We have understood what image optimization is for SEO and why it is essential. The next question is how you do it. Image optimization for SEO has various aspects. In the sections below, we discuss how to optimize your imagery for SEO and web.
When you optimize your images for speed, you ensure that your images are not slowing down your site, especially on mobile. Google might penalize you for having a slow-loading website. Google image optimization has its own rules. However, you also want to ensure your images are engaging, well-branded, and optimized.
Some things to remember with image optimization for speed include image file size, image format, and image caching. Here are some standard practices to reduce image sizing and ensure faster loading of web pages for your visitors.
A file’s size determines how fast it loads. A larger asset size will cause a slower load time, frustrating users. Your SEO image size is a significant contributor to page bloat if un-optimized. In particular, with WordPress websites.
Sizing your images correctly leads to better website page loads. Large images can take a long time to load, frustrating your website’s visitors.
You should resize images to the size you need. If you have a high resolution, you are juicing capacity and loading time with the extra data.
Another way to reduce the size of your images is to use the correct image dimensions. If you don’t need the full resolution of an image, then use a smaller size. The image’s standard resolution is 72 pixels per inch (PPI), which is an excellent target.
Finally, avoid using high-resolution images. Many high-resolution images are unnecessary and can slow down your website. If you don’t need the high resolution, use a lower-resolution image.
Simple resizing images is not enough; you must also compress them. There are several different compression tools that you can use, such as jpegoptim, optipng, and Squoosh. These tools will reduce the size of your images without significantly affecting the quality.
Another way to reduce the size of your images is to use lazy loading. With lazy loading, images are not loaded until they are needed. This can reduce your pages' size and improve your website's performance.
You should also use the right file format for your images. You should use JPEG files for photos, and for line art or logos, you should use PNG files. SVG files can also be used for line art and logos, but they are not as widely supported as PNG files. The other common file format used for web images are GIF and WEBp. The table below shows the pros and cons of each file format.
Alt text, or alternative text, is a textual description that appears in place of an image if it fails to load. It helps search engines understand the content of your images, aiding in indexing and improving your website’s visibility. Properly written alt text is crucial for accessibility, especially for visually impaired users using screen readers. Ensure your alt text is concise, descriptive, and includes relevant keywords without overstuffing.
One significant advantage of alt text is its function in assisting visually challenged users who use screen-reading software to interpret information.
Ensuring your alt text is informative and correct contributes to an optimized image for the web and leads to faster web page loading.
Here are some pointers for including alt text in your images:
1. All non-decorative photos should have alt text.
2. Keep it concise and descriptive. Image alt text should be keyword rich to help improve your website’s search engine ranking.
3. In the text, avoid using phrases like "picture of" or "photo of"; explain what the visitor will see instead.
4. Consider if the page would be equally understandable if the visuals were replaced with text equivalents.
5. Ensure the alt text for linked photos conveys the action that will occur when the visitor clicks.
Optimizing images for the web and SEO can help search engines display your images as rich results. Image optimization for SEO can also help your web pages appear with more details on search engine results pages. Structured data is one of the essential elements in improving image search results. When used correctly, Google can add a badge to your images showing that they belong to a particular product or organization.
Structured data adds metadata to your webpage, which allows search engines to understand the content of an image better. To ensure your efforts to optimize images for web & SEO with structured data are successful, Google suggests following their structured data guidelines. It includes specifying an image as a structured data property, providing the image that belongs to the instance of that type, and ensuring the images are crawlable and indexable. If done correctly, you can achieve a more fleshed-out listing in Google Image Search. Please read our guide on structured data and learn how to add structured data for images.
When optimizing them for SEO, giving your images the correct file name is crucial. By doing so, you are helping to provide Google and other search engines with the information they need to rank your images correctly.
When choosing a file name for your image, keep the following in mind:
1. The file name should accurately reflect the contents of the image.
2. The file name should be brief but descriptive.
3. The file name should include keywords relevant to the image.
4. The file name should be different for each image. However if using the same image on multiple pages, keep a cosistent name.
Following these tips will help you optimize your image filenames for SEO.
Social card and Google image SEO are some of the latest techniques in SEO. It simply means that you are optimizing the images you use on your social media sites like Facebook, Twitter, and your website. Maximize the viewing potential you receive by optimizing your images for SEO.
You can do a few things to ensure we optimize you for social media and search engines. The first thing you should do is to make sure the images you upload are the correct size.
For Facebook, Twitter, and other social media sites, you will want to use images that are 1600px by 900px or smaller. You can use a tool like “Image Size” to help determine the correct size for your images. Always use the valid file format. You will want to use JPEG or PNG files for social media sites.
Additionally, you can use the correct keywords in your image file name and the alt text for your image.
Finally, you can also utilize the Open Graph and Twitter Cards. With Open Graph, you can customize the preview title, image, and more for social posts on platforms like Facebook and Pinterest. For Facebook and Pinterest, you need to add the mentioned code in the <head> section.
<meta property="og:image" content="http://site.com/image-link.jpg" />
For Twitter, you can add Twitter cards that summarize your content. For Twitter, you need to add the mentioned code in the <head> section.
<meta name="twitter:card" content="summary"></meta>
These SEO best practices will help you speed up on-page traffic.
A content delivery network (CDN) can help your images and other content to load quickly. They provide servers in different locations worldwide, allowing content to be rapidly distributed and available to a wide area. For example, if you are in the U.S., accessing content stored on a U.S. server is much quicker than pulling content from a server based in Asia.
A Content Delivery Network (CDN) can significantly reduce the loading time of images by caching them on servers distributed globally and delivering them from the nearest server to the user. It not only improves load times but also reduces bandwidth usage. Additionally, CDNs can compress images into lighter formats such as JPEG or WebP, further enhancing performance across various platforms and devices by delivering the most suitable image format.
An image sitemap is critical for domains. It provides for the graphics of the domain proper indexing by search engines. It is beneficial because images indexed by search engines are more likely to appear in search engine results pages (SERPs) when someone searches for images related to the domain.
An image sitemap can also enhance the user experience in a domain, allowing users to navigate quickly to the images they seek.
There are a few ways to create an image sitemap. One effective method is using a tool like XML Sitemaps, which allows users to create XML sitemaps for free.
Alternatively, you can use a plugin for a content management system (CMS) like WordPress. For instance, the Yoast SEO plugin enables users to create and submit image sitemaps to search engines, ensuring proper indexing and enhancing the visibility of your images.
It is essential to include as many images on the domain as possible. Image sitemaps ensure that someone correctly tagged the images with the correct keywords and metadata. Keeping the image sitemap live and up to date is a great practice.
When optimizing images for web, here are some basic best practices:
1. Employ a CDN to offer your photographs quickly to visitors worldwide.
2. Delete any extraneous picture data.
3. Trim the white area and reconstruct it using CSS to provide the padding.
4. Upload the photographs in the appropriate sizes.
5. Instead of inserting text within photos, use web fonts; they appear better when resized and take up less space.
6. Where feasible, use lossless compression.
7. If you require animation, use GIF.
8. If you want excellent detail and resolution, choose PNG.
9. For general photographs and screenshots, use JPG.
10. In some circumstances, lazy-loading pictures may be desirable for speedier first-page rendering.
