Find indexed duplicate content, using URL or TEXT input.
Use URL input to extract the main article content / text found in the body of a web page. Navigational elements are removed, to reduce noise (otherwise a lot of pages would be falsely identified as internal duplicates.)
Use text input to get more control over the input.
Select advanced options to choose one or multiple data points, used to detect duplicate pages. Selecting multiple data points, will get you more specific and even better matching results. (These data points are automatically extracted from the page content or text input).
Similar content is extracted, returned and marked as: Input URL, Internal duplicate, External duplicate.
Export the results to .CSV. and use Excel / Open Office spreadsheet to view, edit or report your results.
