There are many different forms of marketing that insurance agents can use here is the pricing for what we found to be the most beneficial.
SEO; you can pay anywhere from $250 per month to $10,000 per month, this all depends on how aggressive you want to market and what sort of results you are looking to see.
Paid Advertising (PPC); paid ads are a lot more expensive than doing SEO or social media marketing. You can expect to pay $200-$2,000 per month for someone to manage your ads on top of your actual ad spend which really has no limit. Again this all depends on how aggressive you want to get.
