Imagine spending hours building a beautiful website, only to find out that visitors have been getting error messages the whole time. Frustrating, right? The truth is, most website owners have no idea their site is broken until a customer complains or they lose a big chunk of traffic.
That is where a website checker comes in. Think of it as a health checkup for your site. It scans your website and tells you exactly what is working, what is broken, and what needs your attention. No technical background required.
Whether you are running a small blog, an online store, or a business website, keeping tabs on your site’s performance is a must. The good news is that you do not need to be a developer to do it. There are some really simple tools out there that make the whole process easy and beginner friendly.
In this post, we are going to walk you through a list of the best ways to check if your website is actually working the way it should. Let’s dive in!
What Does a Website Check Actually Cover?
If your website loads when you type the URL into your own browser, that feels like a pass. It is not. You are testing from a cached device, on a familiar connection, in a location close to your server. Real visitors arrive from different devices, different browsers, different countries, and with zero cached history. Search engine crawlers do not experience your site the way you do at all.
A proper website check covers seven distinct areas: performance and load speed, basic SEO signals, broken links and crawl errors, HTTPS and security status, uptime and availability, mobile usability, and accessibility. According to Dotcom-Monitor, website checking encompasses everything from uptime monitoring to broken link detection as separate operational concerns, not a single pass/fail result.
The important thing to understand is that each category can fail independently. A site can score well on performance and still have a broken contact form. It can rank in search results and still be serving unencrypted HTTP to mobile visitors despite having a certificate installed. The W3C WAI tools list covers accessibility evaluation alone across multiple distinct testing methods, which shows how much depth sits inside just one of these seven categories.
Large subscription platforms bundle all of these checks into agency-grade dashboards built for teams managing dozens of client sites. For a single business site, that level of complexity is unnecessary. Free, purpose-built tools cover every category without the cost or the learning curve.
This guide works through each category as a separate step. Pick one, run the check, fix what you find, then move to the next.
Performance and Page Speed
Speed is one of the most measurable ways your website either earns or loses visitors, and Google has made its expectations very clear through three Core Web Vitals metrics. Largest Contentful Paint (LCP) measures how quickly your main content loads on screen. Interaction to Next Paint (INP) measures how fast your page responds when someone clicks or taps something. Cumulative Layout Shift (CLS) measures visual stability, specifically whether elements jump around while the page is loading. All three directly influence your search rankings in 2026, not just your user experience scores.
Google PageSpeed Insights is the natural first stop, and it is completely free. Paste your URL in, and it runs two types of checks simultaneously: real-world field data collected from Chrome users over the past 28 days, and a simulated lab test that returns a score between 0 and 100. You get separate scores for mobile and desktop, which matters because mobile scores are almost always lower due to simulated slower network conditions. The tool also surfaces prioritised recommendations, so you know exactly what to fix first rather than guessing.
GTmetrix works brilliantly alongside PageSpeed Insights because it shows you a full waterfall chart of every file your page loads, including its size and how long it took. This makes it easy to spot a 4MB image or a third-party script holding everything else up.
For a practical benchmark, aim for an LCP under 2.5 seconds, a CLS score below 0.1, and a PageSpeed mobile score above 70. These are not official Google cutoffs, but they represent a competitive floor for small business sites.
The most common culprits on SMB sites are uncompressed images uploaded straight from a phone camera, outdated plugins loading unminified JavaScript, and Google Fonts calls that block the page from rendering visible content until the font files finish downloading.
SEO Basics: What Search Engines Actually See
Speed tells part of the story, but what search engines actually see when they crawl your site is a separate conversation entirely. Publishing a page does not guarantee Google will find it, index it, or ever show it in search results. Each of those is a separate hurdle, and a basic search engine fundamentals check will confirm how many of your pages are actually making it through.
Google Search Console is the non-negotiable starting point. It is free, requires site verification (a quick process using an HTML tag, DNS record, or your Google Analytics connection), and gives you direct data straight from Google about your specific property. No paid tool can replicate that. Once you are inside, three things need your attention first: confirm your XML sitemap is submitted and error-free, check that your most important pages are actually indexed rather than accidentally blocked by a robots.txt rule or a noindex tag, and look for any Core Web Vitals failures flagged across your pages. A robots.txt block stops Google from crawling a page entirely; a noindex tag lets Google visit the page but tells it not to include it in results. Both cause the same symptom (invisible pages) but need different fixes.
