1. Title / Description
For some they are too long, for others they are too short, for some they are absent, and for others they are duplicated. Both of these parameters are necessary for pages to rank correctly in search engines. A flaw or incorrect configuration can affect the visibility of the site.
2. Internal and external links
External links are not closed in rel="nofollow", internal links are closed in rel="nofollow". This parameter is important for conveying the weight of the page. In one case it is better to save it, in another it is better to transfer it to improve ranking.
3. Open Graph and schema.org markup
Empty fields for parameters or incorrectly entered values. Markup is necessary for the site to be displayed beautifully in search results and on social platforms. But it is often overlooked and can affect visibility.
4. X1
Duplicate H1s, no H1s, multiple H1s on the same page, or a mixed hierarchy of headings (H1-H6). Headings play a key role in ranking, and setting them correctly can have a significant impact on your site's search visibility.
5. HTTPS
Pages with HTTPS link to HTTP, mixed content, or insecure elements. Search engines prefer secure sites, so it is important that all pages on the site use HTTPS to ensure data security.
6. rel="canonical"
Missing canonical tag or pointing to another page in this parameter. This tag helps to avoid duplicate content and correct ranking of pages on the site.
7. 4xx (Server status code: 4xx)
Links to non-existent pages. Such links are not only useless for users, but can also negatively affect the SEO position of the site.
