Search engines work by gathering and categorizing information about web pages through crawling, indexing, and ranking. These search engines then return the most relevant pages in response to a user’s search query based on the information gathered through crawling webpages. How search engines work: Achieving user satisfactionHow search engines work seems impersonal and technical, but that’s not the goal of search engines. Search engines aim to provide helpful content that answers a user’s question, whether they’re wondering how tall Mount Everest is, where to find tonight’s dinner, or the URL of Apple’s website. That’s why search engines like Google use more than 200 ranking factors, including:
It’s also why search results continue to evolve as search engines grow their indexes and users shift their preferences. How search engines work: Personalizing search resultsSearch engines rely on more than their index to generate search results — they also rely on users. With information like a user’s location, preferred language, current device, and even search history, search engines like Google can deliver highly relevant results. For example, someone searching for “sushi near me” will see search results based on their location, like sushi restaurants in Los Angeles, California. In comparison, someone searching in Houston, Texas, will see a list of sushi restaurants in that area. How search engines work: Generating search resultsYou know how search engines work at a broad level, but what happens when someone makes a search? The step-by-step process is as follows:
The process doesn’t stop here, though. Search engines like Google also monitor how users interact with search results. If someone visits a website from the search results but then returns, that registers as pogo-sticking, which can signal that a search result isn’t relevant. Depending on how often this happens, Google may adjust its results for “how to tie a tie.” 7 reasons your company’s website doesn’t show up in search resultsIs your company’s website still missing from search results? Check for the following issues, which are some of the most common culprits for indexing issues:

How search engines work for your business in 2021In 2021, search engines work using web crawlers and advanced algorithms to crawl, index, and organize the web’s information. The process revolves around web crawlers, which crawl pages that the search engine adds to its index and then organizes and delivers to users via its search algorithm. That’s an overview of how search engines work, but how do they work for businesses like yours? Search engines serve as one of your company’s best team members because: With a search engine like Google, your business can capture more traffic, which translates to more leads, sales, and revenue when you optimize your website for the kinds of searches your target audience makes when moving through the modern-day buying funnel.

Or, keep reading to learn more about what search engines are and how search engines work! What are search engines?Search engines are the primary tool people use to access websites and pages on the Internet. Without search engines, you could only find web pages by following a hyperlink or knowing the exact URL. With search engines, discovering the answer to “What is EVOO?” is as simple as typing the question (it’s an acronym for extra virgin olive oil, by the way). The five most popular search engines today are:
These search engines all work in similar ways, but we’ll focus mainly on the most popular search engine, Google, for this page. How search engines work: Inside the 3-step processIf you’re looking to understand how search engines work in-depth, then read this section. You’ll get an inside look at the three-step process that makes search results — and using search engines to drive revenue — possible. 1. CrawlingFirst, search engines work by crawling publicly available pages on the Internet. Search engines use web crawlers (also called bots or spiders) to find these public web pages and eventually index those pages. Web crawlers work by:
The web crawlers use that information to decide whether to add that page to the search engine. They also list all the links on the page and queue the pages associated with them for crawling. Web crawlers don’t just crawl a page one time, either. Instead, web crawlers work non-stop to crawl and recrawl the uncountable number of web pages on the Internet. Doing so allows search engines like Google to have the most up-to-date versions of the pages. Additionally, spiders have crawl budgets. A crawl budget, simply put, is the number of pages on your site spiders crawl through and index before leaving, as well as which pages get crawled. Crawl budgets take into account the limit Google sets on how often to crawl your site (based in large part on how frequently it’s updated and its popularity). Google puts a limit on the number of pages crawled in one sitting to lighten the load on servers. If spiders scrape your site too fast or too often, it can bog down your servers, especially if your site contains thousands of pages. 2. IndexingAfter the web crawlers work to read a page, they process and submit the information into an extensive database called a search index. Search engines each create an index of online pages. Google, for instance, doesn’t rely on Bing’s index to generate search results. The index works similar to a library catalog. It’s a massive list of categorized entries that include all the information that crawlers scraped from the web. Each page gets an entry so search engine algorithms have easy access to its contextual information. Using their massive indexes, search engines like Google quickly and accurately locate pages with relevant information. 3. RankingAfter the indexing phase comes ranking. Search engines show results to users when they search but search engines can’t show all the pages it has in its index. Instead, it must choose which pages to place in results and the order in which these listings appear. Search engines must then use the index’s information to accurately pull search pages with relevant information to show in searches. They also must determine how those pages rank according to relevance. This problematic and arbitrary task is made easier with strict factors defined by search engine companies. These factors help search engines determine page relevancy. These algorithms determine relevance by looking at:
