So no, there is no penalty related to submitting 300,000 – or any quantity of URLs – unexpectedly. But yes, submitting that many URLs at one time will have unintended results.
Everything I’m writing from this point ahead is my educated opinion, based on things I’ve been informed over many years through people who labored at Google and on my own reviews with larger sites.
Patterns & Anomalies in Google’s Algorithms
Google’s algorithms be aware unusual patterns.
Adding 50 percent extra pages to a website in an afternoon is unusual. But it doesn’t necessarily imply it’s some thing the web page proprietor did.
There are lots of motives this will take place – the maximum not unusual one being that a domain has been hacked.
Google has systems in vicinity to discover this kind of suspicious interest and apply other filters to it, as it’s dangerous to give searchers with a probably hacked website online.
Manual Reviews & Judgment Calls
Sometimes it’ll cause a manual overview, this means that a human will take a look at the scenario and make a judgment name.
I trust that within the system getting to know global, there are possibly fewer human beings reviewing these anomalies than there used to be, however the machines apply the same constructs.
Some of these is probably to flag content that appears to have masses of spammy links in it or seems to be too just like different content.
300,000 SKUs Indexed in 12 Days
In my very own experience, I as soon as had a retail customer with approximately three hundred,000 product SKUs that acquired a competitor and added approximately 300,000 greater product SKUs in a unmarried day.
We notion this is probably a trouble but did it besides.
The internet result is that the brand new three hundred,000 SKUs took about 12 days to be listed. And they didn’t happen a few at a time, the pages had been “held” for those 12 days after which all indexed immediately. I count on that this delay turned into due to a guide evaluation.
The primary web site did now not go through any troubles or losses all through the ones 12 days, and as soon as the brand new products had been indexed, they done in addition to the opposite products at the web site.
This became multiple years in the past, so don’t assume that your pages may be held 12 days now. There’s genuinely no telling for sure.
Why Are You Adding So Many Pages at Once?
The elephant inside the room, even though, is why are you including such a lot of pages immediately?
Presumably, it’d take months or even years to rewrite all of those pages manually. So why would you maintain your potential achievement until they’re all performed instead of rolling them out as they’re finished (one class at a time, possibly)?
If the answer is that really what you’re doing is spinning content or using one of the many commercially available products designed to automate content, tread carefully.
The Future of Automated Content
I’m genuinely seeing a excessive quantity of automated content material in recent times.
Some of them are clever, the usage of database inputs like variety of products or which include a list of the top x products within the category. Some of them even use or three exclusive templates across every class.
Automated content material is performing pretty properly in search right now, but you may be sure it’s got an egg-timer on it.
If these pages don’t simply assist visitors find matters or whole responsibilities, they’re not useful; they’re junk mail. And at the same time as it can no longer appear like it even as you’re ranking nicely and fat and happy, Google’s were given you of their crosshairs.
Penalty, Or Just Bad Choices?
Google doesn’t care what number of pages you’ve got for your internet site if they’re pages that provide price.
But in case you’re looking to get away with something, try not to make it obvious by means of launching all the spam right now.
Google might suppress or clear out those pages now or within the destiny. Or your rankings may additionally get an algorithmic downgrade. But it doesn’t clearly remember what you call it – it’s a penalty.
If you’re making horrific selections approximately the way you’re building your web site, Google gets you in the long run.
