As website owners, we keep an eye on the visitor numbers to the site, and usually expect to see this number either grow or stay roughly the same month on month. It can happen sometimes that the traffic drops to the site. What causes this?
Sometimes it is purely a seasonal issue – if you sell items which are mainly based around particular seasons or times of year, you can expect the traffic to drop when you are out of your season.
On the other hand, it could be that your keyword rankings are dropping, making your site less visible to customers on Google etc. In this scenario, it is important that you check over the content of your pages and ensure you have enough relevant and keyword rich content. This is how Google et al make their choices about how to rank your site. If there isn’t enough content, it simply cannot rank you effectively.
