Search Engine Optimization - A Beginner's Guide (Updated 2026)

In March 2026, Google published a new documentation guide on how Google's crawlers work. The document is titled “Things to know about Google’s web crawling.”

• What does crawling mean?
  In short: crawling is the way Google "sees" the internet.

• Google has multiple crawlers
  Different bots handle different tasks.

• Google performs continuous recrawling
  This is how Google finds updates and can display the freshest search results.

• Frequent crawling is a good sign

• Crawling has increased over time
  Website structures have become more complex.

• Google optimizes crawling automatically

• Google does not go behind paywalls or subscription content without permission

• Site owners can control crawling
  For example, using the robots.txt file and other settings.

• Google's robots respect website settings
  They follow the rules defined by websites regarding content usage.

One of the key takeaways from the document is that frequent crawling of a site is generally a positive signal.

Google writes:

A good example of this is an online store. Google crawls online stores frequently so that up-to-date prices, offers, and stock status are shown in search results.

Why is this important?

Indexing is a fundamental prerequisite for search engine optimization (SEO). If Google cannot index your site correctly, your content cannot appear in search results.

The purpose of this guide is to help website owners understand:

• how Google's indexing works

• why pages are indexed at different frequencies

• what things can be done to improve the site's crawlability.

Google does not reveal much about how it works. However, here are a few recommendations from Google on how to improve rankings on Google.

Recommendations brought up to date: August 20, 2026

• NEW: The content must have a unique perspective. Google fights low-quality AI content by judging whether you bring a new perspective to the subject.
• NEW: Add your own experiences to the content. Google's spam update fights AI content by judging whether the content includes the writer's own experiences. AI has no experiences.
• Make websites for people, not for robots or search engines.
• Do not try to deceive users or show different content to users and search engines.
• Create a website with a clear hierarchy and text-based links. Every page on your site must have at least one text link. Search engines cannot use search forms.
• Write unique and information-rich text. Avoid spelling errors.
• Add images and videos to your pages.

In 2019, Google also published an official list of questions to evaluate whether a page is search engine optimized or not.

People use search engines for different purposes. These searches can be divided into three different groups.

1. Searching to do: I want to do something, like buy a plane ticket or listen to music.
2. Searching for information: I want to know when a band has a gig or what is the best restaurant in Tampere.
3. Navigation: I want to get to a specific place on the internet, like Facebook or the homepage of Iltalehti, a Finnish news site.

When a user types a search into a search engine, are they satisfied with the search results? This is a question that search engines try to answer millions of times a day. The main task of search engines is to provide relevant search results to their users. So ask yourself: What is my target audience looking for, and how can I deliver it to them?

What is my target audience looking for, and how can I deliver it to them?

Do a test: Search Google using keywords from your own industry and see what kind of content your competitors have written on their pages.

Before actual search engine optimization, it is a good idea to check what kind of searches your target audience uses to find your services. For this, use the Google Keyword Planner.

With the tool, you can test the search volumes of search terms and choose the right wording. To start, give the tool one or more search terms. The tool will then provide estimates of how much the term is searched for and suggestions for other similar searches.

Make a list where you write down a search term (as a keyword) for each page of your website under which you would like the page to appear in search engines. However, the best search term is not necessarily the one with the highest search volume. Choose a search term that you think will best reach your target audience. Also, remember to use the same search term only once per page. So, do not optimize two different pages for the same search term.

Always define a precise location. For example, if you aim to appear in the search for “Plumber Tampere”, but your website says “We do plumbing work in the Pirkanmaa region”. The search engine cannot connect Tampere to Pirkanmaa.

You can read more about keyword research in the article What is keyword research?

In the example below, the word “parturi” (barber) is searched for in Tampere significantly more than, for example, “kampaaja” (hairdresser). In this case, it might be wisest to optimize the page for the search term “parturi kampaamo tampere” (barber hair salon Tampere).

Page meta data consists of snippets of code intended only for search engines. Meta data can be used to define which words the page appears for in search results.

Contrary to popular belief, meta data does not directly affect search engine visibility. However, a well-tailored "ad copy" can influence how many people click on your link in the search results instead of a competitor's.

Meta keywords.
Google no longer considers meta keywords in any way. Bing still uses meta keywords to identify keyword spammers. Therefore, do not use meta keywords in your optimization.

Meta description
The description can be used to specify the text that appears in search results. If the description is missing, search engines will generate it from the site's content. Often, the text generated by the search engine is not a good "ad" for your link.

Include the page's search term in the meta description. This way, the words appearing in the search query will be bolded in the search results.

Below is an example search for “barber helsinki” (in Finnish, “parturi helsinki”)

The meta description can be a maximum of 156 characters! If the character limit is exceeded, search engines will cut the text off in the middle. However, try to use all 156 characters or slightly less to make the text look as appealing as possible.

The description text must also appear on the page! In the best-case scenario, the meta description is copied entirely from the page's text. If the description and the site's text are different, the search engine will ignore the specified description and decide it on its own.

Page Title (<title>)
The title does not actually belong to the meta tags, but it still affects the text visible in search results. Include the search term in the page title and make sure the title is at least 40 characters, but no more than 70 characters. A title that is too long will be cut off mid-sentence.

On WordPress sites, meta data and titles are easy to check with the Yoast SEO Tool.

Internal duplicate content on a website is also common. This means the same content is shown in two or more different places. Here are a few of the most common reasons for duplicate content:

1. Multiple URL addresses are set for the same page
   • Parameters. E.g., yourcompany.fi/service?color=blue, yourcompany.fi/service?color=red
   • There is a printable version of the page. E.g., yourcompany.fi/service and yourcompany.fi/print/service
   • Session IDs. E.g., yourcompany.fi/service and yourcompany.fi/service?SESSID=123
2. Two or more different domain names point to the website. E.g., yourcompany.fi and yourcompany.com

Search engines do not like duplicate content any more than they like copied content. Sometimes, the wrong version of a page might end up in search engine results.

Duplicate content can be easily fixed
Search engines have adopted a common HTML tag for this problem: Canonical. With the canonical tag, you can indicate to the search engine which version is the one you want to display in search results and which version is a copy. This way, the search engine ignores the copied content and only shows one version of the page in the search results.

WordPress users can easily use the Canonical tag with the Yoast SEO Tool.
Select the "advanced" section from the tabs and enter the correct version of the page or article in the canonical URL field.

Search engines have limited resources for crawling the internet. If your site loads very slowly, Google might not be able to index the site at all. Secondly, people also have a short attention span on the internet. Slowly loading pages affect user experience, which indirectly impacts search engine visibility.

Test your own site's loading speed with Google's own tool: https://pagespeed.web.dev/

The most important metric, "Largest Contentful Paint", should be a maximum of 2.5 seconds. Google claims that 50% of people won't wait for loading speeds of over 3 seconds.

Social media can be utilized in search engine optimization mainly by growing the company's and brand's reputation. Have a broad presence on social media channels where your target audience spends time. Share interesting content and gain followers. Over time, as your reputation on social media grows and people get to know your company better, they will start searching for you on search engines. This improves your search engine visibility.

Links from social media do not really improve search engine visibility.

By adding your business to Google's map service you will appear in the map listing when someone searches with keywords related to your industry.

Below is an example of a search for “katsastus tampere” (vehicle inspection). The businesses whose websites are at the top of the search results appear highest, i.e., in the best positions, in the map links. If your website has poor visibility on Google, your map link will also have poor visibility.

It is also recommended that you add your most important search term to your business name. For example, if you offer home cleaning services, write “Home Cleaning | Company Name Ltd” in the business name field in the Google My Business service.
