ALT tags are HTML elements used to specify alternative text to display when the element they are applied to (such as images) can’t be rendered. ALT tags can have a strong correlation with Google SEO rankings, so when you have images and other elements on your web pages, be sure to always use a descriptive ALT tag with targeted keywords for that page.
What this means is that if someone visits a website and is logged into their Google account, the site owner cannot see the search keywords they used to get there. This has resulted in a great deal of organic traffic being incorrectly marked as direct. The same thing happened to Apple iOS 6 users carrying out Google searches through the Safari browser, after the operating system’s privacy settings were changed, as Search Engine Land reports.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
