Marketing employees can certainly assist you with improving your SEO, but the primary reason for outsourcing your SEO efforts is because it will be simpler. It's also way more affordable for a small business. A seasoned marketer earns an average annual salary between $50,000 and $60,000 plus you'll have to provide them a computer and other equipment; pay for their benefits, vacation, and sick days, and so on. An SEO agency typically runs from $1,800 to $5,000 per month (on average). They don't require training in the field, no vacation, no special equipment, and they guarantee their results.
