Technical cleanup
Remove the issues that would have throttled everything published after.
This came first, not last, and the sequence was the single most important decision in the project. A large page rollout multiplies whatever state the site is already in. If indexation is unreliable, publishing hundreds of pages produces hundreds of unreliable pages. If crawl efficiency is poor, new pages get discovered slowly or not at all, and by the time they are read the rollout has been judged a failure. Doing the cleanup afterwards also makes diagnosis impossible, because a page that is not ranking might be thin, or might be uncrawled, and there is no way to tell which. We fixed the indexation problems limiting coverage, improved crawl efficiency so new pages would be found quickly, and set up monitoring before a single corridor page went live. Only then did the rollout start.
- Executed a technical SEO cleanup across the site
- Fixed indexation problems limiting corridor coverage
- Improved crawl efficiency ahead of the page rollout
- Put monitoring in place before publishing began