Ranking involves more than just keyword selection and backlinks. Other factors focus on user experience, which strongly impacts how Google ranks search results. These factors include:
Google takes all these factors into account when ranking your site. Google’s algorithms use incredibly advanced artificial intelligence, which is adept at identifying what people want to see when searching. Google BERT, for example, was an algorithm update Google performed in 2019. The update focused on improving the algorithm’s ability to understand what people mean when they enter search queries. Through machine learning and natural language processing, BERT can better understand the context of all the words in a search query. With the update, Google can more easily understand things like synonyms and misspellings. Why does getting crawled, indexed, and ranked well by search engines matter?Less than 50% of businesses use search engine optimization. That’s surprising because getting crawled, indexed, and ranked well by search engines is critical to growing a company, whether a startup or an enterprise, in 2021. When you exclude search from your marketing strategy, you exclude yourself from valuable leads, sales, and revenue. Here are a few reasons why — and how — search engines generate business growth: Buyer journeys happen on search enginesMore than 90% of online experiences start with a search engine, which means when someone wants to find a new barber, upgrade their coffee machine, or get proposals for their company’s next project, they turn to a search engine like Google. Even if your transactions happen offline, people use search to discover businesses in their area. Research shows that four in five consumers use search engines to find local information. Not to mention, 76% of people who make location-specific searches visit a related business within a day, which is one reason 80% of local searches convert. Search engines maintain an impressive close rateSearch engines help people discover your business, making it possible for your company to nurture more leads and close more sales. Compared to traditional marketing close rates, search offers a massive improvement with a 14.6% close rate — traditional marketing’s close rate is less than 2%. Traditional marketing frequently fails against digital marketing strategies like SEO because SEO:
Essentially, with search, you can reach your dream customer at the right time with the right content. That perfectly timed connection makes a significant difference in capturing more leads, sales, and revenue. Search engines connect your business with its target audience 24/7People search around the clock. That’s why search engines serve as fantastic team members. With search engine optimization, your company can capture valuable traffic 24/7, without the cost of overtime. Instead, your website serves as a hub for potential clients to learn about your business, contact your team, and even purchase your products — if you maintain an ecommerce site. How to get your company’s website crawled, indexed, and ranked in search resultsYou know how search engines work, as well as what a search engine does, but do you know how to get your company’s website crawled, indexed, and ranked in search results so you can capture all the benefits of SEO? If not, check out this walkthrough! How to get your company’s website crawledHaving your site crawled is the ticket to Internet visibility. You want to make sure that spiders can easily access your site because your site needs to get crawled before it can ever appear in search. It’s as simple as:
If you have a new website (or even a new page on your site), there are a few tricks you can do to get Google to crawl your site quickly: Submit your URL to Google Search ConsoleYou can request a crawl from Google by submitting your URL in the Google Search Console. Providing your URL allows Google to find your site faster. You can submit your URL by heading to the URL Inspection tab in your Search Console account. Then select the “Test Live URL” option and click “Request Indexing” if the test shows your URL hasn’t gotten indexed. Include internal links in your new page to older content (and vice versa)Internals links are hyperlinks you place on your pages that link to other pages on your site with relevant information. Internal links help spiders crawl your site by allowing them to travel from page to page more quickly. When internal links link to relevant content on your website, it can help Google better understand the context of your content. In the same way, internal links also help your visitors navigate your page and find additional content. Create an XML sitemapYour XML sitemap contains information for Google on how often it should crawl individual pages on your site. For example, let’s say you have a page for your blog and a page for FAQs. Your FAQs don’t change much, but your blog gets updated daily. Within your sitemap, you can tell Google that you want it to give your blog priority over your FAQ page. Sitemaps also help spiders find and understand the level of importance you give the new pages you publish. You can request a crawl