Lasso needs to know where all your links and unmonetized keywords are on your site. In order to do that, when you install Lasso it adds a benign data-lasso-id attribute to your links and keywords.
When you want to update your links, this id allows Lasso to find and update them quickly.
Does This Attribute Affect SEO or Page Speed?
You may see more than just this attribute on your links. Even WordPress themselves sometimes add data attributes to your links to keep track of things.
Don't worry. Adding attributes to your links doesn't slow down your site or affect SEO in any way.
In fact, having these attributes allows Lasso to be lightning-fast when finding and updating your links without going into every post and page.
