What is Edge SEO? SEO at CDN level (Cloudflare/Vercel)

"Waiting for Dev is a nation!" The SEO's world problem that Edge SEO will end.

Have you ever? That you encounter 404 ERROR simple that must be resolved But when sending the story to the Developer team, he received the answer that "Queue for work until next month" or would like to try to change the Title Tag only some pages to do A/B Testing, but the process is complicated and complicated to fold the project ... If you are SEO, whether technical or content lines I believe you have to hurt with "Walls that are invisible" between the SEO team and the Developer team countless times. These problems are not a trivial matter, but it is the "cost of opportunity" that makes us move slower than competitors and missed important opportunities. In the unfortunate rankings

Why is it easy to solve SEO? It became "elephant" for the developer team.

This problem is not caused by the Developer team, I don't want to help. But we have to understand that "home" or the website of the website (Website Architecture), most of them are highly complex. Code correction "The main server" (Origin Server), even a little It may affect the chain to other parts of the system. The Developer team must have a testing process and a strong system that takes a long time to prevent the entire website to fall. Developer's working cycle is often planned in the "SEO urgent". This is the point that causes the "bottleneck" that SEO people have to face regularly.

Prompt for illustrations: The complex schedule show "Origin Server" is like a vault that has been locked tightly, with a Developer team standing to protect while the SEO team tries to send notes that say "Redirect 301", but can't do it. Conveys difficulties in accessing and editing the main code

Let the "slow" to bite. Ranked: The impact is more terrifying than expected.

SEO adjustment is slow, does not mean that we will "To the goal slower" only But it may mean "the backing of the back". Imagine: You found an important product page that became 404, but the Redirect cannot immediately rush to collect the data repeatedly. And found only emptiness What happened is loss. "Budget of data collection" or Crawl Budget The rankings of that page gradually Disappeared from the search results or on the day that Google announced a new algorithm update Your competitors can adjust the web in accordance with a few days. But you have to wait for a month The damage that has occurred is almost impossible to assess the value, both in terms of traffic, leads, and sales that should be yours.

"EDGE SEO" Secret weapon of the modern SEO: Solve the game at "Page". No need to reconcile anyone.

How can we break this wall? The answer that is about to change the world of SEO forever is "Edge SEO". Imagine that Instead of running in to edit the code that "The main server" is very fragile. We moved to work at the "Page" of the website, which is the level of CDN (Content Delivery Network) like Cloudflare or Vercel. Instead of CDN, it is like a server that is distributed around the world. Responsible for sending website information to users and Search Engine as soon as possible. Edge SEO is the use of the "capabilities" of these CDN to "trap" and "change" commands (Request/Response) before it reaches our main server. Simply put, we can edit or adjust the seo at the internet ". Without having to touch the main code, even one line! This is a true game change.

In order to be clearer Take a look at the large E-Commerce website that sells products around the world. They have problems with hreflang tags to tell Google what the product page has for the country and what language. To go to fix the code to put the hreflang correctly, every page is a project that takes more than 6 months and is very risky to the SEO. The SEO team decides to use the EDGE SEO on the Cloudflare Workers. They create a simple script to "trap the" URL ". The correct HRTML of the EDEL's EDE. What is the result? They only take "3 days" to test and release this feature. And within less than a month, Google began to understand the enormous international web structure, resulting in more than 40% of foreign traffic without having to wait for the Developer team.
