Example: <meta name=”description” content=”Content description" />
Having this tag correctly configured is very important at a strategic level, so important that you have to invest time in seeing which is the correct meta description to use in each URL.
It is highly recommended that you include the keywords for which we want to position a URL.
Just because an SEO tool says there are no errors doesn't mean it's right.
The same thing happens here as with the alt attribute of images, the fact that there is an error does not mean that we should not invest time in analyzing it manually.
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 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.
Pages contain frames
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.
Even if SEMrush gives an error, it is always good, due to the multitude of types of “doctype declared” that exist, to check it with “W3Cs validation service”.
Having the “declared doctype” poorly defined can cause problems with the HTML tags we can use.
Although it is true that this error is something that is more a part of custom number code philippines programming, it will actually be very difficult to find it in Wordpress, Prestashop and others.
Pages have too many on-page
In this case, what it is telling us is that we have too many links in a URL.
This makes it difficult for Google to analyze all of the linked content.
If you don't fix it you could have two problems.
The most important thing is that you can affect your crawler budget and, on the other hand, you will spread the authority of that URL so much that it will not provide any value on its own.
This is something that can be solved in a thousand ways.
Normally when we have this notification it is because we have the same link from different points.
So by removing one of these, we shouldn't have many more problems.
Another option is to reduce the number of items that have links and thus control the number of links.
Pages use Flash
If you see this error, it means you have a really old website.
Flash is in .swf format, it is a language or file that Google does not understand.
I confess that I came to love Flash (MX) but it was totally understandable that he banned it.
