For any small organisation with little to no budget, taking an analytical approach will take a long time and require a lot more work then bigger competitors.
If you are a small business in a similar position to Brentford, putting time into researching how websites rank on google, rearching what the top online competitors did to get to where they are, and correctly implementing an SEO strategy will help you eventually compete with bigger companies (The Brentford squad value is £400 million compared to chelsea’s £1 Billion squad).
It took Brentford 13 years to reach the premier league from league 2. While hopefully it will take you less than 13 years to rank for your chosen keywords, SEO can still take up to a year to rank for even niche areas.
The biggest advantage for both SEO and Brentford is that even if they begin to use other strategies that fail, they have already built a solid base that will last for years to come.
