The Smart Way to Shorten Your Links and Stay in Control

The Smart Way to Shorten Your Links and Stay in Control

23.Apr.2021
A lot of sites, like Twitter, are all about short links. Have you ever wondered why people use short links? Or do you want to know how you can make your own?   Sharing and remembering URLs from short links is easier than from long URLs. Shortening URLs can be a great way to see how far they are being clicked on. In addition, it offers a way to protect links you make and change them later.   How to Shorten a Link   The following are two simple ways to shorten your links, and both have their advantages.   1. Shorten your URL with SnipURL, TinyURL and Bit.ly.   Numerous websites are dedicated to providing link shortening services. If you Google "shorten my link" you'll get lots of search results.   You can use both of them easily. Simply copy and paste your URL into the shortening box and click the button to receive your shortened URL. Tracking your links with Bit.ly is also free.   Essentially, links in this format are not controlled by you, which means that when you link to a domain which disappears in the future your link will no longer work. Furthermore, you can't alter the link later.   Some popular link shorteners might cause an email to be flagged as spam as spammers have been known to use them to send out URLs they didn't intend to send. Avoid using them in newsletters or autoresponders.   Although they can be useful in situations where you need a super short link, they are not ideal for social networks.   2. Use a script on your own domain   The GoCodes plugin for WordPress is a simple way to shorten links and remain in control. A shortened link can also be edited so that it points to a new URL. As with any other plugin, you can install it the same way. Go to "Plugins" then search for "GoCodes" then install and activate.   Affiliate marketers will find this especially useful. A short link pointing to Big Website Host A is what I can make if I recommend that host right now. I could change the link my short link points to and redirect everyone to the new recommendation if I realize next week that something better is available. Short links that point to me will still work, but now they'll point to BigHosting B instead.   There's also the free script Shorty if you're not using WordPress. Your URL is shortened with the short link. There are a lot of great URL shorteners available so you should search for them and compare your options.   The base for your shortened links can be your own domain, which will allow you to continue building links to your own website and further enhance your brand. It also means you're less likely to have your newsletter flagged as spam.

Security Risks of URL (Link) Shortening Services

Security Risks of URL (Link) Shortening Services

23.Apr.2021
URLs (website URLs) are shared through email, blogs, social media sites, book marking websites, and word of mouth, but we seldom consider how this simple act, if at all, can raise security threats. I will discuss some of the risks associated with sharing shortened URLs provided by URL Shortening Services.   What is URL Shortening?   The idea behind URL shortening and link shortening is very simple, shorten a long URL by encrypting it into a shorter one. These services shorten URLs in this manner. The original lengthy URL is shortened and then mapped to the shorter shortened URL.   The target link would typically be reduced from 220 characters to 25 characters, and this is what you would pass on to your friends. A short URL will be mapped to the original by the shortening service and directs the user.   Social Media Sites   The 140 character limitation imposed on Twitter messages is problematic at best because sharing links is a major problem. A result of this problem is that URL Shortening Services have proliferated and they do a fantastic job on the whole. However, the risks for trusting shortened links with third parties are substantial.   A majority of URL shortening services that are free are available online. My website contains a more complete listing of these services.   Security Risk 1 - Link Manipulation   What is the link destination? Once you click on the link, it's usually impossible to determine your final destination. The true target is obscured.   Although these risks apply to all link masking technologies, you can usually determine the validity of a link, for example, when you receive one via email or when you hover your mouse over the URL to see its destination address.   This first line of defense is no longer there because all shortened URLs take you to a place you aren't prepared for. These URL shortening services have been used in phishing scams for this very reason.   Security Risk 2 - Ineffective Spam Filters   It is not possible for spam filter systems to evaluate the URL's legitimacy because there is no original URL available. Keeping track of this problem is nearly impossible since the shortening services are free and take seconds to use.   Spam complaints are taken very seriously by many shortening services and malicious URLs are blocked immediately. One service currently scans registered URLs to detect blacklisted sites and disables the short URLs; others remove them, but then the other takes their place.   Even Safe Browsing features in web browsers such as Google Chrome and Firefox which warns customers about malware or phishing sites cannot protect you from shortened URLs. The user won't receive a warning, but will be sent straight to the potentially dangerous page.   Security Risk 3 - Compromised Shortening Service   I've used URL shortening services that have been shady for a considerable number of years. By typing in an invalid URL, several allow me to drop down to their directory structure. A hacked site would expose popular shortened URLs to malicious sites and phishing scams.   Security Risk 4 - Privacy Issues   Linkshortening services enable users to track their activity across multiple domains, resulting in possible privacy issues.   Security Solutions - Transparency   URL shorteners are constantly trying to solve security issues by adding "see before you click" to their short URLs.   The destination address is optionally visible by prefixing any tinyURL address with "preview". A BudURL shortened link can be previewed by adding a "?" to the end of the URL. When you hover the mouse over the short URL, the destination page appears as a popup. Conclusion   You should pay very close attention to the links you click and to whether or not the source is known to be reliable. Be careful when opening links from our friends. We've all been too flippant with them.
