Preventing Duplicates Before Import<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-use-unique-identifiers\" style=\"font-size:21px\">Use Unique Identifiers<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Each event should have a unique identifier such as an event ID, URL, or UID (for iCal feeds).<\/li>\n\n\n\n<li>If your source feed does not provide unique IDs, duplicates are more likely to occur.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-adjust-import-settings-thoughtfully\" style=\"font-size:21px\">Adjust Import Settings Thoughtfully<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If you install the <a href=\"https:\/\/theeventscalendar.com\/extensions\/ea-additional-options\/\" target=\"_blank\" rel=\"noreferrer noopener\">Additional Options for Event Aggregator extension<\/a>, there is an added option under <strong>WP Admin Dashboard<\/strong> <strong>\u2192<\/strong> <strong>Events \u2192 Settings \u2192 Imports<\/strong>, where you can choose how previously imported events should be handled\u2014whether to overwrite, preserve, or skip duplicates.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-stick-with-one-source\" style=\"font-size:21px\">Stick with One Source<\/h4>\n\n\n\n<p>Import from the same feed or file consistently. Changing sources can cause the system to misidentify events and import duplicates.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-be-strategic-with-scheduling\" style=\"font-size:21px\">Be Strategic with Scheduling<\/h4>\n\n\n\n<p>Avoid overly frequent imports. Frequent runs can increase duplicates, particularly if event data changes. A daily or weekly schedule usually strikes the right balance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-managing-duplicates-after-import\">2. Managing Duplicates After Import<\/h3>\n\n\n\n<p>Despite preventive actions, duplicates may still appear.
