Should your SEO roadmap be a strategic question for your business?
Your SEO roadmap is strategic to keep all SEO-related activities on track, but it is also a key element for your business. It could have an impact on your design and UX, and should be shared with the team involved. For example, you should share your roadmap with the IT team if the implementation of some technical elements require developer cooperation. They will be more likely to collaborate with you if they understand your vision and project as a whole.
Particularly in companies where business occurs online, or your product is an online service, it can be extremely important to evangelize SEO in your company and to recognize SEO as a major marketing axis.
