1. Do not edit your Wikipedia page. Wikipedians will catch on to most companies and PR agencies trying to get rid of negative items. If it is true and there is a valid source then the negative item will likely stay. The best practice for this is to get your message out to the reporters so it can be cited. Then contact a Wikipedia expert.
  2. Do not delete Social Media comments. Unless you have a written policy commenting then you should leave this alone. It comes back 10 fold more often than not. Take time now to write and publish a policy then delete only comments that violate that policy.
  3. Do not view LinkedIn profiles while logged in. They may be able to see that you have viewed the page. What they do with the information about viewing their profile is unknown but it is not a good general practice to let a person know you are investigating them.
  4. Do not post a press release on a Press Release site, post it on your own website. The reporters and bloggers will most likely link to your website which will help with SEO and help you control the flow of information. You may not have an SEO issue at the time but you will if reporters publish online.
  5. Do not surf and do things on the internet from your corporate IP. People may be tracking your actions so be careful and it may be a good idea to use Tor, an anonymous browser.
  6. Do Not, Not reply to bloggers. Bloggers can have a very powerful audience and some viral capacity so treat them the same way you treat a reporter from a large publisher.
  7. Do not leave complaints unattended. Every Tweet, Facebook post or any other network should have a reply. Turn a negative commenter into an advocate if you can. Be very careful with how online complaints are handled. You will most likely need to consult with a Crisis PR Pro.
