To prevent this from happening, search engines try to determine the original source, so they can show this URL for a relevant search query and filter out all the duplicates. As we know search engines do a pretty good job at filtering duplicates, but it is still pretty difficult to determine the original webpage. It can happen, when the same block of text appears on multiple websites, the algorithm will decide the page with the highest authority \/ highest trust will be shown in search results even though this isn\u2019t the original source. In the case Google detects duplicate content with the intent to manipulate rankings or deceive users, Google will make ranking adjustments (<strong>Panda filter<\/strong>) or the site will be removed entirely from the Google index and search results.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter img-responsive size-full\" src=\"https:\/\/www.seoreviewtools.com\/wp-content\/uploads\/Duplicate-Content-Checker-Plagiarism-Detection-Tool.png\" alt=\"Duplicate Content Checker\"><\/p>\n<h2>How does the duplicate content checker work?<\/h2>\n<ul class=\"explanation\">\n<li>Find indexed duplicate content, using URL or TEXT input.\n<ul>\n<li>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.)<\/li>\n<li>Use text input to get more control over the input.<\/li>\n<\/ul>\n<\/li>\n<li>Similar content is extracted, returned and marked as: Input URL, Internal duplicate, External duplicate.<\/li>\n<li>Export the results to .CSV. and use Excel \/ Open Office spreadsheet to view, edit or report your results.<\/li>\n<\/ul>\n<h2>How to use these results?<\/h2>\n<p><strong>Internal duplicates<\/strong> In most cases you\u2019ll start solving internal duplicate issues. Because these problems exist in your own controlled environment (your website). Different methods can be used to remove internal duplicates, depending on the nature of the problem. Some examples:<\/p>\n<div class=\"info-block\">\n<ul class=\"default\">\n<li>Minimize boilerplate repetition<\/li>\n<li>Use a 301 permanent redirect<\/li>\n<li>Use a canonical tag<\/li>\n<li>Use Parameter Handling in Google Webmaster Tools<\/li>\n<li>Prevent an URL from being index.<\/li>\n<\/ul>\n<\/div>\n<p><strong>External duplicates<\/strong> External duplicates can be <span class=\"st\"> a whole nother story<\/span>, because you can\u2019t just make adjustments to your own site and solve the problem. Some examples how you can remove external duplicates:<\/p>\n<div class=\"info-block\">\n<ul class=\"default\">\n<li>Contact webmasters, and ask them to remove the copies of your content.<\/li>\n<li>If an another site is duplicating your content \/ in violation of copyright law and contacting them doesn\u2019t solve the problem, you can use this form to notify Google: <a href=\"https:\/\/support.google.com\/legal\/troubleshooter\/1114905\">https:\/\/support.google.com\/legal\/troubleshooter\/1114905<\/a> .<\/li>\n<\/ul>\n<\/div>\n<h2>Tool limitations<\/h2>\n<ul class=\"default\">\n<li>This tools automatically extracts the text form a web page to use as input to detect duplicate content. This is not always the exact block of text you like to check for duplicates. In the case it\u2019s better to use the text input field.<\/li>\n<li>New content needs to be indexed before it can be returned by this tool. If the page \/ content is less than 2 days old, chances are slim you will get any results.<\/li>\n<li>Not all duplicates, found online, are returned by this tool. But compared to other tools it returns a pretty large sum.<\/li>\n<\/ul>\n<h2>External recourses:<\/h2>\n<ul class=\"explanation\">\n<li>Google, <a href=\"https:\/\/support.google.com\/webmasters\/answer\/66359?hl=en\">https:\/\/support.google.com\/webmasters\/answer\/66359?hl=en<\/a><\/li>\n<li>Search Engine Land, <a href=\"http:\/\/searchengineland.com\/library\/google\/google-panda-update\">http:\/\/searchengineland.com\/library\/google\/google-panda-update<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"Duplicate content checker \/ Plagiarism detection.