Ahrefs Webmaster Tools adds a useful free layer on top. Once you verify your site, you get backlink reporting plus a site audit that surfaces missing title tags, duplicate meta descriptions, broken internal links, and thin content. Think of it as Search Console’s complement rather than its replacement.
SE Ranking’s free on-page checker lets you analyse individual URLs without a full subscription, which is handy for spot-checking a key landing page before a campaign goes live.
For a practical pass/fail benchmark, run every page against this checklist: a unique title tag between 50 and 60 characters, a unique meta description under 155 characters, exactly one H1, and at least one internal link pointing to that page from somewhere else on your site. Getting these basics right is still the foundation, even as AI-generated search results change what happens after a ranking is earned.
Broken Links and Crawl Errors
Even after your metadata and speed are sorted, there is still a surprisingly common issue quietly working against your site: broken links. A broken internal link is one that points to a page on your own site that no longer exists, perhaps because it was deleted, renamed, or moved during a redesign. When a visitor or a search engine crawler follows that link, they hit a 404 error. For visitors, it is a dead end that erodes trust. For crawlers, it wastes what is called “crawl budget,” meaning Google spends time hitting error pages instead of finding and indexing the content you actually want ranked. According to Lucky Orange, 42.5% of websites have broken internal links, often not through neglect, but simply because sites evolve over time.
The most accessible tool for catching these is Screaming Frog SEO Spider. The free version crawls up to 500 URLs, which covers most small business sites comfortably. It mimics how Google crawls your site, listing every URL it finds along with its HTTP status code, title tag, and the links pointing to it. Once your crawl finishes, filter the results by status code 404 to isolate broken pages. Then click the “Inlinks” tab on any broken URL to see exactly which pages are linking to it, so you can update those links or set up a redirect.
While you are in there, look out for redirect chains too. That is where a URL redirects to a second URL, which then redirects again. These chains slow down page load time and weaken link equity, and they are especially common on sites that have been migrated or redesigned. Screaming Frog flags them as 3xx chains and they are straightforward to clean up once identified.
For a useful second opinion, check Google Search Console. Under Indexing, the Pages report surfaces 404s and redirect errors that Google discovered during its own crawl, often catching issues Screaming Frog misses because Google has a long memory for URLs that once existed.
Security and HTTPS Status
Security is one of those website health areas that looks fine on the surface until it very much is not. Here is what to check and how to check it.
Every site in 2026 should be serving all pages over HTTPS, full stop. Starting with Chrome 154 in October 2026, Google is enabling “Always Use Secure Connections” by default for all users, meaning Chrome will prompt visitors before they load any site that does not support HTTPS. That friction alone can kill conversions. On top of the user experience hit, Google uses HTTPS as a ranking signal, so an HTTP-only or mixed-content site carries both a trust penalty and a visibility cost at the same time.
SSL Labs’ free SSL Test at ssllabs.com grades your certificate configuration from A+ to F. It flags expired certificates, weak cipher suites, and mixed-content issues, which is where things get sneaky. A page can be served over HTTPS and still be marked insecure if a single image or script loads over plain HTTP. Mixed content is one of the most common post-migration oversights and one that a manual eyeball check will miss completely.
Google Safe Browsing protects over five billion devices daily and will flag your domain if it has been compromised for malware, phishing, or unwanted software. The unsettling part is that site owners often have no idea their site has been serving malicious content to visitors. You can run a free check via the Google Transparency Report in under a minute.
For WordPress sites, the free tiers of Wordfence or Sucuri SiteCheck scan for known malware signatures, blacklist status across major security databases, and outdated plugins carrying known vulnerabilities.
Finally, do the quick manual check: open your site in Chrome, click the lock icon, and confirm the certificate is valid, issued to your domain, and not expiring within 30 days. SSL certificate validity periods are shrinking to 200 days in 2026, which increases renewal frequency and, with it, the risk of a quiet auto-renewal failure going unnoticed.
