Reasons to Block Ads

Thousands of websites are being created every day, and it’s getting more and more challenging to keep track of what’s safe for kids to access and what could be potentially harmful. Parents usually turn off blacklists and websites categorized as mature or unsafe websites. Sometimes pop-ups and other advertisements on social apps such as YouTube ads and autoplaying videos, can also be inappropriate for children. In such cases, website blockers are pretty helpful to keep the children’s web experience safe and free from online dangers.

Blocklist filtering is one of the most common forms of website blocking today.  When enabled, users cannot attempt to go to a website if the URL of that website is listed as an inappropriate site. As long as the website is on that list, the site stays blocked, providing a worry-free experience to parents.

Age restricted content - ad blocker

However, blocklists cannot be updated as quickly when new unsafe websites are created or when the content on the same websites changes. If users rely on outdated blocklists and ad blocker to keep explicit content off-limits and block ads, children still can gain exposure to pornography, pop ups, dangerous websites, and other 18+ content.

What Makes Website Blocker an Essential Tool?

Implementation of ad block and web blockers can offer tenfold benefits for businesses and organizations. The key benefits of ad block and website blockers are that they prevent internet users from visiting dangerous websites harboring malware or ransomware websites known for scams, phishing attacks, and hiding their true identity behind proxy servers. These websites can cause data theft and potential harm to a company’s confidential data.

An ad blocker and web blocker prevent employees from accessing time-wasting websites that do not contribute to work. Studies show that 30-40% of employees use the internet for non-work-related websites, and 77% of the employees access social media sites in the office. Surprisingly, 70% of the visit happen between office hours, i.e., 9 am to 5 pm. Blocking these websites can significantly increase employees’ productivity.

Another added benefit of such tools is to prevent viewing inappropriate content on the office premises. This is relevant in places with public WiFi access, such as restaurants, bars, and shopping malls. Blocking such websites is useful in places with families where children could be exposed to pornography, violence, racism, hate speech, and religious intolerance. Not only will it keep people safe, but it will also offer the business a competitive edge over those who fail to protect their customers.

So, if the administrator applies one policy for a group of users and another policy for another group, the procedure should be straightforward to make customized settings easy.

3. Money

Money should not be an essential consideration because recovering from malware is more challenging than purchasing a premium website blocker. However, if an organization is working on a limited budget, it should look for solutions with no upfront costs with flexible pricing plans.
