Import/export your metadata from CSV
SEOPress makes work easy for you by enabling importation of your metadata from CSV files. This capability, however, is only available on SEOPress Pro.
Metadata that you can import from your CSV file include meta description, title tag, canonical URL, Facebook open graph tags, Meta Robots, redirection, primary category, Twitter tags, and target keywords.
To import the metadata, go to SEO, Tools, Data section and then click on ‘Run the Importer’. You can also access the importer from Tools > Import > SEO metadata (CSV). Upload the CSV file, click Next and select fields from the CSV file to map against posts – or ignore during import. Click on ‘Run the Importer’.
White-label SEO plugin
You can white-label SEO services with this plugin, even on the free version. This is great for agencies and developers because the plugin allows them to put their own branding on SEOPress tools they use on their SEO clients.
The Cheapest Premium plan
At $49 per year, SEOPress gives you the cheapest premium plan among the SEO plugins reviewed in this article. With the yearly subscription, you can use the plugin on unlimited sites. With several sites on other plugins like Yoast and AIOSEO, you will have to pay more.
Complementary SEO WordPress Plugins
There are several complementary tools that can be used along with these plugins to increase efficiencies in your SEO efforts.
Schema Pro makes it possible for you to add rich snippets on your website. Rich snippets make your site stand out from search results by showing star ratings below a product review, a review, and video or image next to the description.
Some WordPress SEO plugins we have covered like AIOSEO have this feature inbuilt, adding structured rich snippets data to your site.
The inbuilt schema features on some SEO plugins may be limited in their functionality, and that’s why Schema Pro might be a good addition to your SEO tool set. Schema Pro allows you to use it alongside your favorite SEO plugin.
Schema Pro will map your SEO plugin’s data to Schema Pro fields. Because of the attractive nature of rich snippets, proper implementation can see an increase in your site’s click through rate. Bloggers, review websites, and small businesses looking to solidify their presence on SERPs should use rich snippets.
A redirection tool is key in ensuring that you do not lose traffic to a deleted web page. Most plugins we have covered in the article have an in-built redirection feature or redirection manager.
A redirection tool simply redirects a specific inactive page to a different live page. If you intentionally or accidentally delete a page that ranks high for a specific keyword on Google, redirecting it to a new page means that you will maintain the page traffic.
Implementing a 301 redirect tells Google and other search engines to look at another page. As an SEO strategy, 301 redirects prevent loss of traffic. By specifying the URL of the new page, all traffic will be redirected to the new page.
In addition to helping you implement 301 redirect, redirection tools also help you stay on top of 404 errors. The redirection tool is an important tool for any marketer, developer, or any site owner that is redesigning their website.
Monsterinsights is a great tool for tracking SEO analytics. It will help you track and measure your SEO performance. The MonsterInsights WordPress plugin brings Google Analytics to your WordPress dashboard.
With GA right on your dashboard, you do not need to manually install code on your site to start tracking various activities and data. You will be able to see how people find and visit your site, as well as access content reports with details of the pages with most visitors.
MonsterInsights presents the analytics in a simple way that is easy to comprehend. With this tool, you do not have to visit Google Analytics to view your analytics. The tool makes it possible to multitask without completely leaving your dashboard.
This tool is ideal for developers, bloggers, marketers, and other stakeholders who want to optimize their website for conversions. It is also a time saver considering you’re presented with analytics right on your dashboard.
Site Kit is the official WordPress plugin by Google. The plugin makes it easy to configure and set up key Google products like Google Analytics, Google Search Console, AdSense, and Google PageSpeed Insights.
This is a useful plugin for agencies and developers because it’s a one-stop solution for deploying, managing, and getting insights on key Google tools to make clients’ sites successful on the web.
It is important to note that Site Kit is not a replacement for the Google products mentioned like Google Analytics and search console. Rather, the plugin provides authoritative and up-to-date insights from multiple Google products directly on your WordPress dashboard.
Through the help of Site Kit, you should first integrate products like Google Analytics with your website before you can use the plugin to get insights from inside your WP dashboard.
Other Google products that can be integrated and accessed on your dashboard through Site Kit include Google Tag manager and Google Optimize.
