How to Tell If a Website Is Safe (A Senior's Guide to Staying Secure Online)

Every day, millions of people visit websites to shop, read the news, check their bank account, or look up health information. Most websites are perfectly safe. But some are set up by criminals who want to steal your personal details, your money, or both.

The good news is that spotting a dangerous website is not difficult once you know what to look for. In this guide, we will walk you through the simple checks you can make — in plain English, with no technical jargon — so you can browse the internet with confidence.

Why Website Safety Matters

You might wonder, "What is the worst that could happen if I visit a bad website?" Unfortunately, quite a lot:

• Identity theft. A fake website can trick you into typing in your name, address, date of birth, or National Insurance / Social Security number. Criminals use this information to open credit cards or bank accounts in your name.
• Financial loss. Scam shopping sites take your payment but never send the goods. Some steal your card details and make additional charges.
• Viruses and malware. Some websites quietly install harmful software on your computer. This software can spy on everything you type, including passwords.
• Emotional distress. Being scammed is stressful and upsetting. It can shake your confidence about using the internet at all.

None of this is meant to frighten you. It is meant to show you why spending a few seconds checking a website is well worth the effort. Think of it like looking both ways before you cross the road — a quick, sensible habit that keeps you safe.

The Padlock Icon: HTTPS Explained Simply

The very first thing to check is the padlock icon in your browser's address bar. This is the bar at the top of the screen where you see the website's address.

When you visit a safe website, you will usually see a small padlock icon to the left of the address. This padlock means the website uses something called HTTPS (you may notice the address starts with https:// rather than just http://).

What does HTTPS actually do? It scrambles (encrypts) the information that travels between your computer and the website. So if you type in your credit card number on an HTTPS website, that number is protected while it travels across the internet. Without HTTPS, that information could be read by anyone snooping on the connection.

Important: The padlock tells you the connection is secure, but it does not guarantee the website itself is honest. A scammer can set up a fake website with HTTPS. So the padlock is a good first sign, but you need to check a few more things as well.

How to check for the padlock

1. Look at the address bar at the very top of your browser (Chrome, Edge, Safari, or Firefox).
2. You should see a small padlock icon on the left side of the web address.
3. If you see a warning symbol, a triangle with an exclamation mark, or the words "Not Secure," be very cautious. Do not enter any personal information on that page.

Checking the URL for Fakes

The URL is simply the website's address — the text in the address bar, such as www.amazon.co.uk or www.walmart.com. Scammers create fake websites with addresses that look almost right, but not quite.

Here are some tricks they use:

• Misspelled names. For example, www.amaz0n.co.uk (with a zero instead of the letter "o") or www.waImart.com (with a capital "I" instead of a lowercase "l"). These are easy to miss at a glance.
• Extra words. Something like www.amazon-deals-login.com is not Amazon. The real Amazon website is simply amazon.com or amazon.co.uk.
• Strange endings. Real UK sites usually end in .co.uk or .com. Be suspicious of addresses ending in unusual combinations like .xyz, .top, or .buzz — especially if the site claims to be a well-known brand.

A helpful habit: If you want to visit your bank, a shop, or any important website, type the address directly into the address bar yourself rather than clicking a link in an email or text message. This is one of the simplest and most effective ways to avoid fake sites. You can also use a search engine like Google to find the official site.

If you receive emails that claim to be from your bank or a delivery company, be extra careful with any links they contain. We have a separate guide on how to spot scam emails that covers this in detail.

Common Red Flags on Websites

Even if the padlock is there and the address looks correct, the website itself might give you clues that something is not right. Watch out for these warning signs:

1. Aggressive pop-ups

If a website immediately bombards you with pop-up windows — especially ones saying "You have won a prize!" or "Your computer is infected!" — close the page straight away. Legitimate websites do not behave this way.

2. Urgent language and pressure tactics

Phrases like "Act NOW or lose your account," "Only 2 minutes left to claim," or "Your computer is at risk — call this number immediately" are almost always scams. Real companies do not pressure you with countdown timers or threatening language.

3. Spelling and grammar mistakes

Professional businesses proofread their websites carefully. If a site is full of spelling errors, odd grammar, or sentences that do not make sense, it is a strong sign that it was thrown together quickly by someone who is not legitimate.

4. Too-good-to-be-true deals

A brand-new iPhone for fifteen pounds? A designer handbag at ninety percent off? If the price seems unbelievably low, it probably is not real. Scam shopping sites lure people in with impossible bargains, take the payment, and disappear.

5. No contact information

A trustworthy business will have a clear "Contact Us" page with a real address, phone number, and email. If the only way to reach the company is through a generic contact form — or if there is no contact information at all — that is a red flag.

6. No returns or privacy policy

Legitimate online shops are required by law (in both the UK and the US) to have a returns policy and a privacy policy. If you cannot find either of these, be wary.

Trusted Shopping Sites

When shopping online, sticking with well-known retailers is the safest approach. Here are some widely trusted sites:

• Amazon (amazon.com / amazon.co.uk)
• Walmart (walmart.com)
• John Lewis (johnlewis.com)
• Marks & Spencer (marksandspencer.com)
• Target (target.com)
• Boots (boots.com)
• Argos (argos.co.uk)

If you find a product on a website you have never heard of, do a quick search before buying. Type the website name followed by "reviews" or "scam" into Google and see what other people say. Five minutes of checking can save you a lot of trouble.

