H2 Tags With Numbered Lists Bypassed Google Meta Description Rewrites
On-page information gain has long provided a way to manipulate the snippet displayed in Google search.
Ted Kubaitis reports using an H2 trick for a numbered list to inject custom copy into the search description and regain control when Google was rewriting a page's meta description.
The behavior indicates that Google looks for, collects, and sometimes displays structured information-gain content in the SERP, though whether the algorithm also scores rankings with that extracted data remains unproven.
