Search engines have super-intelligent algorithms. They are complicated in a remarkable way. What do search engines do? Connects users with the information they are looking for. 

There is an amazingly large amount of information on the Web and much is added every day worldwide. 

How search engines display search results

We all used search engines without thinking too much about what was going on behind the scenes. We see results obtained in a few milliseconds. Search engines do this by analyzing words and content on web pages. They place special emphasis on words that appear in certain locations on the webpage such as title, subtitles, image attributes, general content emphasis, outbound and inbound links, and so on.

Each search engine can offer users a very different experience. There are several aspects that can be considered. One is the location of the user looking for something.

There are major differences depending on the geographical location. For example, search engines that are in both English and German languages provide both English and German descriptions for search results. It is amazing to think about how different people around the world will see the same search results presented in different ways, depending on the geographical region in which they live.

Social signals and search results

Increasingly, search engines are also looking at social media signals that contribute to the overall authority of the site. It even happens that a social page of a business is shown above in the search results compared to the page of the respective business. If a site is linked to Twitter or is mentioned on LinkedIn or Pinterest, this is just another signal that provides intuitive search engine cues about what this site is trying to convey.

Social media signals also help with online discovery, as you've probably seen on many of your favorite sites that integrate social sharing buttons. For example, you've been invited to share a webpage you've found on Facebook or Twitter.

Some search engines give more importance to social signals than others. Or others pay special attention to certain social networks.

Relevance and search results

When a searcher writes what they are looking for in the search field, the search engine tries to match those signal words and words from the large number of web pages it has analyzed.

Provides a list of matches that are organized by what the particular search engine recognizes from the most relevant to the least relevant. This does not necessarily coincide with what the user considers most relevant.

However, the sites at the top of the results are the ones that the search engine has ranked according to a wide variety of criteria. It also takes into account how many other people actually found that page valuable by clicking on it.

The vast majority of people who search for something through a search engine do not pass the first page of search results. In fact, studies have shown that the top five to seven search results are the ones that get the most clicks.

What is the conclusion? More clicks means more pageviews, more page views, more revenue, and greater recognition of authority in any area where the site may be placed.

Getting a search result on the first page is an optimal target for anyone who wants to have the product, application or website in front of people who are interested in it. This process is much more complicated than the subject of this article.

Search engines always rank results according to a complex set of factors that work together to bring searchers results that are as relevant as possible to what they are looking for. However, this process is not perfect.

We all know that there are times when our search results are completely useless and we must continue to filter and optimize our search queries to find what we are looking for. More than that we don't know yet why in most countries of Europe the search results are not often updated with new links. Or the content of SERP is totally different in the UK - mostly with text, vs. in the US - mostly with images, video, and text.

There are niche search engines that find what others cannot

Search engines to find content you can't find elsewhere

Niche search engines are tools designed to jump deep into the hidden or invisible part of web pages, which is not easily accessible through general search queries. These search engines will find content that you will not be able to find with generalized web search.

The following search engines focus on a wide range of content areas, books, medical information, images, books, mathematical information, etc. to discover resources you never knew existed.

Mathematics and scientific search engines

Whether you need to solve a complicated math problem or look for scientific discussions about eclipses, the following search engines can help you find solutions to a wide variety of mathematical and scientific questions:

- Wolfram Alpha https://www.wolframalpha.com/ - model your queries more efficiently and get hyper-appropriate results.

- Medical search engines such as PubMed, WebMD - you can find answers to your medical questions, to get more information on various health topics or just to learn something new.
