Our reports sometimes show structured data issues triggered if structured data items contain fields that do not meet Google’s guidelines. Implementing and maintaining your structured data correctly is important if you want to get an edge over your competitors in search results. If your website markup has errors, crawlers will not be able to properly understand it, and you may run the risk of losing the chance of gaining rich snippets and getting more favorable rankings. For more information on the structured data requirements, see schema.org or Google documentation.
