The goal of good SEO (Search Engine Optimization) is to have your website be the one that people go to when they type a few search words on sites like Google to find the information they need. Very few people scroll to the second page of search results, so having your website show up on the first page of search results is your aim.
I've been doing research recently into a variety of SEO techniques to help my websites (and those of my clients) appear earlier in Google search results. One thing I learned was that images play a role in improving your website's search rankings. It isn't an image by itself, but the words associated with an image, that can make a difference. There are three places where words are connected with an image:
The file name
Alt text (alternate text) that appears when the image can't be viewed
An optional caption that describes what the image is about
Using appropriate words that people might search for in these three places will give your website a boost in search results.
SEO image enhancements in Weebly
You choose the file name when you save the image on your computer. This must be done before you bring the image into Weebly.
After you place the image on your web page, edit the image properties. In the Advanced settings, add Alt Text. Also add a caption if you want one.
SEO image enhancements in Squarespace
You choose the file name when you save the image on your computer. This must be done before you bring the image into Squarespace.
In Squarespace, with an inline image, the caption is also the Alt Text. After you place the image on your web page, edit the image properties on the Design tab to add a caption and Alt text. If you don't want a caption, but want hidden Alt Text, use this trick: Select "Caption below," type your caption, then return to the image properties and select "Do Not Display Caption."
It takes a little longer to employ these SEO techniques for images on a website, but I'm hopeful that I will begin to see some improved results over time. Eventually, as with any new habit, these best practices should become second nature.
