Definition for crawler: A crawler, also known as a web crawler or spider, is an internet program specifically designed to systematically browse the web. The primary purpose of a crawler is to enable search engines to discover, process, and index web pages for displaying in search results.
Traditionally, crawlers are utilized to process HTML content, but there are also specialized crawlers that focus on indexing images and videos.
In the realm of web crawling, it’s crucial to familiarize yourself with the prominent crawlers employed by the world’s leading search engines. These include Googlebot, Bingbot, Yandex Bot, and Baidu Spider.

Good vs. Bad Crawlers: What’s the difference?
A good crawler can be likened to a helpful bot that benefits your website. It contributes by adding your content to a search index or assisting in auditing your website. A hallmark of a good crawler is its ability to identify itself, adhere to your directives, and adjust its crawling rate to prevent overloading your server.
On the other hand, a bad crawler offers no value to website owners and may even possess malicious intentions. It may fail to identify itself, disregard your directives, cause unnecessary server loads, or engage in content and data theft.
Types of Crawlers: Understanding the distinctions
There are two primary types of crawlers:
1️⃣ Constant-crawling bots: These bots perform continuous crawls 24/7, diligently discovering new pages and revisiting older ones. Googlebot is a notable example of a constant-crawling bot.
2️⃣ On-demand bots: These bots crawl a limited number of pages and execute a crawl only upon request.
Now, let’s address the significance of website crawling. In essence, search engine crawlers play a crucial role in understanding the content present on your website and adding it to their search index. If your site isn’t crawled, your content will not be displayed in search results.
Website crawling is not a one-time event; it’s an ongoing practice for active websites. Bots consistently recrawl websites to discover and index new pages while also updating information about existing pages.
By embracing effective website crawling practices, you can ensure that your content receives the visibility it deserves in search engine results, driving organic traffic and fostering online success.
CDN stands for Content Delivery Network. In the context of SEO (Search Engine Optimization), a CDN refers to a network of distributed servers located in various geographic locations. The primary purpose of a CDN is to deliver web content, such as images, CSS files, JavaScript files, and other static assets, to users more efficiently and quickly.
Why is CDN important in SEO?
From an SEO perspective, implementing a CDN can have several benefits. Firstly, it helps improve website performance and speed by reducing latency and minimizing the time it takes for content to reach the user’s browser. Faster load times can positively impact user experience, as visitors are more likely to stay engaged and navigate through a website when it loads quickly.
Additionally, using a CDN can indirectly influence SEO rankings by reducing server load and improving website availability. When a website is hosted on a CDN, the network’s servers handle a significant portion of the content delivery process, offloading the load from the website’s origin server. This can prevent server overload and enhance the overall stability and uptime of the website, which can indirectly contribute to improved search engine rankings.
Moreover, search engines, such as Google, consider website speed as a ranking factor. By delivering content from servers closer to the user’s location, CDNs reduce the distance and network hops required for data transmission, resulting in faster load times. Improved website speed can positively impact search engine rankings, as search engines prioritize delivering a positive user experience.
In summary, a CDN in SEO refers to a network of distributed servers used to deliver web content efficiently. Implementing a CDN can enhance website performance, improve load times, and indirectly contribute to better search engine rankings by optimizing user experience and reducing server load.

Is there any impact on SEO when using a computer delivery network?
The role of CDNs in SEO can be a bit complex, often leading to misconceptions. While it is generally true that CDNs themselves do not directly influence a website’s ranking, they do play a significant role in enhancing overall performance.
CDNs primarily focus on improving the loading speed of a website. By distributing content across multiple servers in various locations, CDNs ensure that users can access the website’s resources more efficiently. This improved loading speed positively impacts the user experience and can contribute to better Core Web Vitals scores, which measure key aspects of website performance.
It’s important to note that search engines, such as Google, prioritize user experience as a ranking factor. When a website loads quickly and provides a seamless browsing experience, visitors are more likely to stay engaged and interact with the site. Consequently, a positive user experience can indirectly benefit SEO efforts by increasing engagement metrics, reducing bounce rates, and potentially leading to higher rankings.
