What are the most common image optimization mistakes to avoid?

Here are some of the most common image optimization mistakes to avoid: 1. Using the Wrong Image Format Choose the right format for the right purpose like JPEG, PNG, WebP & GIF and avoid using SVG for photographs. 2. Ignoring Image Size and Dimensions 3. Forgetting to Optimize Filenames and Alt Text 4. Overlooking Image Compression and Quality 5. Neglecting Responsive Images and Lazy Loading 6. Skipping Image Testing and Analysis 7. Don't forget to optimise images for featured images and social media posts 8. Review and update your image optimization strategies as technology and best practices evolve. 9. Consider using a Content Delivery Network (CDN) to distribute images globally and improve loading times.

Common image optimization mistakes include using the wrong format, neglecting image compression, ignoring responsive design considerations, and not leveraging lazy loading. Optimize images for the web by choosing the right format (JPEG for photos, PNG for transparency), compressing without compromising quality, adapting sizes for various devices, and implementing lazy loading for faster page loads.

Optimizing images for your website is crucial. Choose the right format and compress files to maintain smaller sizes for faster loading. Always add descriptive alt text to help with accessibility and SEO. Ensure images are the right size and responsive to different devices. Consider lazy loading to improve page loading speed, and implement caching for returning visitors. These steps enhance your site's performance and provide a better user experience overall.

Choosing the wrong image format in SEO can impact page speed and search rankings. Opt for efficient formats like JPEG for photographs and PNG for graphics. Oversized images or using inappropriate formats may lead to slower load times, affecting user experience and SEO performance negatively

In my opinion, one of the most common image optimization mistakes to avoid is using the wrong image format. Choosing the appropriate format, such as JPEG for photographs or PNG for transparent images, can significantly impact the image's quality and loading speed on a website or application. Additionally, failing to compress images properly or using excessively large file sizes can also hinder performance and user experience.

A common mistake that people often make is not thinking about how images look on different devices, like mobile phones and tablets. Since a lot of people use their phones and tablets to browse the web, it's important to make sure images look good as well as load fast on these devices too. Using tools and plugins that automatically change the size of images to fit the screen they're being viewed on can really help make you optimize the images for different devices.

I have noticed that the images you upload can significantly affect the loading speed of a website. As a result, I carefully analyze the size and dimensions of the images to effectively address this issue for the clients' business website.

We have learned through our SEO services over the years that size matters, especially with mobile page load times (speed). This is why you must optimize images for mobile first, and desktop second.

Mi opinión al respecto es mi firme: nunca debemos subir imágenes a un contenido de la web/blog con un peso de más de 100kb. Hay maneras de respetar este límite en el peso de la imagen sin que l calidad de la misma se resienta. Convertirla a webp podría ser una de ellas. Y en cuanto a las dimensiones, otra regla innegociable: subirlas con una anchura máxima de 800px, con el alto que corresponda. Es una medida suficiente como para que en desktop se visualice en toda o casi toda la anchura del post o página y en la versión móvil tomará la anchura correspondiente para que quede en anchura completa.

Avoidance: Don't neglect image size and dimensions. Solution: Resize and crop images to fit desired dimensions before uploading. Optimize file size for faster loading, preventing layout distortion and minimizing bandwidth usage. Regularly check and adjust image dimensions as needed.

Filenames and alt text should not just be optimized for SEO, but also to enhance user experience, especially for those using screen readers. Descriptive, keyword-rich filenames and alt texts help in better indexing of images on search engines, but they should also be concise and relevant to the image content. Optimizing them can also help increase the overall accessibility of the website.

Unleash the potential of structured data! Incorporate schema markup to provide search engines with detailed information about the content of your images. This advanced technique enhances your images' visibility and helps you dominate in image search results.

Missing alt text accounts for 61% of all homepage accessibility errors. It is important to write a descriptive alt text, which explains the image aptly and is relevant to the post. Also, use the primary keyword naturally and keep it under 125 characters.

If you truly want effective SEO and to have your images show up on Google, you have to properly name your image files and always include metadata explaining what the image is. Remember that this data is used for browsers that cater to impaired users.

I would like to endorse this statement. Both image filenames and alt text should be descriptive, relevant, and keyword-rich, as they can help your images rank better and improve your accessibility. This is the recommended approach in this context.

Image compression and overloading directly affect the user experience. High-quality images often load more and impose pressure on web hosting which results in down website speed. When you have a low page speed, that increases the bounce rate. Eventually, you lose a big chunk of traffic.

