Optimize images for search engines to target your site better. When a search is done for any topic on a search engine , links for images, videos, news, information and blog posts are displayed. Search engines display blended search results. Search engines provide preferential treatment to images that are included in search engine results.
SEO optimized images are more likely to appear in search engine results, optimizing images in coordination with web pages boosts search engine rankings for both. SEO relies heavily on search engine optimized text to raise a page’s profile and facilitate indexing. Since images contain no text describing them, search engines rely on tags, metadata, captions and file names and other contextual clues to identify and properly index images.
When placing images on web pages focus on appearance, placement and SEO.
-Use search engine preferred formats PNG, JPG and GIF.
-Give image files recognizable names such as opel-sail.jpg, do not use cryptic names like opsl2011.jpg. Use dash not underscore to separate words because search engines treat dashes as spaces.
-Always use keyword optimized alt text in the “<img/>” tag.
-If image is used as a link , include keyword optimized title tag.
-Correlate the words in “<img/>” tag’s alt text with surrounding text , the image name and page title.
-Use width and height attributes to specify each image’s dimensions.
-Store files in search engine accessible folder and insert them via image’s URL rather than through a blog or CMS media library database.
