In today’s digitalized society, statistics show that an average number of people spend 3 hours and 15 minutes online every day, while 1 in 5 smartphone users spend 4.5 hours on their phones daily. This statistic is why smart businesses take online representation seriously.
In a 2023 survey, according to Forbes, 71% of businesses were recorded as having a website. However, for businesses, having a website or an online presence is not the ultimate solution to getting customers. The question is, How can you beat competitors in the same market and come up top as the highest-ranked business in your industry when users perform a search?
Businesses are consistently seeking ways to optimize their web pages. Ranking high in the search engine result pages [SERP] is possible if you understand how to use Search Engine Optimization [SEO] to your advantage.
SEO (Search engine optimization) is an important concept for website visibility. It’s a common term used for online businesses. When working with content, Search engine optimization [SEO] enhances the user experience, among many other reasons that we'll briefly highlight. Your website needs to be Search engine optimized to achieve growth and sustainability.
To make it easy for the search engine bots to crawl through your most important pages, there’s an important component of search engine optimization called the robots.txt file that serves directions. In this article, we’ll discuss how to utilize robot.txt files when working with a WordPress website.
Prerequisite:
We assume that you’re familiar with the WordPress content management system that helps users create websites easily; therefore, we wouldn’t be discussing the purpose of WordPress.
Here’s a link to our WordPress article to get you started with WordPress as an absolute beginner. . Before we dive in, we’ll go through a brief understanding of what a Robot.txt file is and then discuss how to implement it on a WordPress site.
What is a Robots.txt File?
The Robot in Robots.txt refers to software programs or bots, also known as web crawlers, deployed by search engines to crawl website pages you want to index. Examples of popular web crawlers include, e.g. Googlebot, YandexBot, Bingbot, DuckDuckGo, etc.
A robot.txt file is a file name for implementing robots exclusion protocol, which is a standard used by websites. It’s like a set of rules, and it’s a file that contains instructions that tell the search engine crawlers and web robots which URLs to access or avoid on a website.
When a new website is created, search engines send crawlers to collect the information required to index the webpage. The crawler collects information like keywords and web content and adds it to the search index. When a user performs a search, the search engine fetches the necessary information from the indexed website.
A common website where a robots.txt file is recommended is an e-commerce website. On an e-commerce website, users typically perform a search to filter through products. Every search or filter will create multiple pages on the website that will eventually increase the crawl budget (the number of pages or URLs a search engine can crawl on a website over time). This may cause search engines to ignore certain pages on the website because they are crawling irrelevant pages.
Without the robots.txt file, search engine robots will index all accessible pages and resources on your website. This may include file directories, images, pdf, excel sheets with the users' information, etc.
If you don't have a robots.txt file, too many bots might end up swarming your website, and that could seriously slow things down. But here's the catch: not every website actually needs a robots.txt file. It all depends on what your website is all about and what you want to achieve.
What is the Benefit of Using a Robots.txt File for Website Optimization?
There are several benefits to using the robots.txt file, and they are:
Content Control & Privacy
Structured Indexing
Enhance SEO
Improve User Experience
Manage External Crawlers
Content Control and Privacy: The robot.txt file is used to specify the parts of a website that should or should not be crawled by search engine bots. This could be a file path or URL parameters.
Structured Indexing: The robots.txt file specifies pages that should be crawled and indexed. Instructions are given to search engines to index a website in an organized manner, making it easier to find relevant web content.
Enhance SEO: The robots.txt file optimizes or improves the performance of a website's SEO by preventing the indexing of web content that is not relevant when a user performs a search query.
Improve User Experience: Robots.txt file can enhance user experience in several ways, which may include; preventing crawlers from indexing duplicate content or blocking search engine crawlers from accessing file directories e.g. scripts etc.
Manage External Crawlers: The robots.txt file controls the behavior of other web crawlers by instructing the bots on whether they can crawl or index the website's content.
Crawl Delay: Robots.txt file prevents servers from being overloaded by search engine crawlers with multiple contents simultaneously.
Deconstructing the Syntax of robots.txt Files
Let’s break down the syntax of the robots.txt file, which is the key to controlling web crawler access and optimizing website visibility. Through this, we will be shedding light on its significance in shaping a website's interaction with the virtual world.
User-Agent: This is used to call out specific search engine crawlers. The search engine crawler initially searches for the robots.txt file located in the root folder of your website before beginning to crawl. It’ll search the text file to see if it’s being called. If it is, it’ll read whether it’s allowed to access or not.
Disallow Rule: This tells the user agent not to crawl certain parts of a website. You can apply as many “disallow” rules as you like, but you cannot add more than one command per line.
Allow Rule: Allows the user-agent access to a page or its sub-folders even if the parent folder is disallowed.
Crawl Delay: This tells the crawler to wait for some seconds before loading and crawling pages on a site.
Sitemap: This tells the search engine crawler where the XML sitemap is located.
/ (forward slash): This is the file path separator.
(Asterix): Represents a general rule that affects all user agents or everything related to certain criteria.
#: This represents comments
$: This specifies the rule that follows after it is applied to a particular user agent.
In this example, we’ll be looking up the Alibaba.com robot.txt file. Different rules can be set based on what your site needs, in this case, the rules have allow and disallow directives followed by a directory/directories.