Uptime Monitoring: Is Your Site Actually Available?
Most site owners find out their website is down the same way: a customer mentions it. By that point, the site may have been offline for hours, with every visitor during that window landing on an error page instead of your business. There are no sales happening, no enquiries coming in, and depending on how long the outage runs, search engine crawlers may log errors against your site too. The good news is that independent uptime monitoring is free, takes minutes to set up, and removes the guesswork entirely.
UptimeRobot is the most practical starting point for small business owners. The free tier checks your site every five minutes from multiple global locations and sends an immediate email or SMS alert the moment it detects a failure. The free plan supports up to 50 monitors, which is far more than most small business sites will ever need. Because checks run from multiple locations before an alert fires, you also avoid false alarms triggered by a single regional blip.
One thing worth doing beyond a basic check is monitoring your most important pages individually. Your homepage returning a healthy status does not mean your contact form, booking page, or checkout is actually working. Set up separate monitors for each of those critical URLs so you know exactly which part of your site has a problem, not just that something is wrong.
Better Uptime offers a comparable free tier with 10 monitors, 30-second check intervals, and public status pages included. A public status page is genuinely useful if your clients expect transparency about service availability.
Finally, that 99.9% uptime guarantee from your hosting provider sounds solid, but it mathematically allows around 8.7 hours of downtime per year. Independent monitoring gives you timestamped incident data you actually control, rather than a contractual promise that is difficult to verify or enforce.
Mobile Usability and Accessibility
Here is something most site owners miss: Google does not judge your website by how it looks on your desktop monitor. Since rolling out mobile-first indexing, Google primarily uses the mobile version of your site to evaluate and rank your content. If your layout breaks on a small screen, your text shrinks to illegible sizes, or your buttons overlap on a phone, that is the version Google is forming its opinion on. Fixing mobile issues is not a cosmetic task; it is a direct input into your search ranking.
Google has folded its mobile usability checking into two free tools worth knowing. The standalone Mobile-Friendly Test has been deprecated, but Google Search Console now includes a Mobile Usability report that flags issues across your whole site, including text too small to read, clickable elements placed too close together, and content wider than the screen viewport. Google Lighthouse, built directly into Chrome DevTools, runs a combined audit covering performance, accessibility, SEO, and best practices in a single report. Open Chrome, right-click your page, select Inspect, then navigate to the Lighthouse tab. Running it on your three most important pages takes under ten minutes and gives you a clear cross-category snapshot without signing up for anything.
For accessibility specifically, the WAVE Evaluation Tool is a free Chrome extension with over 600,000 users that checks pages against WCAG standards, flagging missing image alt text, poor colour contrast, empty form labels, and missing language declarations. If you prefer not to install an extension, the free online accessibility checker at Silktide offers quick WCAG and ADA checks directly in your browser.
For Australian businesses, this goes beyond good practice. Under the Disability Discrimination Act 1992, inaccessible websites can constitute unlawful discrimination, and the Australian Human Rights Commission has issued advisory notes reinforcing this. Accessibility is both an ethical responsibility and a genuine legal consideration worth taking seriously.
What to Do With Your Results: A Simple Triage Framework
Running a website checker gives you a list of problems. Sometimes a very long list. The instinct is to tackle everything at once, but that approach tends to lead to burnout, missed priorities, and the most important issues getting buried under minor ones. A simple three-tier framework helps you work through findings without losing your mind.
Tier 1: Critical (Fix Within 24 Hours)
These are issues where your site is broken, insecure, or being actively penalised. Stop what you are doing and fix these first. Examples include an expired SSL certificate (browsers will label your site “Not Secure” and visitors will leave immediately), pages returning 404 errors with no redirect in place, your site being flagged by Google Safe Browsing for malware or deceptive content, server errors returning 500 status codes, or your site being completely unindexed in Google Search Console. Each of these either breaks the experience entirely or costs you trust with both users and search engines.
