Use Bibblio’s recency setting to show your latest content
If your site has lots of content but only the most recent stuff is likely to be relevant to your audience (such as a news site), you can prioritize recency so that posts published within a chosen time span are more likely to appear as recommendations. (Older articles may still appear, but only if they're extremely relevant.)
Factors such as frequency of publication, total volume of articles and value of your historic content can help you determine which setting will work best for you, or whether you need to influence your recommendations with recency at all.
Recency can be adjusted at any time in your Bibblio account or your WP admin if you are using the WordPress plugin.
Navigate to the Content tab.
Alter the recency boost slider to prioritize new posts.
Wait 24 hours for the changes to apply.
