Website Maintenance Checklist: What Should You Test On Your Website Regularly

A website should not be checked only when something breaks.

Most website problems start quietly.

A contact form stops sending enquiries.
A page becomes slow on mobile.
A tracking tag stops firing.
A cookie banner blocks conversions.
A plugin update changes a layout.
A checkout step fails.
A blog post loses its SEO title.
A domain or SSL renewal is missed.

The website may still look fine, but it is no longer working properly.

This is why website maintenance should not be treated as “just updates”.

It should be a regular testing process.

This guide shows what to test, how to test it, which tools to use, what problems to look for, and how to fix them.

Quick Website Maintenance Checklist

Use this as your regular testing list.

You do not need to use every tool every day.

Use the right tool for the right check.

1. Test Website Speed

Website speed affects almost everything.

It affects SEO.
It affects paid ads.
It affects form submissions.
It affects ecommerce checkout.
It affects how much users trust the business.

A slow website is not just a technical issue. It is a sales issue.

What to test

Test these pages first:

• homepage
• main service pages
• contact page
• quote page
• campaign landing pages
• product pages
• checkout pages
• top blog pages

Do not test only the homepage. Many websites have a fast homepage and slow service or product pages.

Tool 1: Google PageSpeed Insights

Use: Google PageSpeed Insights

How to use it:

1. Open the tool.
2. Enter your website URL.
3. Run the test.
4. Check both mobile and desktop.
5. Look at the “Opportunities” and “Diagnostics” sections.
6. Repeat the test for your most important pages.

Focus on:

• LCP: how quickly the main content loads
• INP: how quickly the page responds when someone clicks or taps
• CLS: whether the page layout jumps while loading
• image size
• JavaScript issues
• unused code
• server response time

Tool 2: GTmetrix

Use: GTmetrix

GTmetrix is useful because it gives a more visual breakdown of how the page loads.

Use it to check:

• page size
• number of requests
• slow files
• waterfall loading order
• large images
• third-party scripts
• fonts
• tracking scripts
• videos
• sliders

Common issue now

Many websites are not slow because of one big problem.

They are slow because of too many small things:

• oversized images
• too many plugins
• chat widgets
• tracking scripts
• cookie banners
• embedded videos
• sliders
• page builders
• unused JavaScript

INP issues are also becoming more common. The page may load, but it reacts slowly when users click buttons, open menus or submit forms.

How to fix it

Start with the easy wins:

• compress large images
• replace PNGs with WebP where possible
• remove unused plugins
• remove scripts you do not need
• delay non-essential JavaScript
• reduce sliders and animations
• use caching
• use a CDN
• improve hosting if server response is slow

If speed problems are caused by old code, poor hosting or a heavy theme, maintenance alone may not be enough.

See Rozzario Web Development Services or Website Design Services.

2. Test the Website Technology Stack

Before fixing a website, understand what it is built with.

Many business owners do not know:

• whether the site is WordPress, Shopify, Webflow or custom
• what analytics tools are installed
• what ad pixels are installed
• what CMS or ecommerce platform is being used
• what plugins or third-party scripts are running
• what email, CRM or chat tools are connected

This matters because every tool adds maintenance risk.

Tool: BuiltWith

Use: BuiltWith

How to use it:

1. Enter your website URL.
2. Review the detected technologies.
3. Look for CMS, analytics, advertising, hosting, ecommerce and tracking tools.
4. Make a list of tools you still use.
5. Remove or review tools you no longer use.

BuiltWith can help identify:

• CMS
• ecommerce platform
• analytics tools
• ad pixels
• live chat tools
• CRM scripts
• email marketing tools
• hosting/CDN signals
• JavaScript libraries

Common issue now

Old tools stay on websites for years.

A website may still have:

• old Facebook Pixel code
• unused Hotjar scripts
• old Google Analytics code
• duplicate GA4 tags
• unused chat widgets
• old plugin scripts
• multiple page builders
• outdated tracking tools

These can slow the website and confuse tracking.

How to fix it

Create a simple “website tool register”.

For each tool, write:

• tool name
• what it does
• who owns it
• whether it is still needed
• where it is installed
• whether it affects tracking or speed

Remove what you do not use.

Keep tracking scripts inside Google Tag Manager where possible so they are easier to manage.

3. Test Domain, DNS, Hosting and SSL

Some website problems are not inside the website.

They come from domain, DNS, hosting or SSL issues.

