15 Common WordPress Installation Mistakes You Should Avoid

Installing WordPress takes only a few minutes, but avoiding common WordPress installation mistakes can save you hours of troubleshooting later.

A wrong setting during the initial setup can affect your website’s SEO, security, performance, backups and even whether Google can properly index your pages.

In this guide, we’ll cover 15 common WordPress installation mistakes, explain why they matter, and show you what to do instead.

1. Choosing Hosting Only Because It Is Cheap

Hosting is one of the first decisions you make when creating a WordPress website.

It is also an area where many website owners try to save as much money as possible.

There is nothing wrong with affordable hosting. The problem starts when price becomes the only factor in the decision.

Poor hosting can result in:

• Slow website loading
• Frequent downtime
• Limited server resources
• Poor support
• Difficult backups
• Outdated PHP versions
• Problems when your traffic increases

Before choosing a host, check whether it supports current PHP versions, SSL, backups, caching and enough resources for your type of website.

A small business website and a busy WooCommerce store don’t necessarily need the same hosting environment.

Better approach: Choose hosting based on your website requirements, not simply the cheapest available plan.

2. Installing WordPress in the Wrong Directory

This is surprisingly common.

Suppose your domain is:

example.com

But during installation, WordPress accidentally gets installed inside:

example.com/wordpress/

or:

example.com/wp/

Now your website URLs contain an unnecessary folder.

This often happens when using automatic WordPress installers and accepting all the default settings without checking them.

Before clicking Install, always verify the installation directory.

If WordPress is meant to run on your main domain, the installation directory should normally be empty.

---

3. Using “admin” as Your Administrator Username

Using admin as your WordPress username makes an attacker’s job slightly easier.

They already know one part of the login credentials and only need to guess the password.

Instead of:

admin

use a username that isn’t obvious.

Also remember that changing the username alone doesn’t secure WordPress. You should still use a strong password, keep WordPress updated and protect the login area appropriately.

---

4. Using a Weak Password

A password such as:

admin123

wordpress123

companyname123

might be easy to remember, but it is also easy to guess.

Your WordPress administrator account has access to almost everything on the website, so protecting it should be a priority.

Use a long, unique password containing a combination of characters, and don’t reuse the same password you use for email, hosting or other accounts.

For important websites, enabling two-factor authentication is also worth considering.

---

5. Not Setting Up HTTPS From the Beginning

Your website should load using:

https://example.com

instead of:

http://example.com

Most hosting providers now offer free SSL certificates, so there is usually little reason to launch a normal WordPress website without HTTPS.

Installing SSL later can create additional work because old HTTP URLs may already exist inside content, images or database records.

This can lead to mixed-content warnings and unnecessary redirects.

Better approach: Configure SSL and HTTPS before you start adding significant content to the website.

---

6. Forgetting to Change the Permalink Structure

A fresh WordPress installation may not always have the URL structure you want.

Go to:

Settings → Permalinks

For most content-focused websites, a clean structure such as:

example.com/sample-post/

is easier to understand than URLs containing unnecessary parameters.

Your exact permalink structure should depend on the website, but the important point is to decide it before publishing dozens or hundreds of pages.

Changing URL structures later may require redirects to prevent broken links and loss of existing search visibility.

---

7. Forgetting to Check Search Engine Visibility

This is one of the WordPress mistakes that can directly affect SEO.

During development, developers often enable:

Settings → Reading → Discourage search engines from indexing this site

That’s perfectly reasonable while a website is under development.

The problem happens when the website goes live and nobody turns it off.

You may launch the website, submit it to Google and start publishing content — while WordPress is still telling search engines that you don’t want the website indexed.

Always include this setting in your website launch checklist.

After launch, also verify the site’s actual robots directives and indexing status rather than relying only on the checkbox.

---

8. Installing Too Many Plugins

One of the best things about WordPress is its plugin ecosystem.

Need a contact form? There’s a plugin.

Need SEO features? There’s a plugin.

Need a slider? Another plugin.

Need one small CSS change?

Sometimes people install another plugin for that too.

Before long, a simple website can have 30 or 40 plugins installed.

The number itself isn’t the only issue. A well-developed plugin can be better than a badly developed plugin with only a few features.

The real problems are unnecessary plugins, duplicated functionality, poor-quality code and plugins that are no longer maintained.

Before installing a plugin, ask:

Do I actually need this?

If WordPress, your theme or an existing plugin already provides the functionality, another plugin may not be necessary.

---

9. Using Nulled Themes or Plugins

A premium WordPress theme or plugin normally costs far less than recovering a compromised website.

Downloading nulled versions of commercial themes and plugins from unknown websites can expose your site to modified code, malware, spam links, backdoors or other security problems.

