What elements should my web page have for good SEO?

I don’t know if you mean that there are pages that it indexes but doesn’t show (as it says that in Google Search Console), it’s like a subtle way of telling you that certain content doesn’t seem relevant to it, sometimes it works that if you upload a lot of content you it gives more visibility, but if you don’t have engagement it can take it away and it’s counterproductive, I assume you can also refer to that, it depends more on the user’s behavior, the results change frequently, so even if you do everything right, you shouldn’t be surprised that it takes away positions , but it is not necessarily due to the number of pages, if you mean the opposite case, sometimes you can get small pages first, they do not necessarily have to be thousands of internal pages, a microsite can be positioned, it depends more on other factors and how last case… I have a significantly smaller page than another, but it is easier for me to position something from there than from another huge one that I have with even more authority, on the other hand, when When a page is very varied in content, Google has a harder time identifying the theme, so in that sense it can affect you, but it is not precisely because of the quantity, but because of the variety.

There are many factors that influence SEO and the list would be very long, but here is a short list of things that you should take into account to start

Hosting and domain. Choose good hosting, with good RAM and storage. A domain that is aligned with your business or sector. Although the domain match no longer influences the positioning as before, it is important to take care of this aspect as well.
Web speed and usability: do not use very heavy pages or CSM’s with many plugins. At the same time make an intuitive website, with the elements strictly necessary for the user to interact and a simple and intuitive web map.
Align the content. Let your text talk about your business. Take care of the titles and meta descriptions.
Link, link and link: offer related content to users and try to get other websites that talk about the same as yours to also link to you.

Although there are many more factors to obtain a good SEO positioning, I think that if you meet only these 4 points, you will already be doing a good SEO, but of course, this also depends on more factors, such as how competitive your business niche is and the resources used by the competition for its positioning. I hope it helps. All the best!

SEO is about optimizing your content for search engines. What increases by receiving repeat visitors is your position in the SERPs or results.

Why? Very simple, if visitors repeat the search and search for your website among the results, this leads us to your website meeting the search intent.

Is search intent and SEO related? Yes, SEO allows us to know in advance the search volumes of certain terms. With these we make the content and respond to the visitor’s search intention or rather we try.

technical aspects (depending on you): loading speed, performance, avoiding broken links, taking care of redirects, robots, sitemaps, etc.
Content (depends on you): Select the keywords correctly, structure the H headers correctly and include the keywords in them, generate quality content that is well written and generates interest, include the titles correctly and include the keywords in them , avoid duplicate content, send thin Content, etc.
External aspects: Observe your competition, see what they do well and what they do badly. Draw a quality backlinks strategy, etc.
