Search engines are limited in the way they crawl the web, and in the way they interpret the content.
The way a web page is presented to search engines is different from how we see it. The search engines read and interpret codes and technical declarations, which are insignificant for us, but necessary for the correct interpretation of the web pages. In this post, we are going to deal with some technical aspects, useful for the generation and modification of the WEB pages. Important aspects for the search engine, in order to correctly interpret, store and manage web pages.
To get good rankings in the SERP, the most important content (text and images) should be in HTML format, while flash, Java applets and other non-text content are often ignored or devalued by search engine crawlers. However, more advanced methods of interpretation are available, for those who require greater formatting, or more advanced visual styles:
- For images it is always recommended to provide alt text , that is, images in gif, jpg or png format should always be accompanied by the alt attribute (HTML) to give search engines a textual description of the content of the image;
- The search boxes should be accompanied by navigation indications, and navigable links;
- Accompany the Flash or Java plug-ins with the descriptive text on the page;
- To index the video and audio content, it is necessary to accompany the multimedia contributions with a descriptive text.
How to go about seeing your site through the eyes of the search engine
If you don’t follow SEO guidelines for building web pages, you can have problems with indexing. For this reason I recommend checking with specific tools such as Google cache , SEO-browser.com and MozBar . With these software you can see which elements of your content are visible and indexable to engines. Here is an example of a page, how we see it and how the Google search engine reads it:
In this case we can note that the lively.it homepage, read from Google’s cache (right), does not contain all the detailed information that we see (left). This makes it difficult for search engines to interpret the correct relevance. how to index website on google
Through the Google cache, we can see that the images are not correctly characterized, this means that it is not possible to index the images.
It is advisable to check the content of the text, and use SEO tools to verify that the pages of your site are visible to the engines. This applies to images and, as we will see later, also to links.
Link structure indexable by search engines
Just as search engines need to read website content, in order to list pages in huge keyword-based indexes, they also need to read links to find related content. A structured crawlable link (which allows crawlers to explore the website’s paths) is essential to find all pages accessible and visible on the website.
Many websites make the mistake of structuring their navigation in ways that search engines cannot access, hindering their ability to access pages listed in the search engine index.
Let’s see how this problem can occur:
In the previous example, the Google crawler has reached page A and sees the links to pages B and E. However, even if C and D may be important pages on the site, the crawler has no way of reaching them (and not even knowing that exist). This is because there are no direct navigable links either from A, or even from B and E. For search engines these two pages do not exist!
Great content, effective and smart keyword targeting, marketing won’t make any difference if crawlers can’t reach your pages.
Anatomy of a link
Link tags can contain images, text or other objects, each of which provides a clickable area on the page, and users can click on it by moving to another page. These links are the original navigation elements of the Internet, known as hyperlinks. In the illustration above, the “<a” tag indicates the beginning of a link. The reference position of the link tells the browser (and the search engines) where the link points. In this example, the URL https://bloginnovazione.webonline.click is referenced. Next we find the visible part of the link for visitors, this part is called anchor text, and describes the linked page. In our example, the linked page is about the innovation blog, then the anchor text BlogInnovazione. The “” tag closes the link to limit the linked text between the tags and prevent the link from including other elements on the page.