of your site by submitting your sitemap to Google’s Search Console, as well. You aren’t limited to one sitemap, either. You can have multiple, such as a central sitemap and a sitemap for your blog. Create a robots.txt fileYour robots.txt file is a list outlining suggested crawling instructions for Google and other crawlers. This file, however, doesn’t control what search engines index or how they do it. Robots.txt just lets Google know you’re preferences towards crawling individual pages on your site. There may be some cases that you would want to suggest an opt-out on having particular pages on your site crawled. For instance, if you run an online store, you probably wouldn’t want Google to crawl your customers’ accounts. Or, if you happen to have multiple URLs for the same page on your site, you want Google crawling the page only once. Limiting the pages that get crawled also helps your site manage which pages count towards your crawl budget. In your robots.txt file, you can choose which pages on your site allow or disallow crawling, though search engines can still index your pages if someone else linked to your page. You can even limit crawling by identity. So, if you didn’t want Bing to crawl a page but wanted Google to have access still, you would put it in your robots.txt file. You can check how your robots.txt file looks by typing it after your domain name like this:
How to get your company’s website indexedHaving your pages indexed is a requirement for Google to rank them in search results. If your pages aren’t indexed, they won’t do you very much good since people won’t find them. Your pages won’t pull in any traffic. If you do not see your page on search, you can check out these simple search engine indexing strategies: Check if your page is indexed using the “site:” operatorYou can check all the pages that Google has indexed by conducting a “site:” search for your URL. Just type in “site:[your site domain name].com” into Google’s search bar, and it will pull up all the pages that Google has on your site. You can also perform a “site:” search to find content on your site that matches specific keywords, which is useful when looking to see if Google has indexed a particular page. The format goes “site:exampleurl.com example keyword.” Crawling and indexing generally take a few days, so don’t be too worried if your recently published page doesn’t immediately show up in search. Check your page’s status in Google Search ConsoleIf it’s been a while and you’re still not seeing your pages using the “site:” search operator, it’s likely that your site is not in the search engine’s index and probably hasn’t gotten crawled yet. You can double-check your page’s status using the “Test Live URL” option under the URL Inspection tab in your Search Console account. If your page hasn’t gotten crawled yet, you can request indexing. This process may take a few days to accomplish. Also, check to see if there is a reason that Google isn’t indexing your content. Some problems that could prevent indexing include:
Check if you’re directing Google to not indexLike crawling, you can direct Google to not index pages on your website, such as admin pages and internal search. To do so, you can either include a “noindex” tag in your robots.txt like this:
Or include the “noindex” tag in the HTML of your page like this:
In some cases, these specifications could be what is causing your page not to be indexed when you want it to be, so be sure to double-check. How to get your company’s website ranked well in search resultsBy ranking pages, Google helps people find the information they’re looking to find. Search engine ranking means a couple of things to online sites. Your rank in search is a huge determiner for how much visibility your content gets. Take a look at these three stats: If your page doesn’t rank on the first page, you’re getting slim pickings for search traffic. Not having a high rank in search doesn’t just lower the traffic you get — it also decreases your ability to drive sales and conversions. Rank also indicates to your audience your brand’s authenticity. The more you rank for various keywords, the more authentic people will view you. Here are some strategies to improve your site’s rank in search results. Perform keyword researchKeyword research allows you to provide the most relevant content to your users, which helps you rank higher in searches. Take some time to study what users mean when they enter keywords into search engines. You can do that by researching what content currently ranks for the keywords you are targeting because Google’s algorithms do a good job of understanding what people want to know. When performing keyword research, make sure to target long-tail keywords. Long-tail keywords are longer phrases, often three words or more. They can include locational keywords like “near me,” question keywords like “what is” or “how,” and conversational keywords from voice search. Long-tail keywords work well for ranking in search results because they’re less competitive to rank for than short-tail keywords while still generating most of your site’s traffic. Build a link building strategyYour link building strategy involves techniques that encourage other sites to link to your site. Much of your link building strategy will center around producing content that your readers find valuable. If you create good content, people will be more willing to link to it. Other link building techniques include:
Make your content user-friendlyYou want your audience to enjoy the time they spend on your website. User-friendly content acts as a significant factor in the definition of valuable content. Google ranks search results with user-friendly content higher, and users will spend more time on your site. Make your content user-friendly by:
