Search Engine Optimization (SEO) refers to the field of computer science and graph theory encompassing the analysis of updates and traffic fluctuations in search engines and all activities aimed at improving the crawling, indexing, and ranking of information or content on a website by search engine crawlers (also known as bots)—such as Google, Yahoo!, Bing, Yandex, Baidu, etc. In order to improve (or maintain) the position on the search engine results page (SERP) and provide the user with the most accurate search result possible for a specific search intent.

General description:
SEO optimization techniques make it possible to improve a website’s search engine ranking and, consequently, increase organic traffic volume. SEO also focuses on creating multimodal content that enables search engines or answer enginesleveraging various algorithms—to provide users with the most accurate result for a query or prompt (referring here to systems featuring AI-integrated search snippets, such as Google’s AI Overviews or OpenAI’s SearchGPT).
SEO optimization can be complemented or integrated by search engine differentiation—a strategy aimed at increasing direct traffic. Organic results appearing at the top of the SERP (the most relevant and accurate ones) are more likely to be seen and, consequently, clicked on by a higher percentage of users compared to those appearing in the middle or lower sections of the page.
Most search engines rely on complex software and hardware architectures that continuously generate rankings of results and answers by combining various search algorithms and validation systems (both manual and automated). Answers appearing in the top position, within search snippets, or in specific blocks (such as AI Overviews) represent the most precise results.
SEO activities are diverse and can be categorized into “on-page” (conducted on the webpage itself) and “off-page” (activities involving elements external to the site); they rely on an extensive list of ranking signals known as “SEO factors.”
Key SEO activities include the optimization of:
-
- web servers
-
- meta tags
-
- structured data
-
- JavaScript and CSS
-
- code strings and W3C validation
-
- site structure and navigation menus
-
- on-page text content and images
-
- internal site links
-
- site usability
-
- accessibility of information for search engine crawlers
-
- source code
-
- backlinks (links from external sites)
-
- images and videos
Search engine optimization involves various technical operations performed on the site’s HTML, CSS, and JavaScript code and content, as well as on the web domain’s overall hyperlink network within search engine indices. The quality and quantity of hyperlinks from other web domains pointing to a specific domain are crucial factors in determining that domain’s ranking. Consequently, off-site activity typically carried out through link-building techniques (such as guest posting) is also essential.
Search Engine Optimization (SEO), together with Search Engine Advertising (SEA), is part of a branch of internet marketing known as Search Engine Marketing (SEM). SEO differs from SEA in that its goal is to position a website’s pages within organic search engine results pages (SERPs) rather than in spaces allocated for pay-per-click results (paid advertising campaigns). Furthermore, SEO activities yield results over the short, medium, and long term—depending on the ranking difficulty posed by the number of competitors—whereas the effects of pay-per-click are instantaneous. Generally, organic positioning carries greater scientific and academic weight than paid results (which are commercial in nature): rigorous algorithms and validation processes determine the most correct and accurate answer for a given query.
The professional specializing in search engine optimization is known as an SEO specialist. SEO specialists work closely with other web marketing professionals—such as developers, graphic designers, social media marketers, and paid advertising experts—roles that are rarely combined within a single individual.
Google Optimization:
In the early 2000s, the Google search engine introduced a novel element to the challenge of web indexing: PageRank, an algorithm for evaluating page relevance based on mathematical concepts. Today, it is considered just one of many parameters to take into account (though not the most important one). Robert Metcalfe (inventor of Ethernet) described this algorithm in terms of the “network effect”: a network becomes more useful as the number of its users increases. Google indexes a page based on its content and the links pointing to it. Furthermore, it utilizes 200 secret metrics (or at least most of them are secret) that interact via the Google algorithm to determine quality and various other factors within sites (including blogs and other useful web services). To achieve top-tier Google optimization, a site must be “SEO-friendly”—meaning it is easily readable by search engine bots. This is accomplished by paying close attention to the elements found on every webpage and within every document uploaded to the web. Over time, Google’s original PageRank concept has been superseded by TrustRank—a more complex index—although, to date, there is no way to measure it directly in relation to a specific website.
