1. Avoid Unnecessary FormsA good Web safety rule of thumb is to avoid filling out forms that require personal information in order to keep anything from being entered into public, searchable record, aka Web results. You can use BugMeNot to avoid filling out unnecessary forms that ask for too much personal information.
2. Clean Your Search HistoryMost Web browsers keep track of every single Web site you type into the address bar. This Web history should be periodically cleared out not only for privacy's sake, but also to keep your computer system running at top speed. In Internet Explorer, you can delete your search history by clicking on Tools, then Internet Options. In Firefox, all you need to do is go to Tools, then Options, then Privacy. You can also clear your Google searches very easily.
3. Log Out Of Search EnginesMost search engines these days require you to create an account and log in to access the full array of their services, including search results. In order to best protect your privacy, it's always a good idea to log out of your account after executing your Web searches.
In addition, many browsers and search engines have an auto-complete feature that suggests endings for whatever word you might be typing in. This is a very convenient feature, however, if you're looking for privacy it's something you'll want to get rid of.
4. Watch Your DownloadsBe extremely cautious when downloading anything (software, books, music, videos, etc.) from the Web. This is a good idea for privacy advocates, but it's also a great way to keep your computer from freezing up and malfunctioning. Be very cautious when choosing what to download from the Web; some programs include adware that will report your surfing habits back to a third-party company that will then use that information to send you ads and unwanted emails, otherwise known as spam.
5. Use Common SenseThis is pretty self-explanatory: don't go to places on the Web that you would be embarrassed to have your wife, husband, children, or employer see. This is a very low-tech way to protect your Web privacy, and yet, out of all the methods on this list, might be the one that is most effective.
6. Guard Your Private InformationBefore sharing anything online - on a blog, website, message board, or social networking site - be sure it's not something you would mind sharing in real life, off the Web. Don't share information that could identify you in public, especially if you are a minor. Keep identifying details, like user names, passwords, first and last names, addresses, and phone numbers, to yourself. Your email address should be kept as private as possible, because an email address can be used to track other identifying information (see How to Find Information Using a Reverse Email Search).
7. Use Caution When Using Social MediaSocial networking sites such as Facebook are extremely popular, and for good reason: they make it possible for people to connect with each other all over the world. It's important to make sure that your privacy settings are set appropriately and that what you share on social networking sites would not reveal anything of a personal or financial nature.

8. Watch Out For ScamsIf it seems too good to be true, than it probably is - and this especially applies on the Web. Emails promising free computers, links from friends that seem legit but lead to virus-laden websites, and all sorts of other Web scams can make your online life quite unpleasant, not to mention add all sorts of nasty viruses to your computer system.
Think carefully before following links, opening files, or watching videos sent to you by friends or organizations. Watch for signs that these might not be for real: these include misspellings, lack of secure encryption (no HTTPS in the URL), and improper grammar.
