How Image Optimization Brings You More Traffic?
Image optimization can highly impact search engines’ results.
How to Use Keywords, Alt Tags,
& Meta Tags for Images?
As an SEO expert, I’m often asked, “Do we need to put labels on images to get more traffic on the website? Can we just use keywords in alt tags for images?” The answer to this is very simple.
Just think about searching a few images on Google. Maybe I can search for the tastiest-looking recipe, for example, of tortilla soup on Google. When I scan Google images related to tortilla soups, I get to know that everyone has a different recipe. Now, if I desire to find a recipe that makes a thicker soup, it would be a time-taking task to go through each recipe one-by-one until I get the perfect one.
If the images are labeled properly, it can save a lot of time by simply scanning through the labels of the images and identify the desired recipe.
Another example could be of DIY solution to fix a certain part of my car. If I simply go through Google search results, it might be frustrating for not finding the right solution. Instead, I can switch to Google images, have a look at different images and their labels, and find the exact solution that I need in just a couple of minutes. This shows how image optimization can highly impact search engines’ results.
Image Optimization Case Study
If you just fill the alt tag of the images with keywords, people might not be able to locate the images that they really need. To further explain this, let’s continue with our tortilla soup recipe example.
The two alt-tags “world’s best tortilla soup recipe” and ‘thicker tortilla soup recipe’ would have a different impact on the search results. When I searched for ‘thick tortilla soup recipe’, Google showed over thousands of images each of which was linked to a site. However, not all the images were labeled using the ‘filename’ and alt tag relevant to the keywords I used to search for. Still, those images were on the top of the results shown by the search engine.
I selected three images based on the labels and alt tags. The first image that I selected contained filename and alt tag almost similar to the keywords I used to search for. Although it didn’t contain the exact keywords, still it was in the 1st place. The main reason was that it contained a proper title, description of the recipe, h1 tag, and h3 tag.
So, Yahoo Site Explorer showed 46 links out of which 4 inbound links weren’t from the root domain. While Open Site Explorer showed 13 links out of which 1 inbound link wasn’t from the root domain. Moreover, the anchor text distribution for both site explorers used the keywords that this recipe was trying to target.
The 2nd image that I selected consisted of exactly the same filename and alt tag as the keyword. Besides proper title and description, it contained an h2 tag and an h3 tag. So, Yahoo Site Explorer showed 38 links out of which one inbound link was not from the root domain. While Open Site Explorer showed 3 links with no inbound links from the root domain. Also, the anchor text distribution for both explorers used the keywords that this recipe was trying to target. However, it consisted of tons of outbound links that were linked to other recipe recommendations for Chicken Tortilla Soup.
The third image that I selected only contained the title of the image with no description. Moreover, it consisted of only h3 tag such that the heading tags ahead of this tag couldn’t take advantage of keywords. So, Yahoo! Site Explorer showed 23 links out of which three inbound links weren’t from the root domain. While Open Site Explorer showed 23 links out of which four inbound links weren’t from the root domain.
Moreover, the anchor text distribution for this image could be better optimized. Though this image had more inbound links compared to the 2nd image, it couldn’t take advantage of SEO basics i.e., hosting image, using heading tags, a strong title, and a description.
Without a doubt, the 1st image and page were more optimized than the other two images I selected. This concludes that image optimization is far more important than we could have ever thought of.The Google image bot not only looks at the filename and the alt tag, but it also looks at other factors including title tag, meta description, heading tags, links, and anchor text. Moreover, some features like star ratings, filters, etc., can also attract visitors instantly to your website. If you have already been focused on optimizing individual pages of your website, it's time to optimize the images on your website as well.