These problems can affect:

• website loading
• email delivery
• tracking
• landing pages
• payment pages
• domain reputation
• security warnings

Tool 1: WHOIS Lookup

Use: WHOIS Lookup

Use it to check:

• domain registrar
• domain registration status
• expiry date
• nameservers
• ownership-related information where available

Tool 2: Ping.eu DNS Lookup

Use: Ping.eu DNS Lookup

Use it to check:

• A records
• CNAME records
• MX records
• TXT records
• nameserver response
• DNS propagation issues

Tool 3: SSL Labs

Use: SSL Labs SSL Test

Use it to check:

• SSL certificate setup
• certificate expiry
• HTTPS configuration
• server security grade
• mixed configuration issues

What to test

Check:

• domain expiry date
• hosting renewal date
• nameservers
• SSL certificate
• DNS records
• email records
• Cloudflare access
• hosting control panel access
• domain registrar login
• billing email address

Common issue now

A common problem is that nobody knows who controls the domain.

The website agency may have registered it.
An old employee may own the login.
The billing email may go to an unused inbox.
DNS may have been changed during a migration.
Email records may be incomplete.

This can cause website downtime, email failure or slow support during emergencies.

How to fix it

Keep a domain and hosting record.

Include:

• registrar
• hosting provider
• renewal date
• admin email
• DNS provider
• Cloudflare access
• billing owner
• backup contact

Do not leave domain ownership unclear.

If your website setup is messy or spread across too many providers, get it reviewed properly.

See Rozzario Website Maintenance Services.

4. Test Uptime and Response Time

You cannot manually watch your website all day.

Use uptime monitoring.

A website can go down for many reasons:

• hosting issue
• plugin conflict
• server overload
• DNS issue
• SSL issue
• failed update
• traffic spike
• payment failure
• database error

Tool: UptimeRobot

Use: UptimeRobot

How to use it:

1. Create a monitor for your homepage.
2. Add monitors for key landing pages if needed.
3. Set alerts to email, SMS or Slack.
4. Monitor response time, not only downtime.
5. Add SSL and domain expiry monitoring if available.

What to test

Monitor:

• homepage
• checkout page
• main landing page
• client portal
• booking page
• important form page

Common issue now

Many websites do not go fully offline. They become slow or unstable.

The site loads sometimes, fails sometimes, or returns errors for certain users.

This is harder to notice manually.

How to fix it

Set uptime alerts.

If downtime repeats, check:

• hosting resources
• error logs
• plugin conflicts
• server CPU/memory
• CDN issues
• database errors
• traffic spikes
• cron jobs
• security blocks

If a website regularly goes down, the maintenance plan should include hosting review, not just website updates.

5. Test Forms, WhatsApp, Phone Links and Lead Flow

This is where many websites lose money.

A form can look fine but fail in the background.

A WhatsApp button can open the wrong number.
A phone link can fail on mobile.
A quote form can send leads to spam.
A CRM integration can disconnect.
A thank-you page can stop loading.
A tracking event can stop firing.

What to test

Test:

• contact form
• quote form
• booking form
• newsletter form
• popup form
• download form
• checkout form
• WhatsApp link
• phone link
• email link
• calendar link
• live chat

How to test it properly

Do not just click the form.

Submit a real test enquiry.

Then check:

1. Did the form submit?
2. Did the thank-you message or page appear?
3. Did the user receive confirmation?
4. Did the business receive the email?
5. Did the lead enter CRM?
6. Did the correct source appear?
7. Did GA4 record the event?
8. Did Google Ads or Meta record the conversion if it should?

Test from mobile.

Test using mobile data.

Test with a Gmail address and a business email address.

Tools to use

Use:

• your website form plugin
• CRM logs
• email inbox
• spam folder
• GA4 DebugView
• Google Tag Manager Preview
• Google Tag Assistant
• HubSpot or CRM test contact
• SMTP tools or logs

Common issue now

Email deliverability is a major issue.

Forms may submit successfully, but emails do not arrive because:

• SMTP is not configured
• SPF/DKIM/DMARC records are missing
• the recipient mailbox changed
• the CRM integration expired
• the form notification goes to spam
• CAPTCHA blocks users
• plugin updates changed form behaviour

How to fix it

Set up proper SMTP.

Check SPF, DKIM and DMARC records.

Send form enquiries to more than one place:

• sales inbox
• CRM
• backup email
• Google Sheet if needed

Do not rely on one inbox.

6. Test Tracking and Conversion Events

Before judging SEO, Google Ads or Meta Ads, check tracking.

Bad tracking creates bad decisions.

You may think a campaign failed when tracking is broken.
You may think a campaign worked when duplicate conversions are firing.
You may think SEO is weak when leads are not attributed properly.

