The New Moz SEO Q&A: 100K URL Migration Case Study


The author’s sights are entirely his or her own (excluding the unlikely occasion of hypnosis) and may perhaps not normally reflect the views of Moz.

Should you always count on a traffic fall in the course of a web page/URL migration, even a non permanent one?

In case you didn’t discover, Moz not long ago launched a shiny new Search engine optimization Q&A platform for all the earth to see, examine, and use to discover about Seo.

Initially launched as a non-public characteristic for Professional users lots of decades back, the Q&A was opened for public — and look for engine — viewing again in 2011.

In the many years due to the fact, it grew to over 60,000 posts covering each and every Web optimization topic conceivable, and tens of millions of web page sights. For a extensive time, a important part of Moz’s organic website traffic arrived from the Q&A.

Regrettably, though, as frequently occurs, in excess of time the Q&A saw critical neglect. As a final result:

  • The platform gathered a ton of specialized financial debt, building it nearly impossible to update

  • Internet pages loaded so slowly numerous users gave up totally

  • Spam became extra and a lot more common

  • Moderation instruments were being out-of-date, and couldn’t maintain up

For these reasons, two predictable points took place:

  1. The Q&A grew to become considerably less helpful and gratifying to end users

  2. In excess of time, visitors dropped considerably

So Moz had a option: increase the Q&A immediately, or get rid of it.

Thankfully, we pick to enhance it.

Working with the wonderful crew at NodeBB (really recommended, by the way), we rapidly spun up a new Q&A utilizing our present databases, but with fully modern engineering on the front and backend.

Why this migration was tough

We have been below powerful time constraints. What could generally take months, we required to accomplish in a pair of months. This presented special difficulties from an Search engine optimisation viewpoint.

The most significant obstacle? Our complete URL composition required to change. (If we experienced a lot more time, we could have avoided this, but it was a luxury we didn’t have.)

That meant we essential to migrate 1000’s of URLs that looked like this:

The migration also involved all of Moz’s person profiles, which range in the hundreds of thousands. To be honest, most of the consumer profiles aren’t really indexed.

Regardless, this was a big migration!

The other possible red flag was that most of the Q&A would use shopper-aspect rendering — not thought of a ideal Web optimization observe! We could’ve executed a remedy for server-aspect rendering, but yet again, we simply did not have time. We have been anxious Google would have hassle rendering the information, and this could possibly tank our rankings (additional on this afterwards.)

How we executed the migration

To pull off this large migration when reducing the danger of website traffic loss, we followed basic Website positioning website migration very best techniques, alongside with a couple of “distinctive” extras for an additional strengthen.

1. 301 redirect mapping

To set it simply just, how you apply your 301 redirects is possibly likely to make or break your migration implementation.

For us, this was basically the least complicated, most simple section of the job, as we have a great deal of knowledge with web page migrations! (Does anyone try to remember seomoz.org?)

  1. We produced a record of every single feasible URL and URL path. It is astounding how quite a few URLs and styles you could possibly pass up. A good crawler is important to help with this to make guaranteed you never ignore everything. For Moz, we were being equipped to accomplish this with data from Google Analytics, Research Console, and our individual Moz Pro internet site crawl.

  2. We mapped just about every URL to its corresponding URL on the new NodeBB system. While we identified quite a few edge situations, this was comparatively simple.

  3. We created confident to redirect everything by using 301. This is vital for the reason that numerous platforms and developers may well use 302s by default. While Google has told us that they go PageRank similarly as a result of 302s and 301s, Google has also indicated that 301s are a much better canonicalization sign.

Talking of canonicalization, we also ran crawls of the new URL buildings using the NodeBB platform. In situations where by we identified URL paths that did not match our outdated patterns or we imagined ended up extraneous, the NodeBB workforce was ready to effortlessly established up canonicalization patterns to prevent Google in excess of-indexing our URLs.

2. Most sitemap management

A key element of our migration method was sitemap management. This involved two methods:

1. Previous URLs: We previously experienced sitemaps of all the outdated URLs in put. Importantly, we stored these sitemaps are living and registered in Research Console. This way, Google would proceed to crawl the aged URLs and “see” the redirects.

