SEMrush you have the option to analyze

I assume that if you are going to change the appearance of your domain you will not make the same mistake of selecting another template with the same problem.

Pages have a low word count
In this case, what it is telling us is that these URLs do not have enough words to comply with Google regulations.

This is not something you need to fix immediately, remember that it is not an error but a warning.

Before taking any action, it is highly advisable that you analyze the data of the affected URLs.

To solve this, remember that with a domain or a single URL.

If the URL is already positioned for the keywords that need to be iran mobile database positioned, I do not recommend that you touch the text density.

If you haven't achieved your goals, modify the content to comply with Google's guidelines.

Pages have underscores in the URL
Indicates that you have characters like “ñ,%20%,_” and others within your URL.

Which in principle can create an indexing problem, but it may not mean that you have one.

On many occasions I have seen URLs with poor structures that rank better within a domain than those that did follow Google's rules.

Before you start solving this warning, you should analyze whether the URL has SEO traffic or not.

If so, you should consider not taking any action (depending on your overall SEO strategy).

However, if you are not getting traffic from Google, you may want to consider creating a properly structured URL and doing a 301 redirect from the old URL to the new one.

This way, it won't lose whatever little value it had.

One recommendation for this type of warning is to complement SEMrush with the URL analysis provided by Search Console or another SEO tool.

It is always good to make sure before taking any action.

Pages don't have an h1 heading
Here it is telling us that within a URL there is no HTML - H1 tag and this should be treated as an error rather than a warning and I will explain why: H1 tags are one of the most important SEO factors since Google always values ​​it to see what SEO focus we want to give to a URL.

All URLs must contain this tag.

If we don't have the H1 tag, we are missing a great opportunity to tell Google in which direction we want to position a URL.

It may be forgivable if this tag is not present somewhere on our domain, but if it is not on the main page or home page it is an unforgivable mistake because the H1 on the home page helps to quickly position in niches that are not very competitive.

Now, you can go for branding or go for a keyword for your business model.