When you do shop online, using a credit card (rather than a debit card or bank transfer) gives you extra protection. In the UK, Section 75 of the Consumer Credit Act covers purchases between one hundred pounds and thirty thousand pounds. In the US, federal law limits your liability for unauthorised credit card charges to fifty dollars. Paying by bank transfer offers almost no protection if something goes wrong.

How to Check If a Site Is Legitimate

If you are unsure about a website, here are two practical ways to investigate it:

Check the WHOIS record

Every website is registered with details about who owns it. You can look these up for free:

1. Go to whois.domaintools.com or who.is in your browser.
2. Type the website address into the search box and press Enter.
3. Look at the results. When was the site created? If it was registered only a few days or weeks ago, be cautious — especially if it claims to be a long-established company. Also check the registrant's country. If a site claims to be a British or American company, but it was registered in a completely different country, that is suspicious.

Read reviews

Search for the website name plus the word "reviews" in Google. Look for reviews on independent sites such as Trustpilot (trustpilot.com) or the Better Business Bureau (bbb.org) in the US. If many people report being scammed, steer well clear.

You can also use Google's Safe Browsing tool. Go to transparencyreport.google.com/safe-browsing/search and paste in the website address. Google will tell you whether it has detected any problems with that site.

Setting Up Safe Browsing on Your Computer

Your web browser already has built-in safety features. Make sure they are turned on:

Google Chrome

1. Click the three dots in the top right corner, then choose Settings.
2. On the left, click Privacy and security.
3. Click Security.
4. Select Enhanced protection for the strongest safety. This warns you about dangerous websites, downloads, and extensions before you visit them.

Microsoft Edge

1. Click the three dots in the top right corner, then choose Settings.
2. Click Privacy, search, and services on the left.
3. Scroll down to Security and make sure Microsoft Defender SmartScreen is turned on.

Safari (Mac and iPhone)

1. Open Safari and click Safari in the menu bar, then Settings (or Preferences on older versions).
2. Click the Security tab.
3. Make sure Warn when visiting a fraudulent website is ticked.

These settings cost nothing and add a valuable layer of protection. They will not catch everything, but they will warn you about many known dangerous sites.

For even more protection while browsing, you may want to consider using a VPN. We explain what a VPN is and how it works in our guide on what a VPN is and why it matters.

What to Do If You Entered Information on a Suspicious Site

If you think you may have typed personal or financial information into a website that turned out to be fake, do not panic. Acting quickly can limit the damage:

1. Contact your bank or card provider immediately

Call the number on the back of your bank card. Tell them you may have entered your card details on a fraudulent website. They can freeze your card and issue a new one. In most cases, they can also reverse any unauthorised transactions.

2. Change your passwords

If you entered a password on the suspicious site, change it straight away — and change it on any other site where you use the same password. This is a good reminder of why using different passwords for different websites is so important. Our guide on how to create strong passwords can help you set up passwords that are both secure and easy to remember.

3. Run a security scan

If you are worried that the website may have installed something harmful on your computer, run a scan with your antivirus software. Windows computers come with Microsoft Defender built in. Open it by searching for "Windows Security" in the Start menu, then click Virus & threat protection and choose Quick scan.

4. Report the scam

• In the UK: Report to Action Fraud at actionfraud.police.uk or call 0300 123 2040.
• In the US: Report to the Federal Trade Commission at reportfraud.ftc.gov.

Reporting helps authorities shut down scam websites and protect other people.

5. Monitor your accounts

Keep a close eye on your bank statements and credit report for the next few months. If you see any transactions you do not recognise, report them to your bank immediately.

A Quick Checklist You Can Print Out

Here is a simple checklist you can refer to whenever you visit a new website:

• Padlock icon visible in the address bar? Good sign.
• Web address looks correct with no odd spellings or extra words? Good sign.
• No aggressive pop-ups or urgent warnings? Good sign.
• Prices seem realistic? Good sign.
• Contact details (address, phone, email) are clearly listed? Good sign.
• Privacy policy and returns policy exist? Good sign.
• Reviews from other customers are positive on independent sites? Good sign.

If any of these checks raise a concern, trust your instincts and leave the site. It is always better to be cautious than to take a risk.

Frequently Asked Questions

Is the padlock icon enough to prove a website is safe?

No. The padlock means your connection to the website is encrypted, which is important. However, it does not prove that the people running the website are honest. Scammers can set up websites with padlocks too. Always check the web address carefully, look for red flags on the page, and search for reviews before entering any personal information.

What should I do if a website asks me to download something?

Be very cautious. Only download software from websites you trust completely — such as the official website of the software maker (for example, adobe.com for Adobe Reader). If an unfamiliar website asks you to download a file, especially with urgent language like "Your computer is at risk," close the page immediately. Legitimate websites rarely force you to download anything.

Can I get a virus just by visiting a website, without clicking anything?

In most cases, simply visiting a website will not infect your computer — especially if your browser and operating system are up to date with the latest security updates. However, very outdated software can have weaknesses that criminals exploit. This is why keeping your computer updated is so important. Make sure automatic updates are turned on in your computer's settings, and keep your browser up to date as well.

Staying safe online does not require any technical expertise. It is really about building a few simple habits — checking the padlock, reading the web address carefully, and pausing before you enter personal information. With these habits in place, you can enjoy everything the internet has to offer with much greater peace of mind.