Search Everywhere Optimization (SEO or SEvO):
Search Everywhere Optimization (SEO or SEvO) is an advanced SEO strategy that extends beyond traditional search engines like Google, aiming to enhance content visibility across various digital platforms—including AI systems, social media, video channels, and voice search technologies. This approach focuses on understanding search intent, personalizing content, and strengthening brand authority across multiple channels.
The emergence of Search Everywhere Optimization reflects the evolving digital landscape, where platforms such as YouTube, Amazon, and voice assistants have become vital search hubs, necessitating a more integrated and multifaceted SEO strategy. Furthermore, the rise of AI-generated content has raised questions regarding the authenticity and reliability of search results, underscoring the importance of SEO strategies that prioritize authentic human voices and high-quality content.

- Regarding individual pages, part of the optimization process involves ensuring that:
the page code is formally valid. Consulting WCAG specifications can be useful for making content more “accessible,” including to crawlers;
HTML tags (e.g., title tags, meta descriptions, alt tags, headings) are as relevant as possible to the page content (ideally incorporating LSI—Latent Semantic Indexing—keywords); In 2009, Google, Bing, and Yahoo announced that they no longer use the “keywords” meta tag for website ranking
…positioned and discoverable by search engine crawlers. Image search is the second most common type of search on Google. To achieve this, the image must have a URL that describes its content (e.g., /images/mobile_rosso.jpg) and a descriptive Alt tag (the text that describes the image). Additional information can be included in the Title and Caption fields (a caption serves to describe the image and is utilized by major CMS platforms). Leading image-focused web applications can populate these fields using the corresponding EXIF data;
page loading times must be good. Since search engines place great importance on this aspect, it must be a priority for a skilled SEO specialist, who will make code adjustments (such as reducing lines of code, particularly in CSS and JS), implement caching systems, and set up a Content Delivery Network (CDN). Finally, they will compress the images; unlike images intended for print, web images should not have excessively high resolution or large file sizes. If specific requirements prevent image compression, the user should at least be able to open large images on a separate page containing only that image—a common practice among websites that distribute wallpapers;
parameters are not indexed—for example, in server-side applications where a query is inserted into the page URL (i.e., parameter=value pairs appearing after a question mark following the page address, such as http://www.sito.it/path/page?parameter=value). Some search engines will download and index only the base page, ignoring the query. Furthermore, if the query contains specific session information (such as Session IDs, which change for every visitor), even Google fails to obtain a unique URL for the page, potentially leading to various negative conclusions. Cookies should be used for this type of information;
non-HTTP redirects are implemented via <meta http-equiv="refresh"> tags, as search engines may not necessarily follow them. There is also a widespread belief that their presence can negatively affect a page’s Link Analysis Ranking. Instead, all redirects should be implemented using HTTP redirect responses (3xx codes); moreover, any redirect performed via a <meta http-equiv="refresh"> tag violates sections.
content presented to the user and to crawlers should not be differentiated (cloaking) by attempting to recognize the user-agent string or the IP address of the bot scanning the pages. This is a potentially harmful practice that—in extreme cases—poses a real risk of removal from search engine indices and, in most other cases, results in a failure to properly leverage a site’s internal pages; if this is not possible for technical reasons (for example, providing static content for a site built entirely in Flash) but content staticization is required, it is preferable to handle it client-side using session cookies;
robots.txt and sitemap.xml files should be correctly implemented to instruct search engine crawlers on which content to index and which to exclude from the indexing process;
server performance must meet visitor needs regarding speed and accessibility;
Core Web Vitals—key metrics identified by Google to define the quality of a web page from a user experience perspective.
…content is not duplicated. Matt Cutts (former head of Google’s Webspam team) states that 25–30% of all web content is duplicated. As he himself has noted, content duplication can be a penalizing factor; however, there is currently no algorithm that actually imposes penalties for this type of activity. SEO efforts focus on removing such content or fixing the code errors that generate it (e.g., errors in pagination or dynamic variables). One strategy to avoid duplicate content on a site is to include a canonical tag on the page.
