Search Engine Optimisation (SEO) for Images
Optimise the right image to use, either an illustration, chart or photo.
Image SEO will add spice to your blog or website. An image is like an index and tells a thousand words in a single instance. SEO friendly images put live to dull words & illustrate what you mean in an image, or make your social media campaign more attractive.
Finding the right image for your blog post
Your blog needs an image that will do the talking. The image should reflect the content of the blog post.
- The Images must emphasise the title or content of the blog post.
- Innovative images will trigger a visitor to view & read the post.
Choose the right file name for the Image
If your image is about sea beach in Goa then the image name shouldn’t be “IMG_20160410.jpg” instead the image name will be sea-beach-goa.jpg.
Scale up for image SEO
Faster the site, the easier to visit and index a page is. Images can have a huge impact on loading times, especially when you load a large image size and display it really small, like using a 3000×2000 pixels image and showing it at 300×200 pixels size. The entire image will still have to be loaded. Scale the image to the size you want to show it.
Reduce the file size for faster load times
You must reduce the file size for faster load times for a page and make sure that scaled image is served in the smallest file size possible. I strongly recommend you to Install ShortPixels, which will help you to optimise the size of your images and will also help you to load your web page faster.
Images generated by the various software, such as a camera, or a design application, are always needed to be optimised for size. ShortPixels are able to reduce image sizes by as much as 90%.
Compress images help you to load your web page or blog faster as this has a direct relation with search engine ranking in google, bing etc. Images on your blog posts are very useful as they improve the visual experience & make your web content more attractive.
Reduce your blog images for the faster load by using ShortPixels.
I have been using few techniques which can significantly improve the page load time:
Plugins for compressing images without losing quality for faster load times. compressor.io, Kraken.io, tiny png and many other plugins are there for compressing images.
Use high-quality hosting server for your website.
The text that accompanies the image is caption. It’s the text in the gray box below an image. Visitors use that text in scanning a blog’s content. Captions under images are read by more visitors and so you can engage a huge number of potential visitors. You should add a caption if it is relevant to the visitor. Don’t add a caption just for image SEO.
Alt text and title text
Add alt text to an image if an image is not available to the visitors, because they might have turned off images in their web browser or are using a screen reader due to visual impairment. Make sure the alt text includes your SEO keyword and relates to describes the image. When hovering an image, IE shows the alt text as a ‘tooltip’.
Whenever you add an image to your blog’s or websites, you must add Title and Alt tag, which takes care of image SEO. You can add Alt tag manually by adding it to every image you upload. However, when you have an already existing website and you have to edit all previously posted images to add Title and alt tag, then editing manually is a very time-consuming task and a hectic process. To overcome this we have WordPress Plugins like SEO Friendly Images & WordPress Image SEO, which quickly adds Title and ALT tag to your images.
XML image sitemaps
You can use a separate sitemap to list images, or you can add image information to an existing sitemap. Adding images to your XML sitemaps help Google index your images, for better image SEO.
Keep these key points when adding an image to your blog or website:
- Use a relevant image that matches your content
- Pick the right file name for your image
- Image dimension must match with the image size as displayed
- Reduce file size for faster loading
- Add a caption for easier scanning of the page
- Use an image alt text, title text is optional
- Add OpenGraph and Twitter Card tags for the image
- Don’t break the left reading line using an image
- Use images in your XML sitemaps
Vital factors in SEO are using an appropriate image, keywords and tags.
Images on your blogs are very crucial to get traffic from image based search engines like Google image search. Search engine Robots can’t identify your content like a normal visitor. They depend on image ALT tag to identify and understand an image content. Along with this, the texts which are around images also helps to improve the ranking of your blog post images in the search engine.
