The issue details page is where you can get more specific details about problems on your site. You can find what the problem is, where it's located, how to fix it, and all of the technical data needed to make the right decisions. This is probably the most important page in the entire "Site" section. The information displayed in this page varies depending on which issue is chosen.
While each issue's data table will be slightly different, there are many principles that are shared throughout all issue pages, let's breakdown the page and see how we can use it to optimize our site:
On the top of the page you will be able to see what site you are looking at, basic crawl statistics, quickly switch to view another issue or export issue data into an Excel file
After the top section you will get some basic information about the issue like the number of times this issue's been found, priority of the issue, a chart showing the number of times this issue's been found on your site over time and a Help with this issue button which by clicking on it you will get a step by step guide to fix this issue:
After the chart you will see a table showing you specifics of the issue on your site, data being shown at each pages of each issue will be unique in order to show you the most helpful data for fixing the issue. You will get status codes of problematic pages for 4xx errors; redirect URL, number of redirects in redirects issues; number links on the page or number of links pointing to this page in links related issues etc. In most pages you will be able to click on the arrow button to expand each problematic pages to get more info about what's happening in the pages that's causing the issue, clicking on the double arrow button at the table header will expand all the info for all problematic pages, you can click on the little icon next to each URL shown in the table to access the URL directly as well.
