Errors
As these are serious errors, these data must be treated urgently.
Whether or not SEMrush reports a bug, we have to check these points manually to correct what the program cannot see, such as incorrect tagging or incorrect structure.
For this part you can use complementary tools like screaming frog to see the data structures.
Pages have duplicate content issues
Ask yourself why Google is going to show the same information twice in the same search.
If we have the same content in two URLs of our domain, Google may consider which one should be ranked first and whether both options are relevant to the user.
This is usually a very typical problem caused by a lack of strategy. It is best to have an Excel with the structures of titles, meta descriptions, H1 and H2 of your entire domain.
With this well-defined structure and objectives, you should not have any duplication problems.
Pages have duplicate meta descriptions
HTML tag: <meta name="description" content="We are an SEO Agency."/>
Meta descriptions are a fundamental point to work on for two reasons: on the one hand, it is a place that contains words that the user has searched for and, on the other hand, it is a good area to attract the user's attention.
This is what is known as CTR.
If you think about how to get users' attention and what words will be used to access that information, you will have perfect meta descriptions.
We should not interpret a duplication with an exact text but with a percentage or part of it.
That is, Google is a mathematical processor and will evaluate the duplicate number code philippines content of a description at a percentage level.
It is very typical when we have, for example, two services or two very similar products, for example a “red telephone” and a “blue telephone”.
When products have the same characteristic and only one part of the description changes, duplication problems often arise.
Here we have several options, but the most advisable thing is to work on the description of each product by introducing different words that users search for in each one.

Page doesn't have a title tag
HTML tag: <title>SEO Agency</title>
Not having this tag in your domain's HTML can result in it not ranking for the terms you need, and that's where its importance lies.
The title is a pillar of SEO, which means that it is something we must take care of as much as possible.
A Google rule is that this element must be unique across all URLs in the domain, and we advise you to make it unique across the entire Internet or be the first to create it.
To solve this, you have to resort once again to your SEO strategy.
If you don't see any possible options to solve the duplicate titles, you can use a trick: say it as it would be said in another country.
In this way, you will also attract customers of other nationalities residing in your sales area.
You can also use what is called a “long tail” or say the same thing but broadening the concept.
