Why Local SEO? Companies that improve local SEO in Lancashire or Chorley or other places have a broader influence into individual communities, which, by the way, gives you a larger conversion rate. Local people have friends and family all over the world. When they find a product they like and use every day, the share it with others. They tell two friends and they tell two friends and so on and so on… It’s the old “word of mouth” that broadens your customer base. However, keeping your local customers happy, spreads the word about your company’s product or services.
