Your website users don't have much time and patience. Your job is to help them get to the right page as quickly as possible. To do this, ask yourself a few questions:
Which pages are the most important?
What actions are most often taken by phone visitors of the site?
Which pages most effectively meet the needs of the mobile user?
The answers to these questions help you to understand not only what elements should be added to the main menu, but also what links and calls to action should be placed on each page.
The main thing is for the navigation menu to be uniform throughout the site. Here you should specify several top pages (e.g., main categories).
Short-term mobile navigation is a win-win for SEO and usability. It helps users navigate better and keep traffic flowing to other, lower-priority pages.
Contextual links can be added to the main content of each page in many ways. For example, when publishing a longread on a blog, you might place a block at the top with the content and anchor links to the main sections of the article. This is not just convenient for the reader, but it also helps search engines better identify pieces of your content that meet certain search queries.
Another option is to add useful calls to action and links to related pages at the bottom of the page or in the body text, where it might be appropriate.