WP Supercache is a WordPress plugin that generates HTML files from dynamic WordPress blogs. Your web server will then serve the generated HTML file instead of processing the heavier PHP scripts. The result is that you will have fast loading page speeds.
This is a free plugin with over 2 million active installs. With Google making page speeds an important ranking factor, we can understand why this plugin is popular among WordPress users. The cache plugin skips many steps behind the scenes to ensure your visors enjoy great speeds and site performance.
A site that loads quickly encourages users to come back again. Regular site traffic is an indicator to Google that you are trusted in your specific domain or businesses, further boosting your SEO.
Although the WP Supercache plugin may look intimidating due the technical language used and its complex setup options, you can set it up within a few minutes with proper guidance.
A broken link is a link that leads to a 404 page. You do not want your site visitors to encounter this error everytime they visit a specific page. But you can only fix this problem if you know that you have broken links and can locate them. This is where the broken link checker comes in.
Manually going through your site to find these broken links can be time consuming. Furthermore, it is possible that you may miss out on some broken links. But with the broken link checker, all broken links are revealed within minutes.
Once these broken links are revealed, you can replace them with working links. The alternative is to completely remove the broken links.
Keeping the plugin always active may have a negative impact on your site’s performance because of the plugin's constant scanning functionality. The best practice is to regularly – not always – keep the broken link checker active so that it updates you whenever a new broken link is detected.
A site without broken links creates a good impression on Google, and this can help boost your SEO.
The SEMrush Writing Assistant is an on-page optimization tool available on SEMrush. This tool gives you real-time analysis and suggestions as you write your blogs or articles on WordPress.
This tool assesses your competitor’s SEO trends and provides you with feedback on improvements based on this analysis. The aim is to ensure you produce quality and better-optimized content than your competitors.
SEMrush, along with Ahrefs and Moz, are among the most popular SEO tools. The SEMrush Writing Assistant tool is available as a plugin. The tool also integrates with text editors like Google Docs, making it possible to optimize your content away from your WordPress dashboard. You can then upload the optimized content on your WP post.
The tool will give you clues on what your competitors rank for and why. The goal is to achieve a specific score that marks the threshold of meeting the minimum SEO requirements to be at par or outperform your top 10 competitors. Users should always balance producing quality content for the reader and meeting these scores.
What is a SEO WordPress Plugin?
SEO plugins are tools that help your website rank higher on search engines. Plugins make it possible to achieve your SEO goals by performing tasks like content optimization, adding links, keyword research, and much more.
Just merely installing an SEO plugin on your WordPress site does not give you a guarantee that your site will rank high. You must know how to use the plugin to meet specific SEO KPIs. These plugins provide you with guidance and tips on how to improve your content. In addition, most of the SEO plugins offer tutorials and user guides on how to use the tools and get the best out of them.

How to Choose the Best SEO Plugin?
WordPress comes optimized for SEO. For example, WordPress enables you to add headings, titles, meta descriptions, customize URLs, tags, alt texts, and much more.
SEO experts would not need an SEO plugin to be reminded to perform these SEO tasks. Still, having an SEO plugin makes work easier, even for experienced SEO and digital marketing experts. Furthermore, some SEO functions like SEO analysis are not native to the CMS, and only a third-party tool can help users perform the analysis.
So how do you choose the best SEO WordPress plugin? The following factors are crucial when shopping for an SEO plugin.
Number of SEO Features
Since you are looking for a plugin purely for SEO purposes, it’s important that the plugin can perform many of the key SEO tasks. The more SEO features, the better. This means you’ll be able to handle all your SEO needs with a single plugin.
Having multiple SEO plugins with overlapping functions on a single website can cause problems. In addition to bloating and slowing your website, the plugins can create confusion. Sticking with a single plugin for a website is the best practice.
Although different websites may have different SEO needs, some functions are fundamental for all sites. Depending on the specific aspects of SEO you want to address, ensure the SEO plugin has the following capabilities:
- Keyword SEO
- SERP SEO
- On-page SEO
- Local SEO
- Video SEO
- Social Media SEO
- Google AMP SEO
A good SEO plugin should give you access to analytics that showcase your SEO performance. This will allow you to measure your SEO performance and make adjustments to improve on areas that are falling behind.
