To put everything in context, Search Engine Optimisation (SEO) has become quite advanced. In this regard, a well-written robots.txt file can inform search engine spiders which particular portions of your site should be accessed. Whether running a personal blog or a fully-fledged e-commerce site, an optimised robots.txt file not only increases page ranking but also improves site productivity. Optimally configured robots.txt files help UploadArticles.com.au prioritise content while enhancing audience interaction.
The Concept of Robots.txt
What is the essence of Robots.txt?
A robots.txt file is a document that can be found in the root directory of the website, and it is a simple text document. The document is meant to provide instructions to search engine crawlers regarding which sections or pages they should index and which they should not in order to avoid crawling irrelevant pages.
What Is the Purpose of a Robots.txt file?
A robots.txt file has an immediate effect on a website’s crawl budget. For tall-reaching websites especially, controlling crawler activity within the site is imperative in order to preserve valuable SEO resources and to ensure that every important page is indexed.
How Robots.txt Works
Interaction with Web Crawlers
Prior to a search engine visiting a website, it needs to scan the robots.txt file, if one is provided. This file contains instructions specifying which parts of the website can or cannot be accessed. Compliant crawlers will not scan any disallowed sections or pages.
Impact on Page Indexing
Robots.txt files may stop web crawlers from accessing particular sites, but they do not automatically prevent pages from being indexed. If blocked pages are linked from elsewhere, they may still be included in the index by search engines. Therefore, it is clear that robots.txt is mainly responsible for controlling crawling and not indexing.
Basic Structure of a Robots.txt File
User-Agent Directive
Indicates the web crawler or crawlers to which the instructions apply. For instance, rules may be set for all robots or specific ones like Googlebot.
Disallow Directive
Gives explicit instructions to restrict crawlers from certain parts of a site. For instance:
Disallow: /private/
This prevents all robots from accessing these “private” folders.
Allow Directive
Permits access to specific files within a restricted directory despite the application of the disallow rule. For example:
Allow: /private/public-file.html
This allows the crawlers to scan a disallowed folder.
Sitemap Directive
A sitemap directive is important because it allows a webpage to ensure that all its intended pages are indexed, as search engines will be able to locate the sitemap.

Creating an Optimised Robots.txt File
Step 1: Analyse Website Structure
A web structure should be analysed to discern which sections should be private and which should be public. This is useful in safeguarding sensitive information and optimising SEO.
Step 2: Define Access Permissions
Identify the files or directories that should be included or excluded and why. Ensure that the important SEO documents are able to be accessed while containing the documents that do not need attention.
Step 3: Create the File Using a Text Editor
The robots.txt file can now be created using a simple text program after the structure is defined and all directives are included.
Step 4: Test for Errors
Syntax mistakes are dangerous as they may block important pages from indexing. You need to check the robots.txt file with Google’s Robots.txt Tester to ensure there are no mistakes.
Sample Robots.txt for UploadArticles.com.au
User-agent: *
Disallow: /admin/
Disallow: /login/
Allow: /public/
Sitemap: https://uploadarticles.com.au/sitemap.xml
Avoiding Common Mistakes
Unintentional Content Blocking
One of the bigger mistakes is accidentally blocking pages that are highly important, which could have easily been avoided if appropriate review styles are in place.
Syntax Errors
Directives can become ineffective with incorrect formatting, additional spaces, and typos. Before going live, ensure that you check the file with an online tool.
Ignoring Routine Changes
A website’s modification calls for the editing of the robots.txt document. Test and update the file periodically for the sustained performance of SEO.
Extreme Modifications
Allocating Crawling Activity
Smart management of robots.txt allows the search engine to identify and access prioritised pages while restricting scans on other irrelevant sections.
Stopping Unwanted Bots From Accessing Your Site
Some bots may be detrimental to the website. Use the following command to block them:
User-agent: BadBot
Disallow: /
Wildcard And Character Usage
Advanced operators provide more options. Example:
Disallow: /*.pdf$
This forbids the crawling of all PDF documents.