Here are some of the most common image optimization mistakes to avoid: 1) Using images with unnecessarily large file sizes 2) Using the wrong image file format for the intended purpose 3) Uploading images with dimensions larger than necessary 4) Serving the same image file to all devices, regardless of screen size 5) Neglecting to add descriptive alt text to images 6) Using generic or non-descriptive file names for images 7) Not implementing lazy loading for images 8) Using default compression settings when saving images 9) Not leveraging Content Delivery Networks (CDNs) for serving images 10) Neglecting to optimize thumbnail images

En el caso que por ejemplo tomemos una captura de pantalla para un artículo tipo tutorial para el blog, MacBook Pro extraerá una imagen tipo png de algo más de 3000 px de anchura (en caso de capturar la pantalla completa). En este caso la redimensiono a 800 px de ancho y la convierto a webp. En la mayoría de los casos este procedimiento baja el peso considerablemente hasta dejarlo en torno a 100kb o menos y la calidad sigue casi intacta.

Avoidance: Don't overlook image compression and quality. Solution: Find a balance between compression and quality for optimal performance. Use suitable image formats, like progressive JPEGs. Utilize online compressors, plugins, or scripts to maintain quality while reducing file sizes. Regularly assess and adjust compression settings based on site performance.

Speaking about lazy loading, another common mistake is implementing it in all the images, including (and this is the mistake to avoid) hero images, or the biggest image in the viewport (it could be a background image). Those elements should load ASAP, so don't lazy load them.

Want to have your competitors zing by you in the SERPs? Then just upload big images with no optimization for mobile and disable lazy loading. See how Google treats you then.

Me gusta activar la opción de carga diferida, perezosa o ‘lazy load’ con el plugin WP Rocket. De esta forma la imagen no carga hasta que el scroll que hagamos llegue hasta ellas. Además me aseguro de que se visualicen correctamente en dispositivos móviles.

Avoidance: Don't neglect responsive images and lazy loading. Solution: Implement responsive images using HTML attributes, CSS rules, or JavaScript libraries to adapt to various devices. Enable lazy loading to delay image loading until they're in the viewport, reducing bandwidth usage and improving site speed. Stay informed about these features and prioritize their implementation for enhanced user experience, particularly on mobile devices.

Check out all the website components from the perspective of search engines and users. This is all about SEO. So, for this, I usually use Ahrefs and Google PageSpeed Insights.

Adopt a holistic approach! Don't just focus on image-specific metrics; consider how your images affect overall site metrics like bounce rate and user engagement. Understanding this broader impact can provide invaluable insights into optimizing your visual content strategy for maximum effect.

Avoid these less discussed image optimization errors: Not updating images regularly can make content seem outdated. Ignoring browser caching for images leads to unnecessary reloads, slowing down the site. Overlooking CDN usage for global sites can cause longer load times for distant users. Not using vector graphics for simple images results in unnecessary large file sizes. Avoiding modern formats like AVIF or JPEG 2000, which offer superior compression and quality, limits performance. Failing to include descriptive captions misses SEO and accessibility opportunities. Lastly, not optimizing thumbnails can lead to disproportionate resource usage, particularly in e-commerce sites where numerous product images are displayed.

Utilizo GTMetrix para estos procesos. Eso sí, si te registras, podrás elegir desde dónde analiza la web esta herramienta. Estando en Espa?a, la opción de analizar desde Londres es la mejor, ya que te dará una métrica más real. Y sobre las imágenes, también te ofrece datos muy concretos y evidencias de qué está fallando en su carga.

Wrong Image Format: Choose the right format (JPEG, PNG, WebP, or GIF) for your purpose. Ignoring Size & Dimensions: Resize images correctly to avoid speed and layout issues. Filenames & Alt Text: Use descriptive names and alt text for better SEO and accessibility. Compression & Quality: Balance compression to maintain quality and smaller file sizes. Responsive & Lazy Loading: Adapt images to screens and delay loading for faster speed. Testing & Analysis: Regularly check performance using tools for improvements.

Images play a crucial role not only from an SEO perspective but also in enhancing user experience to attract and engage website visitors, ultimately converting them into customers. Therefore, never overlook this element when building your business website. Make sure to use appropriate and optimized images.

Think beyond the technical! Understand the emotional and psychological impact of your images. The right visual can dramatically increase user engagement, shareability, and conversion rates. So, invest time in selecting images that resonate with your audience's desires and emotions for a truly compelling online presence.
