If you own a website or blog you should at least understand the basics of online marketing. SEO is simply how you make your blog or website discoverable by Google, Bing, and all the search engines. Below we outline how a search engine works.

Search engines are classified into 3 categories

Human-powered directories

This works very similarly to the old yellow pages phone book. A search directory is an online categorised index of websites. These are human-focused as you submit your site to a directory and you have to wait till a human inspects and lists it.

Yahoo is an example of this. You submit your website and wait till they list it. It can take many weeks for a person to get round to looking at your site and giving it the go-ahead to go live on their directory.

It is important to note that search engine crawlers like Google will look through and use these directories.

Crawler based search engines

Google and all the main search engines work by sending out bots or spiders to crawl hundreds of billions of web pages. The search engine explores the web and indexes the pages and links it finds.

Crawlers have two parts

One, they scan the webpages, gather the data and follow the links within the website. They also revisit the website on a regular basis to see what changes you have made.

Two, now that the data has been gathered they will index your website and all its content. This will be updated regularly as new data is gathered from your website’s new content and updated information.

Hybrid search engines

Hybrid search engines use a combination of both directory results and crawler results. Sometimes you have a choice to search for something from the web or from the directory.
Finally …..

Display search results

A search result is simply the result of something that you searched for on the web. You will see all the page results listed and the order of these results displayed are the rankings.

Search engines use algorithms to decide and control the order of a web page and its rank. Different search engines use different algorithms, which is why you will often see different results and ranks for the same search topic across multiple search engines.
Algorithms are designed to order the pages by relevance and provide the most relevant pages on the first page of a search engine. From time to time these algorithms change, due to new software, ai advancements, and technical improvements.

Thank you very much. I think that advertising on the Internet is very important for any business. I do not know how to set up advertising companies on my own and I want to find a helper who will do advertising on yandex for me. What company do you think will help me with this?

Advertising is very important for business. I'm currently considering a promotion to Reddit. I am not an expert in such matters, so I turned to https://reddit-marketing.pro. It is better not to joke about the reputation because it can be lost quickly. I advise you to turn to them for help and enjoy the process.

Hmm, some marketers, like Steve Jobs, have fundamentally changed the business world as we know it. Others, such as Frederick the Great, have influenced how we understand consumer behavior today.

Advertising is often an effective thing. I love to advertise on Facebook and recently came across ad tracking companies on this site. This was advised to me by my friend, he said that with the help of their software, you can easily track how your advertising works. It turned out that my advertising is often very effective.

Search engines work by using complex algorithms to crawl, index, and rank web pages based on their relevance and quality in response to user queries. Here's a simplified explanation of how search engines work:

Crawling: Search engines employ automated programs called crawlers or spiders to browse the web and discover web pages. Crawlers start by visiting a list of known web pages and follow links on those pages to discover new ones. They collect information about the web page's content, structure, and links during the crawling process.

Indexing: After the crawling phase, search engines organize the collected information in an index, which is essentially a massive database of web page data. The index includes details about the content, keywords, and other relevant information from the crawled pages. This step allows search engines to quickly retrieve relevant information when a user performs a search.

Ranking: When a user enters a query into a search engine, it processes the query and matches it against the indexed data. Search engines use algorithms to determine the relevance and quality of web pages in relation to the query. Various factors influence the ranking, such as keyword usage, content quality, user experience, backlinks, and more. The search engine then returns a list of results ordered by their perceived relevance to the user's query.

Displaying Results: The search engine presents the search results to the user in the form of a search engine results page (SERP). The SERP typically includes a mix of organic (non-paid) results and paid advertisements. The organic results are ranked based on their relevance and quality, while paid advertisements are typically labeled and displayed separately.

Iteration and Improvement: Search engines continuously refine their algorithms to provide the best possible results to users. They analyze user behavior, click-through rates, bounce rates, and other metrics to evaluate the quality and effectiveness of their search results. Based on these insights, search engines make updates and improvements to their algorithms to enhance the accuracy and relevance of search results.

It's important to note that each search engine has its own unique algorithms and methods of ranking web pages, with Google being the most prominent search engine globally. Search engine optimization (SEO) practices aim to optimize websites to align with search engine algorithms and improve their visibility in search results.
