His private concept is that it performed a job in high quality updates.

Perhaps extra so as we speak than prior to now, rendering and web page structure play an vital function due to the elevated curiosity in Core Web Vitals.

“Can rendering search engine marketing assist me rank higher?”

Martin paused a second to assume then answered:

“I often don’t reply rating questions. I’ll make an exception right here.

Generally talking, no.

But particularly talking, if there’s a downside the place one thing breaks your render and the content material doesn’t present up, then if the content material doesn’t present up and Google doesn’t see the content material correctly, then, that may truly harm you within the sense of, we don’t see the content material.

So we would not index the web page or we would index the web page, however not rating for the content material that you just care about.

So sure, ultimately it might make a distinction and it might have an effect. Yeah, after all.”

Where Rendering Fits From Crawling to Indexing

Martin Splitt mentioned the difficulty of bandwidth and the way it impacts crawling.

Martin continued:

“We get numerous your URLs and we get so many URLs that we are able to’t crawl all of them on the similar time for the plain causes.

We can’t crawl all of the URLs on a regular basis on the similar time for causes of bandwidth. So there’s solely a lot web bandwidth that you should use.

If you may have a web based store and also you come on-line tomorrow with the brand new on-line store web site and you’ve got 1,000,000 product URLs, your server would possibly crash if we crawl all these million URLs on the similar time.

So we now have to unfold this out by time, so there’s a queue in between us discovering a URL and the URL truly being crawled.”

From Crawling to Rendering

Martin subsequent explains the subsequent steps on the highway to indexing content material.


“What occurs then is as soon as we now have crawled, we are able to already look into the HTML …we are able to see …into the HTTP standing.

If it’s a 404 HTTP standing, then just about the processing ends right here. If there’s a robots meta tag that claims not to index, then our work ends right here as nicely.

But if we get a bunch of HTML content material and we are able to go ahead with processing that in the remainder of the pipeline, we additionally then queue the web page for JavaScript execution, which is what you’ll name it “rendering.”

The second queue could be very opaque within the sense that you just don’t actually see how lengthy it takes us to render.

So like within the consumption, there’s the URL that we uncover and the output of that’s both an listed doc or a non listed doc.

That’s just about what can occur right here.”
