Lists such as this may appear to be a good idea but are out of date moments after are created and are probably more of a danger than a help.
Using something dynamic makes more sense, e.g.
https://www.getsafeonline.org/checkawebsite/
It also helps if you have an understanding of how domain names and URLs are constructed and work in the context of a browser, e.g
www.tesco.com or
www.tesco.co.uk or
www.tesco.ie all look ok, with or without the www. These are often referred to as primary or main domains (terminology here is all over the place so apologies in advance if this rubs anyone up the wrong way)
realfood.tesco.com is a subdomain and is fine - the “.tesco.com” part is intact and traffic goes to Tesco
Avoid anything that looks like tesco2u.com, tesco2you.co.uk, tescojersey.com, tescodvd.co.uk, tescodiet.com, tescodiet.co.uk, tesco-diet.co.uk.
Also unfamiliar endings (e.g. tesco.za or tesco.ug or tesco.cn or tesco.ru) are best avoided unless you are shopping in South Africa or Uganda or China or Russia.
Typing the domain name/URL* is safer than clicking on a link. Copy and pasting it is somewhere in the middle.
HTTPS:// at the start is a lot safer than HTTP:// (The “S” stands for secure)
Spoofing: Someone sends you a link that looks innocent such as
www.tesco.com, but when you click on it it takes you to http://www.tesco-give-me-your-money.com (www.tesco-give-me-your-money.com) - you need to be distrustful of links contained in emails and message and watch carefully where they take you once clicked on.
*URL or Universal Resource Locator is a path to a specific page or object, e.g.
www.tesco.com
