need.

Another advantage of WordPress plugins is that you can optimize your site even without programming knowledge. The plugins do the programming work for you, so you don't need to know how to edit the theme codes or design the page with CSS yourself. This saves you time that you can invest in your content. You'll find a wide selection of plugins for every theme in the directory, so you're sure to find what you're looking for. To make it even easier for you to choose the right plugin, you can take a look at the ratings from the WordPress community and the number of plugin users.

WordPress plugins and security

For all their advantages, WordPress plugins also offer a certain potential for danger. You should be aware of this before you start working with the plugins.

This is because not all WordPress plugins are written by professional programmers. This can mean that the plugins suddenly stop working, for example due to a lack of updates by the programmer, or contain malicious code.

Depending on the plugin, this increases the risk of being hacked. If the plugins contain security vulnerabilities, they offer an attack surface for your website. Faulty code or even targeted malicious code can be used by cyber criminals to steal or copy your data or make your website unusable. For example, if the WordPress DGUV plugin is faulty, this can lead to legal consequences.

Our 4 WordPress plugins tips for a secure website that you can implement immediately:

• Less is more. Do without unnecessary plugins. Alternatively, you can program functions yourself or reduce them to the bare essentials. For a good SEO ranking, you don't always need an SEO plugin in WordPress, but can also optimize the site manually.
• Only download plugins from reputable sources. Unfortunately, the plugins in the directory are not checked, but you can tell from the ratings whether they are reputable.
• Update your plugins regularly so that they are always up to date.
• Do not test your plugins on the live website. Create staging pages (i.e. a clone of your website on a subdomain) where you can try out the plugins at your leisure. Only install them on the official site once they have passed the test. Take a look at our tips for a good software test. 

How WordPress plugins influence page speed

One important point is the pagespeed of your website. WordPress plugins can slow down the loading time of your WordPress website under certain circumstances, which has a negative impact on your Google ranking and therefore your findability.

As most plugins access a database, they may cause a lot of hits. These accesses cost loading time and slow down your site.

As loading time is an important factor in ranking, this can cost you one or more places - and therefore perhaps page 5 instead of page 1 - on Google.

For this reason, you should test how the plugin affects your performance before using it.

If you don't want to do without certain WordPress plugins, you can prevent unnecessary database access by deactivating the functions that you don't need for your site.

Plugins that you no longer need are best deleted. Simply deactivating them will still cost you loading time, storage space and security.

Based on our many years of experience, we have tested many WordPress plugins and found them to be good, helpful and secure. Our recommendations for the best WordPress plugins can be found categorized by subject area in the following overview!

SEO plugins support you in the search engine optimization of your website. SEO plugins are suitable for both SEO beginners and SEO professionals.

With the plugins, you can optimize your texts while writing and know for sure that your site meets the SEO criteria.

1. yoast SEO

This plugin has been on the market for a long time and is still one of the most popular WordPress SEO plugins for search engine optimization. Yoast SEO is available in free and paid versions.

Pagespeed/Performance Plugins

The so-called page speed or loading speed is important for the search engine ranking. You also lose website visitors due to slow loading times of your website. Users do not wait long on the page before they leave it again.

For a good search engine ranking and a high level of user-friendliness, your website should load quickly. Images, superfluous source code or unnecessary settings slow down your site. Webshop operators who have to load a lot of images on their site are particularly familiar with this problem. One trick is lazy loading, for example.

In addition to your own website settings, the right WordPress plugins for good page speed. This is because the wrong WordPress plugins are more likely to make your loading times worse than better. As pagespeed experts, we have tested various caching and performance plugins that will make your website load even faster. These are our absolute heartfelt recommendations:

Since large images in particular have a strong negative impact on the page speed of your website, this image optimization can improve your loading time considerably. Smush also offers many other features, such as lazy loading. Lazy loading means that the images only load once you have scrolled down to them. This prevents you from loading images that you don't need. Many users do not scroll to the bottom of the page, but remain at the top of the page.

This plugin therefore saves loading time and is compatible with almost all browsers.