What to test

Test:

• GA4 page views
• GA4 form submit events
• Google Ads conversion events
• Meta Pixel events
• TikTok Pixel events
• LinkedIn Insight Tag
• phone click tracking
• WhatsApp click tracking
• email click tracking
• thank-you page views
• ecommerce events
• UTM parameters
• CRM lead source

Tool 1: Google Tag Assistant

Use: Google Tag Assistant

How to use it:

1. Open Tag Assistant.
2. Connect your website.
3. Open the page you want to test.
4. Submit a form or click a tracked button.
5. Check whether the right tags fired.
6. Check if any tags failed or fired twice.

Tool 2: Google Tag Manager Preview

Use it inside your Google Tag Manager account.

Use it to check:

• tags
• triggers
• variables
• data layer events
• conversion events
• consent behaviour

Tool 3: GA4 DebugView

Use it inside Google Analytics 4.

Use it to check whether events are appearing in real time.

Common issue now

Consent banners and privacy settings often break tracking.

A tag may fire before consent.
A tag may not fire after consent.
A cookie banner may block all analytics.
A conversion event may fire twice.
A thank-you page may count refreshes as new leads.

How to fix it

Keep tracking inside GTM where possible.

Name events clearly.

For example:

• form_submit_contact
• click_whatsapp
• click_phone
• quote_request
• purchase
• book_consultation

Test tags after:

• website updates
• cookie banner changes
• landing page changes
• CRM changes
• ad account changes
• form plugin updates

If you run campaigns, see Rozzario Performance Marketing Services, Google Ads Management Services and Meta Ads Management Services.

7. Test SEO Health and Indexing

SEO maintenance is not only about publishing blogs.

It is also about protecting the pages that already rank.

A small technical issue can quietly reduce traffic.

What to test

Check:

• page titles
• meta descriptions
• H1 headings
• internal links
• broken links
• redirects
• canonical tags
• sitemap
• robots.txt
• noindex tags
• schema markup
• image alt text
• 404 errors
• pages not indexed
• duplicate pages

Tool 1: Google Search Console

Use: Google Search Console

Check:

• Pages report
• Sitemaps
• URL Inspection
• Search performance
• Core Web Vitals
• manual actions
• indexing issues

Use URL Inspection for important pages.

Ask:

• is the page indexed?
• can Google crawl it?
• is the canonical correct?
• was it recently crawled?
• are there indexing problems?

Tool 2: Screaming Frog

Use: Screaming Frog SEO Spider

Use it to crawl your website and find:

• broken links
• missing titles
• duplicate titles
• long titles
• missing meta descriptions
• redirect chains
• 404 pages
• noindex pages
• canonical issues
• large images
• missing H1s
• duplicate H1s

The free version is enough for many smaller websites.

Tool 3: Rich Results Test

Use: Google Rich Results Test

Use it to test structured data such as:

• FAQ schema
• product schema
• review schema
• local business schema
• breadcrumb schema

Common issue now

A common SEO issue is accidental de-indexing.

This can happen after:

• staging site migration
• plugin update
• redesign
• CMS migration
• page duplication
• wrong canonical tags
• old redirect rules
• AI-generated thin pages
• poor internal linking

How to fix it

Keep a list of your most important URLs.

After any update or migration, check:

• title
• H1
• meta description
• index status
• canonical
• internal links
• redirect status
• schema

For SEO support, see Rozzario SEO Agency, SEO Content Writing Services, AI SEO Services and Generative Engine Optimisation Services.

8. Test Keywords, Search Demand and Content Freshness

Website maintenance should also include content checks.

Not every update is technical.

Sometimes the issue is that the website is answering old questions.

What to test

Check:

• outdated service pages
• old pricing
• old offers
• expired promotions
• outdated screenshots
• broken portfolio links
• old case studies
• weak FAQs
• blog posts losing traffic
• pages not matching current search behaviour

Tool 1: Google Trends

Use: Google Trends

Use it to check:

• whether a topic is rising or falling
• seasonal interest
• regional interest
• related queries
• comparison between terms

Example:

Compare:

• website maintenance
• website support
• WordPress maintenance
• Shopify maintenance

This helps you understand what people call the service.

Tool 2: Ahrefs Keyword Generator

Use: Ahrefs Keyword Generator

Use it to find:

• keyword ideas
• question keywords
• long-tail search terms
• related topics
• local search phrases

Search examples:

• website maintenance checklist
• website maintenance services
• WordPress maintenance services
• Shopify maintenance services
• website support services
• website speed optimisation
• website audit services

Tool 3: Ahrefs Website Authority Checker

Use: Ahrefs Website Authority Checker

Use it to check:

• Domain Rating
• backlink strength
• competitor authority
• link gap signals

Do not obsess over authority scores.

