3. Migrations are scary
#SEJWebinar

4. #SEJWebinar
The majority of teams we work with have
zero experience with migrations
Roughly half the migrations we see
involve moving to a JS framework
Nearly everyone is worried about
losing rankings and traffic and usually
there isn’t a full plan in place to
mitigate risk
Most migrations are around 4-6
months, leaving teams feeling rushed

6. Technical Issues
#SEJWebinar

7. #SEJWebinar
JavaScript Issues
• Don’t launch without a form of pre-rendering
• The worst damage we’ve seen is when the client relies on Google to render the
content
• Don’t use JavaScript Links
• Google doesn’t crawl them and you’ll mess up your internal linking structure
• Don’t hide your content behind user interaction.
• Google can’t see it, Google can’t rank it

8. #SEJWebinar
Internal Linking
• Don’t drastically change your internal linking if you can help it
• While changes are likely to happen, you need to be aware of your previous internal
linking
• Burying sections of the site behind a few layers of pages never ends well
• Your menu links matter
• Your menu navigation is a strong signal to Google
• We’ve seen countless issues that stem from menu navigation being gutted

9. #SEJWebinar
What went wrong?
• JavaScript Links
• Content hidden behind JS Interaction
• Internal Linking Changes - Menu

10. #SEJWebinar
Launch Day Critical Issues
• Check Noindex tags
• Check redirects
• Check robots.txt
• Check Canonicals
• Rollbacks are not your friend and often bring problems

11. How worried are you about technical issues
during a migration?
#SEJWebinar
• Not worried
• Slightly worried
• Moderately worried
• Very worried

12. Content Issues
#SEJWebinar

13. #SEJWebinar
Changing Content
• Do not change your content when migrating if you can help it
• Changing content removes a formerly stable element
• Google already needs to re-evaluate the site based on changes made
during the migration
• If you must change content, backup old content incase you need to re-add it
• Reverting content can be a key factor in a migration recovery

14. #SEJWebinar
Improper Redirects
• Properly target redirects
• Don’t mass redirect to the homepage
• If a page is missing, find a suitable match (product to product category)
• If an important page has no match, consider recreating the page

15. #SEJWebinar
What went wrong?
• Massive Content Changes
• Content Removal
• Internal Linking Changes
• Phased launch leading to cannibalization

18. #SEJWebinar
Communication
• Don’t bring developers in late
• We find that the later developers are brought in, the more likely technical issues
will persist
• Test early so that developers have time to fix issues
• Be respectful of developer time and properly prioritize issues
• Address issues early
• The sooner you can address problems with things like taxonomy, URL structure
etc., the better
• Don’t expect an issue to be taken care of after mentioning it, follow up on it.

Migration Tips
• The more you change, the harder it is to diagnose what caused a drop
• If you can hold out on certain changes (such as content) and piece it out after the
launch, it’ll be way easier to identify any specific issues
• Don’t be afraid to push back and delay the launch if critical issues are present
• Migrations are bumpy enough without adding additional issues into the mix.
• If a site is going to launch regardless of the issues, make sure to inform the client
or your higher-ups of the potential fallout

21. #SEJWebinar
Migration Tips
• Don’t launch during a Google Update
• Google updates make it hard to diagnose problems
• If one is coming up that they alert you to, pushing back the launch can make it
easier to identify how the migration impacted things
• Avoid Phased Migrations
• While Google now says they can handle phased migrations, we often see problems
with this approach
• Be especially wary of phased launches when dealing with international sites

22. #SEJWebinar
Migration Tips
• Start your redirects early
• Test your redirects if possible (you’d be amazed how rare this is)
• You’ll likely have mistakes that can be fixed with testing
• Be aware of potential better redirect matches down the line
• Triple check your redirects
• Check when the site launches
• Check later that day or the next day
• Check a week later just to be safe

23. #SEJWebinar
Recap!
• Most major issues with migrations aren’t always the most obvious
• Be aware of what’s changing and don’t be afraid to push back.
• Internal linking and content changes aren’t always good
• Keep the migration as simple and “clean” as possible
• Consider saving some changes for after the bulk of the migration
• Good communication and addressing issues early prevent major headaches later on
