Pages have no hreflang and lang attributes
We have already seen that we can know if we have a conflict or an implementation failure.
In this case, it is telling us that a URL does not have this attribute.
We don't have to worry if we get a warning if our website is not in different languages.
If our domain has several languages, all URLs must have this tag.
So this part of the tool will be very useful to detect possible failures.
Current tools for creating the hreflang tag do not work 100% in all iran mobile database cases, we must be careful not to lose this functionality.
In the event of a failure, it is much better for a programmer to provide a definitive solution to this problem.
Frames or iframes are code fragments that we can use on our website to extract or include information from other websites, which goes against Google's quality policies.
This is something that cannot always be solved because in some cases it is a necessity, such as including a video or variable information.
Another thing to keep in mind is that frames are very old HTML tags that are not supported by HTML languages such as HTML5.
Even so, we have to be able to provide a solution or find a formula to try to remove the frames or iframes from our URLs.
There are always options.
Pages don't have doctype declared
It is difficult to define the “declared doctype” since it has always been known by this name, the technical definition would be “document type declaration” that indicates what HTML format the browser will be able to receive and the way in which the HTML is serialized.
