2. Broken Internal Links

This kind of error is exclusive to error 404. It occurs when users click on a link that sends them to a nonexistent page on a particular domain.

3. Pages without Unique Title

Page titles help users and search engines understand what the page of your website is all about, without having to go through the whole content.

When the title of a page is not unique, users and Google crawlers might find it somewhat complicated to distinguish it from other pages.

4. Page without Unique Meta Description

A Meta description is what helps to provide users with a short overview of any suggested webpage on SERPs. Most information-seekers do use their mouse and hover around the search engine results to get a clue of what a link is all about.

So, by creating a unique Meta description of your webpage, you are directly contributing immensely towards increasing your organic CTR.

5. Page with Links to HTTP Pages

Online users are mostly security conscious of some links. When a link on your webpage is pointing to a resource with a not-secure HTTP protocol, users may simply avoid your page.

This is also applicable to Google as well; it avoids such sites. The effect of this on your webpage is a significant decrease in SEO rankings.
