How does text for an image help with SEO?

Photos, images, diagrams, info-graphics and other visual aids improve the readability of an article or web page. They also help tremendously to build up the contextual content of the page. They can also help with search engine optimization.

Let’s look into a few to do’s and techniques to help with SEO.

  1. Make sure the image is supporting the content written and place accordingly. It is frustrating to see an image at the bottom of a page when it relates to something in the first few paragraphs
  2. Choose the right file make – SEO for an image starts with its name. There is some debate about order of keywords here but try and follow the subject matter first and the ownership second. For example: Italian Marble Patio custom home designs Kelowna BC
  3. Pay attention to Image size – It is important to understand how a large image can bog down page load speeds. You need to set appropriate files sizes for your images. Do not upload a 1000 x 600 pixel image when you are planning on using it for a 250 x 150 pixel thumbnail image on the site.
  4. Be consistent – do not insert a mass variety of image sizes. Create or follow a style guide for the site and resize your images accordingly. It is a good practice to come up with about 5 sizes and stick to these proportions on web pages and articles in your blog. Do not rely on your CMS to optimize your images. You can use apps for this like Imageoptim, jpegmini or kraken.io. The idea is to achieve a great looking image with the optimum file size.
  5. Add your captions – This may not always be appropriate but captions are read on average 300% more than body content. They also have the same effect as Headings, bold text and bullets in that they slow the reader down and support the browsing of the page. This is an opportunity to engage the reader so try and add captions whenever possible.
  6. The Alternate Text – For the visually impaired the ALT text provides a descriptive about the image on the page. If an image is not available it also ensures the page integrity is preserved.  The information on the page and the functionality on the page still work properly with the Alt text in place. And make sure it includes your keyword.
  7. Title Text – The intent of the title text for an image is to offer advisory information about the image. When you hover over the image the title appears. (In IE the Alt text appears) It can also play a role for social sharing of images as the title help support opengraph. So if a page is shared on Facebook or Pinterest the image is included on the page capture.
  8. And finally ask your developer to set up your XML site map to include your image information. Google want to see images in this XML sitemap as it help them to index images used on your site.

Many websites ignore photo details and this works against them in the long run. If you are serious about improving your site and being competitive online it is an important part of our overall strategy. It may take a little extra time to do but the results will pay off with better rank and position.
