My Tool: Reputation Checker
Yes, it is Google. For example, google this:
For starters, meaning of this query is search for “worthofweb.com” -exactly same phrase-, but do not include worthofweb.com pages in the search results.
By this way, you can see which sites are talking about you or linking to you without using any programs.
Also, on the left side, click “show search tools” > “past month” or “past week” to filter your search.
For further use, go to Google Alerts, and set an alert with this search, then receive email when new results exist.
