Questions and answers related to website creation.

46. What are the advantages and disadvantages of using the Content Delivery Network (CDN) service?

Using a Content Delivery Network (CDN) service is generally a good option for optimising website loading speed.A CDN is a network of servers located in different geographic regions that contain a copy of your website content. When a user accesses your website, they will receive content from the CDN server that is closest to their location. This reduces the distance the content has to travel to reach the user and therefore reduces loading time.Using a Content Delivery Network (CDN) can be useful in the following conditions:
  • The site has users from all over the world: A CDN can reduce page load times for users in other regions or countries by delivering content from servers closer to users.
  • Thesite has high traffic: The more users the site has, the greater the chance that the servers will be overloaded and slow down loading speed. Using a CDN can reduce this problem by distributing the load across multiple servers.
  • The site has many media files (images, video, audio): Large media files can slow down page loads. A CDN can help speed up the upload of these files by storing them on separate, fast servers.
  • The site uses dynamic content: Dynamic content, such as user-generated data, can be delivered faster with a CDN by delivering content from the server closest to the user.
  • The site is vulnerable to DDoS attacks: A CDN can help protect the site against Distributed Denial of Service (DDoS) attacks by distributing traffic across multiple servers and filtering malicious traffic.
Here are some advantages and disadvantages of using a CDN:Advantages:
  • Faster site loading speeds;
  • Global site accessibility;
  • Scalability: A CDN can help scale the site, as it can take load from servers and distribute traffic across multiple servers, which can reduce pressure on individual servers.
  • Reduced hosting costs: Using a CDN can reduce hosting costs because it can reduce pressure on the main servers, which can reduce the costs required to keep the site online.
  • Improved SEO performance: A site with a faster loading speed can perform better in search engine rankings.
Disadvantages:
  • Additional costs: For small sites, there are free variants. For large sites, using a CDN can be expensive, as it requires paying a monthly subscription to use the service.
  • Complexity: Using a CDN can be complicated, as additional servers may need to be installed and configured to distribute site content.
  • Dependence on third parties: Using a CDN can make the site dependent on third parties, which can affect site performance and uptime if the CDN service encounters problems.
  • Inability to directly manage content: Using a CDN can make it difficult to manage site content, as content can be distributed across the CDN, which can make it difficult to track and update.

47. How can I optimize my website to load quickly on mobile devices?

Improving the loading speed of your website on mobile devices is very important, as the majority of users access websites from mobile phones (currently about 75% of users).In general, mobile devices (phones, tablets, etc.) have fewer resources than computers and for this reason websites generally have slower loading speeds on mobile devices.There are several ways you can optimize your website for mobile devices:
  1. Use responsive design – Responsive design is essential to ensure that your website will display correctly on mobile devices. This design allows your site to adapt to different screen sizes, meaning your site will display correctly on a smartphone.
  2. Optimize image size – Large images can slow down page loading, so you need to make sure their size is optimal. You can use an image compressor to reduce file size without losing image quality.
  3. Reduce page size – Smaller pages load faster, so you should reduce the size of your pages as much as possible. To do this, you can remove any unnecessary elements or reduce the size of multimedia files.
  4. Use a caching plugin – Caching plugins can improve the speed of your site by temporarily storing site data so that it can load quickly. They can be especially useful for home pages, as these are the most visited.
  5. Check and optimise your site’s source code – It is important to optimise your site’s source code to reduce the time it takes to load. To do this, you can use special tools that will help you identify problems and fix them.
  6. Use CDN services – see above for details on using CDN;
  7. Test the speed of your site – It is important to regularly test the speed of your site on mobile devices so that you can identify any problems and fix them.
Here are some examples of sites you can use to test your site speed:
  1. Google PageSpeed Insights – https://developers.google.com/speed/pagespeed/insights/
  2. GTmetrix – https://gtmetrix.com/
  3. Pingdom Tools – https://tools.pingdom.com/

48. What if my website is not compatible with all web browsers?

If your website is not compatible with all web browsers, your pages will not display correctly and you will basically lose some visitors and therefore potential customers.Different web browsers display web pages in different ways, and website developers need to take this into account to ensure that the website is displayed correctly on (theoretically) any browser.If your website is not compatible with a popular browser such as Google Chrome, Brave, Edge, Safari or Mozilla Firefox, users accessing it through these browsers may experience display and functionality issues.In addition, poor web browser compatibility can also affect your site’s ranking in search engines, as they take into account web browser compatibility in their ranking algorithm.

49. How can I make sure my website will be compatible with different web browsers?

Each web browser may display your website differently, which can lead to a poor user experience for your users.Here are some tips to help you make sure your website is compatible with different web browsers:
  1. Test your website on multiple web browsers: This is important to see how your website looks and behaves in different browsers. If you can, test your website on the most popular web browsers such as Google Chrome, Brave, Opera, Mozilla Firefox, Safari, Microsoft Edge etc..
  2. Use web standards: Make sure your website follows web standards such as HTML5 and CSS3. These are supported by most browsers and can ensure that your website will display correctly on most devices and platforms.
  3. Avoid outdated technologies: Avoid using outdated technologies, such as Flash, as they may not work correctly or at all on some browsers.
  4. Use responsive design: Make sure your website has a responsive design, which means it will display correctly on mobile devices. This will ensure that users have a good user experience no matter what device they are using.
  5. Test your website on mobile devices: Test your website on multiple mobile devices or use simulators for different devices to make sure it is optimised to display correctly and work well on them.
If you’re worried about browser compatibility, you can call a web design expert or web developer. I recommend Webage.

50. What types of images should I use on my website?

Useful tips you can follow to choose the best types of images for your website.
  1. Use relevant, high-quality images
Choose images that fit the theme of your website and are of the highest quality. Low-quality or irrelevant images can have a negative effect on the user experience and affect the credibility of your website.
  1. Resize images to the right size
Quality images don’t have to mean very high resolution images. Large images can slow down page loading and affect the performance of your site. Resize and optimise all the images you upload to your site.
  1. Use appropriate image formats
Using the right image formats can have a significant impact on the performance of your website. In general, the best image formats for the web are JPEG, PNG, SVG and GIF. JPEG is ideal for photos and complex images, PNG is more suitable for graphics, SVG is good for logos and icons and GIF for animations.
  1. Use alternative text for images
Alternative text (alt text) is descriptive text that appears in place of the image when it cannot be displayed. It’s important to add alt text to every image on your website so that users can understand what the image represents, even if it can’t be displayed.