Typically, webmasters make the blunder of getting rid of sitemaps as well early, which may possibly trigger a reduce in crawl amount by Google. This usually means it could potentially acquire more time for Google to system the redirects.

Sitemaps aren’t a excellent promise that Google will go to all your previous URLs, but they do deliver a hint. In truth, we continue to had several thousand URLs right after various months that Google nevertheless hadn’t frequented, even with the sitemaps in place. Regardless, with no the sitemaps of the old URLs, the difficulty could have taken substantially longer.

2. New URLs: Our previous sitemaps had been grouped into lists of 50,000 each — the maximum authorized by Google. You will find some recommendation in the Seo community that grouping URLs into lesser sitemaps can really improve crawling effectiveness.

Luckily, NodeBB allowed us to make scaled-down sitemaps by default, so that’s accurately what we did. In its place of 2-3 sitemaps with tens of hundreds of URLs, we now experienced 130 specific XML sitemaps, ordinarily with no extra than 500 URLs each and every.

3. Spam + cruft cleanup

As I stated previously, the aged Q&A experienced around 60,000 person posts created up in excess of 10 several years.

Inevitably, a quantity of these posts ended up pretty minimal high-quality. We suspected both of those the very low high quality of the posts, along with weak person encounter, could be resulting in Google to rank us reduced.

Yet again, time constraints meant we could not do a entire articles pruning audit. The good news is, NodeBB came to the rescue all over again (this is commencing to seem like an advertorial — I swear it really is not!) and ran all 60,000 posts as a result of their spam plugin to remove the most clear, reduced-top quality offenders.

In whole, we taken out above 10,000 posts.

We did not redirect these URLs, and merely permit them 404 just after the migration. No a person appeared to miss out on them.

FYI: a different fantastic useful resource on articles pruning is this outstanding webinar with Bernard Huang, Suganthan Mohanadasan, and Andy Chadwick.

4. Greater inside linking & person knowledge

Even nevertheless we ended up porting above the exact content material and fundamental style, the migration presented a great option to improve user expertise. To carry out this, we manufactured two small tweaks to the in general UX:

  1. Added breadcrumbs through the app

  2. Additional extremely applicable “connected concerns” in the sidebar

The old Q&A had neither of these options. Users who landed on a issue had no choices to explore other thoughts. As a end result, we endured for years with a frustratingly significant bounce rate and weak internet site engagement metrics.

Final results: Prior to and following the migration

To be genuine, I have in no way witnessed a migration quite like this. Possessing executed a lot of migrations, I did my greatest to prepare everybody for the most possible situation: be well prepared for a 15-30% dip in targeted traffic for 1-3 months whilst Google processes all the URLs.

In reality, nothing even shut to that transpired.

As you can see in the chart under, we truly saw an improve in visitors, just about beginning at day 1.

In fact, in the two months right after the migration, organic and natural Google targeted visitors to Q&A pages was up virtually 19% when compared with site visitors to all other web pages.

What induced this instant elevate in targeted traffic? Was it the improved sitemap protection, the improved interior linking, or one thing else?

We simply you should not know for positive, but we do have a trace.

As soon as we released the new Q&A, engagement figures shot through the roof:

  • Increased time on website

  • Reduce bounce rate

  • Much more internet pages for each session

In small, end users seemed to be substantially happier and more engaged with the new encounter.

Could the enhanced user engagement have helped rankings?

Yet again, we don’t know. Google is alternatively restricted-lipped about how it may possibly or may not use user simply click indicators for position applications, but we do have our suspicions.

Transferring to the long term

We are even now continuing to strengthen the Q&A experience. Most notably, we’re doing work to prioritize pace advancements, primarily in light-weight of Google’s perform about Main Website Vitals.

Regardless, this was unquestionably a delightful migration the place we did not practical experience a visitors fall — not even for a one day!

Most likely if you vastly increase your user working experience, web-site architecture, and Website positioning best techniques, migrations may well essentially direct to a speedy web gain.