However, it’s crucial to understand that implementing a CDN alone is not a guarantee of improved SEO rankings. CDNs primarily focus on optimizing website performance, while SEO encompasses a broader range of factors, including content quality, relevance, backlinks, and overall website structure. To achieve optimal SEO results, it’s important to combine CDN usage with comprehensive SEO strategies that address all relevant aspects.
In summary, while CDNs themselves may not directly impact SEO rankings, they play a vital role in improving website performance and enhancing the user experience. By delivering content faster and more efficiently, CDNs can contribute to better Core Web Vitals scores and indirectly benefit SEO efforts by promoting positive user engagement.
Co-occurrence in SEO refers to the frequency with which two or more words appear together in a corpus of text, such as web pages or documents, and it plays a role in search engine analysis. Search engines, like Google, utilize co-occurrence analysis to understand the relationships between words and determine their relevance to specific topics or themes.
When analyzing co-occurrence, search engines examine both search queries and the anchor texts of links. By understanding which words tend to appear together in search queries or anchor texts, search engines can infer semantic relationships and associations between those words. For example, if the words “link building” and “keyword research” frequently co-occur in search queries or in the anchor texts of external links pointing to a webpage, search engines can infer that these terms are related and often used together in the context of the topic.
It’s important to note that while co-occurrence analysis helps search engines in understanding semantic relationships, it does not directly influence a website’s organic search ranking positions. Co-occurrence is just one of many factors that search engines consider when determining the relevance and quality of a webpage. However, understanding co-occurrence can still be valuable for SEO practitioners as it can assist in identifying relevant keywords and gaining insights into how search engines interpret content.
In summary, co-occurrence in SEO refers to the frequency of words appearing together in text, aiding search engines in understanding semantic relationships. Although it doesn’t directly impact search ranking positions, it assists in topic grouping and keyword identification, providing valuable insights into search engine behavior and optimization strategies.
Although search engines have the capability to analyze co-occurrence in search queries and links’ anchor texts, it is important to note that the concept of co-occurrence does not directly impact the organic search ranking positions of websites.
Nevertheless, gaining an understanding of co-occurrence can be beneficial in several ways. It aids in the identification of relevant keywords and provides insights into the functioning of search engines. By recognizing which words frequently appear together in search queries or anchor texts, website owners and SEO practitioners can gain a deeper comprehension of how search engines interpret content and make associations between terms. This knowledge can be leveraged to optimize content and improve the overall visibility and relevance of a website.

What is co-citation in SEO for Google and how does it help your SEO strategy?
Co-citation in SEO refers to the mutually beneficial relationship that arises when websites discuss interconnected topics, concepts, and reference each other. It plays a crucial role in influencing search engine rankings by considering the contextual relevance of the surrounding words within links. While link building is a well-known strategy, it is not favoured by Google.
How does co-citation work?
This is where co-citation comes into play (along with co-occurrence, which we’ll explore in the next section). This simply means that a website is mentioned by two different sources, even if they are not directly linked. It’s a straightforward concept. For instance, if multiple websites mention Search Engine Journal without necessarily providing a hyperlink, Google recognizes this as co-citation, which is beneficial for the mentioned website.
The key idea behind this concept is that these mentions can occur naturally or unintentionally, creating a sense of authenticity and credibility. Consequently, the mentioned website and all the other websites referring to it become interconnected, further enhancing their relevance.
A noteworthy insight from a podcast suggests that it may not necessarily be detrimental to have both your site and your competitors’ site linked in the same article. This practice actually helps establish a level playing field through co-citation, as the podcast aptly explains.
Co-citation is a citation metric that measures the frequency with which two documents are referenced together by other documents. A higher number of co-citations indicates a stronger correlation in subject matter between the two documents.
Within the realm of SEO, co-citation is regarded as one of the influential factors that shape Google’s understanding of web pages, their relationships with each other, and their overall relevance.
According to data from Statista, the number of global mobile users is expected to reach almost 4.9 billion in 2021. This is a significant portion of the global population and it’s only expected to grow in the coming years. With such a large number of people accessing the internet from their mobile devices, it’s crucial that your website is optimized for these users.
