While there is no way to say that fresh content will ensure you website content latches on to the top search results for queries, Google emphasizes on content relevancy. Think about it, what's news today is archived tomorrow and ensuring that your website content stays relevant is a must for Google to deem it relevant and be the right answer to a query on search. Products and services are forever evolving, and so is your brand, and ensuring that your content keeps up should be the priority. In addition, it gives your website the scope of adding fresh links and answering the most recent queries or concerns of your customers. Of course, FAQs are an excellent medium to have fresh content on your website. FAQs are forever evolving based on the progress of your business - with the products and services on offer, and it's any easy way to answer the concerns of your customers - which adds up to content relevancy.
