SEO is the process of increasing both the quantity and quality of visitors to a site or the web page via search engines. SEO is a method of attracting unpaid traffic instead of direct traffic and paid visitors.

So when we're talking about speed, the SEO agency has the advantage. Whilst in-house staff members are developing their knowledge, the SEO agency can simply get to work right away. Thus, it is more likely you will see results quickly from using an agency.
The experienced SEO agency has the upper hand here. They are far more likely to know the pitfalls of optimization, and how to avoid them. Think about it, if this wasn't the case, they would be out of business fairly quickly!
Lastly, we need to consider the ROI that the campaign should produce. Getting your SEO done by existing staff is going to require an investment of time.
That time might be better spent on the company's existing, regular work. But let's say a contractor is brought in for this purpose. He or she will cost more in salary than the amount required to outsource the campaign to a reputable agency.
These factors lead me to the conclusion that the most efficient process for a company to get SEO done is through an agency. This is the most cost-effective solution and entails the least risk to a website in terms of possible penalties from the search engines.
