Search Engine algorithms change quite frequently. A good example of this is the frequent changes in search algorithm Google makes every year (in the thousands). Most of these updates are so slight that they go completely unnoticed. However, on occasion, the search engine rolls out major algorithmic updates that significantly impact the SERPs. We recommend an SEO audit every 6-12 months (we can have this rolling every 3 months for you, contact us to discuss an SEO audit package).
