Keyword pruning in the context of SEO refers to the process of removing underperforming or irrelevant keywords from your website or PPC (Pay-Per-Click) campaigns. This can help to improve the efficiency of your SEO or PPC efforts, as it ensures that you’re only targeting keywords that are relevant and have the potential to drive traffic and conversions.  Keyword pruning typically involves analyzing keyword performance, identifying underperforming or irrelevant keywords, and then removing or replacing these keywords.