Google Favors Mobile-Optimized Websites:
In addition to the sheer number of people accessing the internet from mobile devices, Google also favors mobile-optimized websites in its search rankings. In other words, if your website is not optimized for mobile, it’s likely that it will rank lower in search results. This can have a significant impact on your visibility and traffic, as most people don’t go beyond the first page of search results.
Improved User Experience:
Finally, mobile optimization is important because it leads to a better user experience for your visitors. If your website is not optimized for mobile devices, it can be difficult for users to navigate and access important information. This can lead to frustration and ultimately, a high bounce rate (when users leave your website quickly). On the other hand, a mobile-optimized website is easy to use and navigate, leading to a better overall experience for your visitors.
How to Optimize Your e-Commerce Website for Mobile
Use a Responsive Design:
One of the easiest ways to ensure that your website is mobile-optimized is to use a responsive design. A responsive design automatically adjusts to fit the screen size of the device being used, whether it’s a desktop computer, smartphone, or tablet.
This ensures that your website looks and functions well on all devices.
Simplify Navigation
Mobile screens are generally smaller than desktop screens, which means that there is less space to work with. To make it easier for users to navigate your website on a mobile device, it’s important to simplify your navigation.
This may involve condensing your main navigation menu or using drop-down menus to hide some of the less important links.
Use Large, Easy-to-Read Text
Another important factor to consider when optimizing your website for mobile is the size and readability of your text. On a small screen, it can be difficult for users to read small or crowded text. To make your website more user-friendly, use large, easy-to-read text that is properly formatted and spaced out.
Optimize Images and Videos
In addition to text, it’s also important to optimize any images and videos on your website for mobile devices. Large or poorly optimized images can slow down your website’s loading time, which can be frustrating for users.
To optimize your images, make sure they are properly sized and compressed.
Conclusion on the importance of mobile optimisation
In conclusion, mobile optimization is crucial for the success of any e-commerce website. With the increasing number of people accessing the internet from mobile devices, it’s important to ensure that your website is optimized for these users.
Not only does mobile optimization lead to a better user experience, but it can also improve your search rankings and drive more traffic to your website.
By using a responsive design, simplifying navigation, using large, easy-to-read text, and optimizing images and videos, you can ensure that your e-commerce website is optimized for mobile devices.
By taking these steps, you’ll be well on your way to improving your online presence and driving more sales and revenue for your business.
Mobile optimization SEO is essential for any business looking to increase online visibility and drive sales. With more and more people using mobile devices to search the internet, it’s crucial that your website is optimized for mobile visitors.
One way to do this is to ensure that your website has a mobile version that is optimized for small screens and touch navigation. Another important aspect of mobile optimization is page speed. Google’s mobile-friendly test and Google Search Console can be used to test your website’s page speed and identify areas for improvement.
Another important aspect of mobile optimization is mobile first indexing. This means that Google will use the mobile version of your website to index and rank your pages in search engine results pages (SERPs). That’s why responsive web design is important, to ensure that your website will look great and work well on any device.
You should also optimize your titles and meta descriptions for mobile search results. This will help your pages to stand out in SERPs and increase the chances of mobile visitors clicking through to your site.
Overall, mobile optimization SEO is crucial for any business that wants to improve its visibility in search engine results pages, increase conversions, and provide a great user experience for mobile visitors.
What is a desktop and mobile version of a website?
The desktop version and mobile page are two different versions of a website.
A desktop version is designed to be viewed on a larger screen, such as one on a computer or laptop, while a mobile page is optimized for smaller screens like those on smartphones and tablets.
It is important for businesses to have both a desktop version and a mobile page of their website in order to provide a seamless and optimal user experience for all visitors, regardless of the device they are using.
This can be done with responsive web design, which makes it possible for a single website to adjust to different screen sizes and work best on any device.
Having both versions also allows for better SEO, as Google and other search engines have mobile-first indexing, which means that the mobile version of the website is used as the primary version for indexing and ranking on search engine results pages (SERPs).