Use them as a benchmark, not the final truth.

Common issue now

Many businesses publish content but do not refresh it.

Old blogs stay live even when:

• screenshots are outdated
• advice has changed
• internal links are broken
• search intent has shifted
• competitors have better answers
• AI search tools need clearer structured answers

How to fix it

Every quarter, update the pages that matter.

Improve:

• headings
• FAQs
• internal links
• examples
• images
• CTAs
• schema
• clarity
• direct answers

For content improvements, see Rozzario SEO Content Writing Services.

9. Test UX and User Behaviour

A page can pass technical tests and still fail users.

This is why website maintenance should include simple UX checks.

What to test

Check:

• can users understand the page quickly?
• is the main CTA visible?
• is the menu clear?
• is the page too crowded?
• are buttons easy to tap?
• are forms too long?
• are trust signals visible?
• are users scrolling but not clicking?
• are users clicking non-clickable elements?

Tools to use

Use:

• Microsoft Clarity
• Hotjar
• BrowserStack
• Chrome DevTools mobile view

Microsoft Clarity and Hotjar can show heatmaps and session recordings.

Use them to see:

• where users click
• where users stop
• where users rage-click
• whether users ignore CTAs
• whether users abandon forms

Common issue now

Many websites are designed for appearance, not action.

They look good but hide the next step.

Users should not have to guess what to do.

How to fix it

Make the page easier.

Use:

• one clear main CTA
• shorter forms
• stronger headings
• better spacing
• fewer distractions
• clearer service sections
• visible trust points
• direct internal links

If the whole website journey feels unclear, see Rozzario Website Design Services.

10. Test Security, Updates and Backups

Security checks should be routine.

Do not wait until the site is hacked.

What to test

Check:

• WordPress core updates
• plugin updates
• theme updates
• Shopify app issues
• unused plugins
• unused themes
• admin users
• password strength
• two-factor authentication
• malware alerts
• firewall logs
• suspicious redirects
• spam submissions
• SSL certificate
• backups

Tools to use

Use:

• Wordfence for WordPress
• Sucuri SiteCheck
• Google Safe Browsing Site Status
• SSL Labs
• hosting backup tools
• UpdraftPlus for WordPress backups

Common issue now

Old plugins and old admin users are still one of the biggest risks.

Websites often have:

• unused admin accounts
• abandoned plugins
• outdated themes
• weak passwords
• no two-factor authentication
• backups stored only on the same server

How to fix it

Every month:

• remove unused users
• delete unused plugins
• update carefully
• keep backups offsite
• test restore process
• enable two-factor authentication
• use strong unique passwords
• review security alerts

A backup is only useful if it can be restored.

Ask:

• where is the backup stored?
• how often does it run?
• does it include files and database?
• who can restore it?
• when was the last restore test?

For maintenance support, see Rozzario Website Maintenance Services.

11. Test Ecommerce and Checkout

If you sell online, test the buying journey regularly.

This applies to Shopify, WooCommerce and custom ecommerce websites.

What to test

Check:

• product pages
• collection pages
• search
• filters
• cart
• checkout
• payment methods
• shipping options
• discount codes
• tax settings
• order confirmation email
• abandoned cart email
• product images
• reviews
• return policy links
• Google Merchant Centre feed
• ecommerce tracking

How to test

Place a test order if possible.

Use mobile.

Check:

1. Can the product be added to cart?
2. Do variants work?
3. Does checkout load?
4. Do payment options appear?
5. Does the discount code work?
6. Does shipping calculate correctly?
7. Does the order confirmation email arrive?
8. Does the order appear in the store backend?
9. Does GA4 record the purchase?
10. Does the ad platform record the conversion?

Tools to use

Use:

• Shopify test order
• WooCommerce test order
• Stripe test mode
• PayPal sandbox
• GA4 ecommerce reports
• Google Merchant Centre
• Meta Events Manager
• Google Tag Assistant

Common issue now

Checkout issues often appear after app, plugin, shipping or payment changes.

A store can look normal but still lose sales because:

• Apple Pay does not show
• shipping rules are wrong
• discount codes do not apply
• product variants are broken
• checkout tracking is missing
• product feed is disapproved
• abandoned cart emails are not firing

How to fix it

Test checkout after every major store change.

For Shopify support, see Rozzario Shopify Store Development Services and Ecommerce Store Development Services.
