One of the tools that could be sued when you are searching on the internet is to look for links that are provided by the trusted sites you know. because there are many malicious files on the internet and the also the meaningless ones so you should look for some trusted sites as a source of information. If what you are looking for should be based strictly on facts and truth then you should find a trusted site to help you.
It is common that sites will give links to other sites if they also know and have proven that they are trustworthy as it can affect their reputation. That is why a site who has proven itself will surely be wary of just trusting someone. That is why before they put links at the end of their site’s content they check it to be a good site. Also, they are sure to be related to the original site on the topic or content so you can also go to that other sites.
This method is very nice because you have been given lesser options so you will not have a long list of choices. You can see faster what you are looking for as the links are directly accessible with just a click.
The disadvantage of it is that you should know a site where you can find the links. Just like the directories who can encounter a problem with links not functioning, this method too can have links that are broken.
