Your website has to have an acceptable appearance over various devices, and that's another feature that will rank your SEO up. Mobile-friendly pages have the priority for google bots to give more attention.
Have you seen the special box appear when you search particular keywords on the google search bar?
You certainly have seen boxes that reverse the regular search result format, showing the descriptive snippet before any other results. They are called google feature snippets. Google bots will put your website data into the particular snippets if they recognize it, and that will happen if your data is structured.
Data structuring is involved with programming and providing the proper templates into the HTML tags. Structured data has many forms like Recipes, various movie genres, events, countries, cities, or the top places to go or things to try.
To sum up, by paying attention to these factors and improving them, Crawling can gather more useful information over your website by having device-friendly pages, a good site navigation system, and linking your pages correctly. Indexing takes place more adequately by having short and meaningful page titles, coherence between the website's sections, and annotating your video and images with alt texts. So, your website will be ranked and served so much better. That means when users search their keywords, google tries to find the most relevant answers based on mentioned factors. And your website will be among those.