Tier 2: Important (Fix Within Two Weeks)
These issues are not stopping the site from loading, but they are quietly costing you visitors and conversions. Mobile usability failures on key landing pages, Core Web Vitals failing across the board, missing title tags on indexed pages, broken contact or booking forms, and HTTP mixed-content warnings all belong here. A broken booking form, for example, is a UX problem and a revenue problem at the same time.
Tier 3: Low Priority (Schedule, Don’t Rush)
Minor accessibility contrast issues on non-critical pages, redirect chains that technically work but are inefficient, and thin-content pages not currently ranking for anything can all wait. They are worth fixing eventually, just not this week.
Write It Down
Once you have sorted your findings into tiers, put everything into a simple spreadsheet with five columns: issue, severity, URL affected, recommended fix, and owner. Even if you run a one-person business, a written list beats a mental one. A mental list expands and contracts based on whatever you noticed last. A spreadsheet stays honest.
When a Website Checker Is Not Enough
A website checker is a diagnostic tool, not a repair tool. It tells you what is wrong, but it does not touch a single line of code. For a lot of the issues it surfaces, the fix is not a settings change or a quick content edit. It requires a developer who can get into the codebase and actually resolve the underlying problem.
Some findings fall into this category more than others. Core Web Vitals failures tied to how your server renders pages cannot be fixed by adjusting an image or tweaking a title tag. Security vulnerabilities in outdated dependencies need someone who understands what those dependencies do and how to update them safely without breaking other things. Broken functionality caused by an API change or an expired third-party integration will not resolve itself. Accessibility failures baked into a theme or component library are structural problems, not content problems, and automated tools cannot patch them at the source.
There is also the question of timing. Running a website check once gives you a snapshot. Running one regularly, as part of an ongoing maintenance rhythm, is what actually keeps a site healthy. Sites degrade quietly. Plugins update independently of each other. Third-party scripts change behaviour. Content accumulates in ways that affect performance. What passed a check six months ago may not pass one today.
This is the model Pixeldev’s ongoing maintenance service is built around: regular health checks, proactive issue resolution, and a development team that already knows your codebase. That last part matters more than it sounds. When something breaks, the difference between a team starting from scratch and a team that built your site is measured in hours, not days.
The gap between launching a site and maintaining it is where most site health problems originate. Launching is a milestone. Maintaining is what keeps that milestone from quietly degrading into a liability.
Keep Checking, Keep Improving
A healthy website is not something you fix once and forget. Problems accumulate quietly over time, and research suggests the average site carries well over 100 technical issues affecting its search performance. The good news is that the tools to catch those problems are largely free, and most of them take less than an afternoon to learn.
If you only do three things after reading this guide, make them a Google PageSpeed Insights test, a Google Search Console review, and a Screaming Frog crawl. Those three checks cover the widest surface area of common small-business site problems at little to no cost. Between them, you will surface slow pages, indexing gaps, broken links, missing metadata, and Core Web Vitals failures — the issues most likely to be costing you traffic and leads right now.
Add UptimeRobot to your homepage and any critical pages today, before you need it. The free setup takes about five minutes, and it will alert you the moment your site goes down. That early warning pays for itself the first time it catches an outage before a client or customer does.
If your checks turn up issues that need a developer to fix, or if you would simply rather hand off the whole job to someone you trust, that is exactly what Pixeldev’s operate and maintenance services are designed for. They work with small teams and growing businesses who want ongoing site health managed as part of a long-term partnership, not a one-off job.
Your action for this week: block two hours, run every check in this guide, and sort your findings using the three-tier framework. Most sites surface two or three critical fixes that have been quietly working against them. Now you have the tools to find them.
Conclusion
Your website is often the first impression people have of your business, so making sure it actually works is non-negotiable. Here are the key takeaways to remember:
- A website checker acts as a health monitor for your site, catching problems before your visitors do
- Regular checks help you stay on top of broken links, slow load times, and errors
- You do not need technical skills to get started; most tools are beginner friendly
- Catching issues early saves you traffic, customers, and revenue
The good news is that you now have everything you need to take action. Pick one tool from this list, run your first check today, and see exactly where your site stands. Small improvements made consistently add up to big results over time. Your website works hard for you, so return the favor and give it the attention it deserves.
