Image Optimization: An easy SEO trick
- SEO |
How to get it right? Here are 4 simple tips that you can implement easily:
- Alt tag: The code of your site must contain an alt tag for every image. The alt tag will speak to Google in its language and it will add up to the keyword density of your page. Suppose you are optimising your page for Italian food, a pasta picture can be tagged as Italian Pasta like this:
<img src="italian_pasta.jpg" alt="Italian Pasta" />
- Image Size: Heavy images can pull down your site's performance. If the loading time is high, your bounce rates will be high and that will affect your SEO results. Sites with high bounce rates indicate poor or irrelevant content quality and search engines drop their rankings. Therefore optimize the images sizes. A file's extension determines its size. Therefore choose wisely a .png, .jpeg or .gif. And use photo editors to get the image size right. Don't use html coding to resize an image.
- File Name: Don't use gibberish to name your image files. An alphanumeric code like DSN0019827.jpg can confuse the search engines. Use readable English language everywhere because that is what search engines understand. So, Italian_pasta.jpg is a lot better than DSN0019827.jpg. It gives you yet another opportunity to include your keyword without stuffing it in the textual content.
- Image Captions: There is no proof that image captions help SEO but there is an indirect relation. And that too a solid one. Imagine a scenario on Google Images. If your image does not have a title, a user will click through it and close it for lack of information. Your bounce rate will increase. Search engines rank down sites with high bounce rates. So, add meaningful captions to your images. If you are showing a yummy dish in a picture, qualify it by calling it 'Delicious red sauce penne pasta made in Italian style'.
This is one of the easiest tricks of SEO. Inserting keywords via images is much better than overdoing it in the textual content. And it needs no professional. If you have some basic HTML coding experience, you can do the alt tags on your own.
