We've been working with an SEO agency for two years on our B2B industrial equipment site with a monthly budget of 38,000 TL. Over the past six months, their reporting has been superficial and no new strategy is being produced, so we decided not to renew the contract. We're shaking hands with a new team at the start of next month, but I'm really worried about running into a technical and operational vacuum while parting ways with the current agency.
Right now, organic traffic accounts for about 35 percent of our revenue. Even though ownership of Google Search Console Analytics, and tag management accounts technically sits with our company email historical disavow lists, unpublished content drafts, and the breakdown of backlinks acquired to date are kept on the agency's own dashboards.
What step-by-step checklist should I follow during this transition period to ensure a seamless handover to the new agency without losing rankings or trashing all our past work? What do I absolutely need to request officially from the old agency before clearing the final invoice?
