The main goal of a search engine’s algorithm is to give users the best search results. It looks at many details on web pages to see how relevant and good they are. This helps users get the best answers to their searches.

When you search for something, the algorithm tries to understand what you really want. It looks at things like the words you used, the type of content, how new it is, and if people like it. These factors help decide which pages show up first in your results.

Its mission is to match what you’re looking for with the best information. Understanding these algorithms makes search engines better at showing what you need when you search. This makes searching online a better experience for you.

By aiming to understand your search, search engines connect you with what you need faster. Website owners use SEO to make sure their pages meet the algorithm’s standards. It’s important for both searchers and website creators to know how this all works.

What happens when a search is performed?

When you search for something, the search engine starts working to find what you need. It looks at its index – a big list of web pages – to find matches for your words.

Then, the search engine ranks these pages. It looks at things like the words on the page, how good the info is, and how often people visit the page. This helps it make sure the best pages come up first in your search results.

After ranking, the search engine shows you a list of pages that are related to your search. You get to choose which one to click on and learn more about.

When you click on a search result or stay longer on a page, it tells the search engine what you like. This feedback helps the search engine get better at showing you what you want.

Search engines are always working to show you the best results. That’s why the order of the pages might change, as the search engine gets smarter to meet your needs.

Why might a page not be indexed?

Several reasons could lead to a page not being indexed by a search engine.

  1. If the page is excluded from crawling by directives in the robots.txt file.
  2. If there are directives on the page itself, such as the noindex tag or the canonical tag pointing to another similar page.
  3. If the search engine algorithms judge the page to be of low quality, containing thin or duplicate content, or having other issues.
  4. If the URL returns an error page, it may not be indexed.

Making sure your pages can be indexed is key. This helps them meet the search engine’s quality rules. By dealing with issues about indexing, website owners can up their chances of showing in search results.

Reasons why a page may not be indexed
ReasonDescription
Exclusion by robots.txt fileThe page is explicitly excluded from crawling by directives specified in the robots.txt file.
Directives on the pageThe page contains directives like the noindex tag or the canonical tag pointing to another page.
Low-quality contentThe search engine algorithms consider the page to be of low quality, with thin or duplicate content.
Error pageThe page’s URL returns an error page, preventing it from being indexed.

How do search engines make money?

Search engines get money mainly through ads. Businesses can pay to show their ads on the search results page.

These ads show up above or next to the regular results. Companies choose specific words so their ad pops up when someone searches for those terms.

This model helps search engines earn. At the same time, it lets companies find their customers better. For users, it means finding what they want more easily.

Benefits of advertising on search engines:
Increased visibility: Paid search results appear prominently on the SERP, increasing the likelihood of users seeing and clicking on the ads.
Targeted audience: Advertisers bid on keywords specific to their business, ensuring their ads are shown to users actively searching for related products or services.
Measurable results: Advertisers can track the performance of their ads through metrics like click-through rates (CTR), conversions, and return on investment (ROI).
Flexibility: Advertisers have control over the budget, ad copy, and targeting options, allowing them to optimize their campaigns for maximum impact.

How search engines rank pages

Search engines use hard-to-understand formulas to figure out who shows up first when you search. They look at many things like how often certain words appear, the quality of information, and how people interact with a website.

They also check if a page’s topic matches what someone is looking for. Pages using the right words in their titles and content might show up sooner in your search results. Quality is a big deal too, and search engines love pages with original and helpful info.

When people click on a page and stay awhile, search engines think that page must be pretty interesting. They see this as a sign that a page is useful. A website’s reputation and how long it’s been around also matter, telling search engines if a site is trustworthy.

Getting links from other sites is like getting a thumbs up. The more thumbs up from reliable sites, the better a page might do in searches. Each search engine does things a bit differently, so the same search might show different results depending on where you look.
