Carrying out a website migration while preserving search rankings requires careful planning, attention to detail, and thorough testing. The goal is to ensure that bots continue to discover, analyze, and value your material in the same way they did before the move.

Start by creating a complete inventory of all existing pages including their addresses, page titles, meta tags, and inbound links. This will serve as your foundational guide for redirection accuracy.

Then, implement permanent 301 redirects for each legacy page to its new location. Never map several distinct pages to one new URL unless they are directly interchangeable in meaning and value. Keep redirect loops and cascades to zero to maintain SEO value and bot accessibility.

Update your robots.txt and 横浜市のSEO対策会社 sitemap files to align with the migrated hierarchy and register the changes in your preferred search engine dashboard.

Ensure your migrated site performs at least as well as the old one. Adaptive design and visitor satisfaction must be retained and improved.

Validate redirection paths via tools such as DeepCrawl or Search Console. This helps you detect 404s and improper forwarding.

Track errors in Google Search Console’s diagnostics. Do not alter templates, themes, or platforms mid-migration. This raises the likelihood of ranking instability.

Observe organic metrics for 6–8 weeks following cutover. If you see drops, launch diagnostics without delay. Often the cause is an overlooked URL mapping or duplicate content tag.

Communicate with key backlink partners to update any links pointing to your old domain.

Keep in mind: Full index recovery is a gradual process. So give the process room to breathe. Methodical pacing and accuracy are non-negotiable in safeguarding your organic growth.
