In some cases, we indicate that a link exists on your page but it's not easily visible within the Page report.
This article helps explain why this happens and gives some tips and tricks for identifying the link.
Reasons why a link might not be visible
The link only displays at a certain browser width
Many responsive sites contain links for both mobile and desktop versions. The mobile version can be hidden until a mobile browser id detected. Try to resize your browser window to see if the link appears.
The link was not intended to be visible
Links in your source code may not be visible as they were not intended to be interactive. For example, these may be intended for search engines, robots, or other purposes. If the Siteimprove crawler can find these links then search engines and other crawlers can also find them.
The link is on a menu or similar element
Tips for finding the missing link
Switch the Page Report into "Show HTML" mode by clicking on the icon at the top of the Page Report. This will often show you where the link resides in the HTML, and reveal the link.
If after switching to "Show HTML" the link is still not highlighting, try using the "Find" feature (Ctrl+F) in your browser to locate the link.
When searching for the link you may have more success performing a partial match on the link. For example, if trying to find "http://www.example.com/news/article/2015/02/news.html" perform a search for "news.html".
In some situations, it may require your developers to explain why the link is not visible, or you can always submit a support ticket and we can review it with you.