Tracking SEO metrics by yourself can be challenging and time-consuming. With a good SEO plugin, relevant metrics like organic traffic, organic keywords, and referring domains should be visible.
These metrics will help you make informed decisions. If something major happens, you’ll know instantly when it happens, and why it happened, and you also get recommendations on improvements.
Ease of Use
Assuming you are not an SEO expert, you’ll prefer a plugin that is easy to use. Plugins like SEO Press and AIOSEO rank high in ease of use in the WordPress SEO community. These platforms have install wizards that guide you through the setup process.
The support team from the plugin company can also help you maneuver through various issues you encounter while using the tool. However, reliable support services are mostly available on paid plugins or premium plans for plugins that include the free option.
Free versus Paid Plugins
Most of the SEO plugins reviewed in this article have free and paid versions. Before paying for a tool, you can try the free version and assess the plugin's potential.
Most free versions of the plugins, however, have limited functionalities compared to the paid versions. For example, you’ll have limited customer support with a free version.
Although small sites might find free versions of a plugin like Yoast or SEOPress to be enough, large websites have higher and more complex SEO needs. These complex SEO requirements may necessitate upgrading to a paid version of the SEO plugin.
How to Install a Free SEO Plugin?
The steps followed in installing an SEO plugin are not different from installing any other type of plugin. If you have ever installed a plugin on a WordPress website, this process should be a breeze.
Like any other plugin, you can install an SEO plugin either automatically or manually. We will use the Yoast SEO plugin as an example, but the process should be similar to all other plugins.
- The first step is to get access to your WordPress dashboard
- Click on ‘Plugins’ on the menu available on the left-hand side and then click on ‘Add New’.
- Type ‘Yoast SEO’ on the search box. Type the name of any other SEO plugin that you want to install.
- You will get results with the SEO plugin of interest included. Go to the specific SEO plugin interested in the search results and click ‘Install Now'. The installation process will start.
- Once the installation process is complete, click the ‘Activate’ button.
You have installed and activated the SEO plugin. Go ahead and start configuring the plugin to suit your SEO needs.
- To manually install the free Yoast SEO plugin, you have to first download the plugin from their website.
- To download the free version, click on the ‘Free version available’ link that is below the premium CTA. A file named wordpress-seo.19.7.zip will be downloaded and saved on your computer.
- Go to your WordPress dashboard, select ‘Plugins’, and click on ‘Add New’.
- Click on the ‘Upload Plugin’ tab at the top of the page
- Upload the zip file. Activate the plugin

SEO is an important part of modern online marketing efforts. Every business running an online platform should incorporate SEO as part of its marketing strategies. And if the website runs on WordPress, then an SEO plugin is a crucial tool to have.
There are many SEO plugins to choose from. Some are free, while others offer premium features and services that must be paid for. Your choice of plugin will depend on the size of your site and business, the features you’re looking for, ease of use, and budget.
A good SEO plugin guides you through the SEO process and also acts as a reminder on what actions you should take. The plugin could be the difference between appearing on the first page of Google and entirely missing out on any appearance on search engines.
A WordPress site does not need SEO plugins because the CMS comes optimized for SEO. The plugins are only used to make work easier and for automation.
Rank Math is the lightest SEO plugin. The plugin has 415 files and 29.6k lines of code, with an overall file size of 8.5MB. For comparison purposes, Yoast has around 1075 files, 95k lines of code, and overall file size of 26.4MB.
One SEO plugin loaded with all essential features is enough to do the work. However, you can add extra tools to complement the plugin with additional features like performance and schema.
Yoast SEO is the best SEO plugin for a blogger. This is because of its on-page insights feature that makes it easy to optimize content.
WordPress sites need plugins to achieve specific goals. However, having many plugins can slow down the website. The key is to ensure your website has the optimum number of plugins not to compromise site performance.
No, it is not harmful. In fact, it is possible to transfer all data you’ve gathered from one plugin to another plugin you’re migrating to.
