Welcome to the Q&A Forum

Yes I mentioned in my case I use Semrush and there is a dedicated space for that specific parameter. The easiest way to get your log files is logging into your cPanel and find an option called Raw Log Files. If you are still not able to find it, you may need to contact your hosting provider and ask them to provide the log files for your site. Raw Access Logs allow you to see what the visits to your website were without displaying graphs, charts, or other graphics. You can use the Raw Access Logs menu to download a zipped version of the server’s access log for your site. This can be very useful when you want to quickly see who has visited your site. Raw logs may only contain a few hours’ worths of data because they are discarded after the system processes them. However, if archiving is enabled, the system archives the raw log data before the system discards it. So go ahead and ensure that you are archiving! Once you have your log file ready to go, you now need to gather the other data set of pages that can be crawled by Google, using Screaming Frog. Crawl Your Pages with Screaming Frog SEO Spider Using the Screaming Frog SEO Spider, you can crawl your website as Googlebot would, and export a list of all the URLs that were found. Once you have Screaming Frog ready, first ensure that your crawl Mode is set to the default ‘Spider’. Then make sure that under Configuration > Spider, ‘Check External Links’ is unchecked, to avoid unnecessary external site crawling. Now you can type in your website URL, and click Start. Once the crawl is complete, simply a. Navigate to the Internal tab. b. Filter by HTML. c. Click Export. d. Save in .csv format. Now you should have two sets of URL data, both in .csv format: All you need to do now is compare the URL data from the two .csv files, and find the URLs that were not crawlable. If you decided to analyze a log file instead, you can use the Screaming Frog SEO Log File Analyser to uncover our orphan pages. (Keep in mind that Log File Analyzer is not the same tool that SEO spyder) The tool is very easy to use (download here), from the dashboard you have the ability to import the two data sets that you need to analyze If the answer were useful do not forget to mark it as a good answer ....Good Luck
