1. Naming the images
Every image has default file name that the camera usually allocates (IMG XXX). But always ensure that it has been renamed keeping in mind the key word. It is important that the label contains the keyword since it gets identified by algorithm during the SEO. The search engine will crawl and find the images with this file name and hence image optimization is crucial.
2. Doing justice to ALT tag
While using images in the articles, it is also essential to add the alt attributes and title tags since they enhance the signal for search engine spiders and helps the content to be found easily.
The alt tag helps to label what is on the image. These words are picked up by the search engine and help to identify what is on the image.Alt attribute helps to boost the SEO of the pageand helps to get the website better ranking.
Lot of e-commerce and shopping websites use this mechanism to ensure that the image also shows up when someone searches for a similar item.
3. Using comprehensive visuals
If you are trying to sell a mobile phone inevitably you would like to display multiple images of the same product. This gives the visitor a complete idea of the look and may help with the decision making. Here the images would each contain a different alt tag with indicating if its front view, side view or rear view. Hence all these images would show up on the search page. Different descriptions would be used to ensure that multiple images show up.
4. Loading speed
The loading speed of a site shouldn’t be compromised just because a massive image is used. The size of the image must enable the loading to be quick. It would be a loss if the image is causing a delay which results in people exiting the website
5. Unnecessary images
Images which contribute to overall aesthetic and looks but not really in terms of value shouldn’t be used in HTML. They should be restricted to being present only on the CSS and an empty alt attribute can be used to ensure that this content is skipped by the reader.
Nielsen actually wrote back in 1997: “Elements that enhance scanning include headings, large type, bold text, highlighted text, bulleted lists, graphics, captions, topic sentences, and tables of contents.”
Not all images necessarily need captions. Some images are there for no specific purpose. However it is essential to ensure that we treat this from the perspective of the reader and not merely the SEO aspect. If it is something that may keep the reader engaged and manages to draw their attention then it could be retained.
Other elements such as alignment and image size (not to be mistaken with file size) are also essential to successful use of images. Caution needs to be maintained to sync the choice of images with the overall flow of content. Elements of humor and drama can be used but not at the cost of damaging the overall feel and intentions of the content.