You also lose legitimate updates and developer support.

Use plugins and themes from trusted sources and purchase commercial products from their official developers or authorized marketplaces.

Saving a small amount today isn’t worth creating a major security problem tomorrow.

---

10. Keeping Plugins and Themes You Don’t Use

A new WordPress installation may include default themes or plugins that you don’t need.

Developers also often install several plugins while testing different solutions and then simply deactivate the ones they don’t choose.

If you know you’re not going to use something, remove it.

Unused software creates unnecessary maintenance and can become a security concern if it is forgotten and left outdated.

Keep the website clean.

---

11. Ignoring PHP and Plugin Compatibility

A WordPress plugin may install successfully and still cause problems later.

Before installing important plugins or themes, check:

• WordPress compatibility
• PHP requirements
• Recent updates
• Developer support
• WooCommerce compatibility, if applicable
• Known conflicts

This is particularly important when working on older websites.

Don’t blindly upgrade PHP or install a major plugin directly on a production website without checking compatibility.

For established websites, test significant changes on a staging environment first.

---

12. Not Configuring Backups

Many website owners think about backups only after something goes wrong.

That’s too late.

A website can break because of:

• A failed update
• Human error
• Malware
• Server problems
• Plugin conflicts
• Database issues

You should have a backup strategy before the website becomes important.

At minimum, make sure both the WordPress files and database are backed up.

Even more importantly, don’t just assume backups work.

Periodically confirm that the backups are actually being created and can be restored.

A backup you cannot restore isn’t much of a backup.

---

13. Ignoring Basic WordPress Security

WordPress itself is actively maintained, but your website’s security also depends on how you configure and maintain it.

Basic precautions include:

• Strong passwords
• Limited administrator accounts
• Regular updates
• Trusted plugins and themes
• HTTPS
• Backups
• Login protection
• Appropriate file permissions

Avoid blindly applying every “WordPress security trick” you find online.

Security should be practical and layered rather than a collection of random code snippets copied into .htaccess or functions.php.

---

14. Forgetting Basic WordPress Settings

After installing WordPress, spend a few minutes reviewing:

Settings → General

Check your:

• Site title
• Tagline
• Administration email
• Site language
• Timezone
• Date format
• Time format

The timezone setting is particularly easy to overlook.

An incorrect timezone can affect scheduled posts, WooCommerce orders, logs and other time-sensitive functionality.

Also remove the default “Hello world!” post, sample page and unnecessary demo content before launch.

These are small details, but they make the installation clean from the beginning.

---

15. Launching Without Checking SEO Basics

Installing an SEO plugin does not automatically mean your website is optimized for search engines.

Before launching, check the basics.

Make sure important pages can be indexed, your XML sitemap works, canonical URLs are correct, redirects behave properly and your site doesn’t accidentally contain noindex directives left over from development.

You should also check:

• Page titles
• Meta descriptions
• Heading structure
• Internal links
• Image alt text where appropriate
• Mobile usability
• Website speed
• Broken links
• Sitemap
• robots.txt

After launch, connect the website with Google Search Console so you can monitor indexing and identify technical search issues.

---

Bonus Mistake: Editing Everything Directly on the Live Website

This isn’t technically an installation mistake, but it’s a habit worth avoiding from the beginning.

Making every major change directly on the production website can eventually cause trouble.

Imagine updating a plugin on a WooCommerce website and suddenly discovering that checkout no longer works.

Whenever possible, use a staging or development environment for major updates, custom development and potentially risky changes.

Test first.

Deploy second.

A Simple WordPress Installation Checklist

Before you start building your website, check these essentials:

• Choose suitable WordPress hosting
• Install WordPress in the correct directory
• Configure HTTPS
• Create a secure administrator account
• Use a strong unique password
• Configure permalinks
• Set the correct timezone
• Remove unnecessary default content
• Install only required plugins
• Use trusted themes and plugins
• Configure automatic backups
• Review basic security
• Check search engine visibility
• Configure SEO essentials
• Test the website before launch

Taking an extra 15–30 minutes during the initial WordPress setup can save hours of troubleshooting later.

Final Thoughts

WordPress makes creating a website relatively easy, but the default installation should only be considered the starting point.

The decisions you make during the first setup can affect your website’s security, performance, SEO and maintainability later.

You don’t need to make WordPress unnecessarily complicated.

Start with a clean installation, use only the tools you actually need, keep everything updated, maintain reliable backups and test your website properly before making it public.

If you’re building your first WordPress website, bookmark this checklist and go through it once before launch.

And if you already have a WordPress website, it may be worth checking these points anyway.

You might find a setting that has been overlooked since the day your website was installed.
