Sites typically won’t get punished for having different content on mobile and desktop
Because Google has switched to mobile-first indexing, this means that Google very rarely crawls the desktop version of a site. Therefore, punishment for differences between the versions is unlikely, as any differences between mobile and desktop probably won’t even be detected. Googlebot does crawl the alternate version of a site from time to time, but this is primarily to confirm the connection between the two, rather than to compare the content.
Google algorithms can still lose trust in sites displaying a strong pattern of manipulative links
Google tries to isolate and ignore spammy or toxic backlinks. However, there still are some cases where a site with a very strong pattern of unnatural links can lose trust and be penalized with a drop in visibility.
Sites with Reconsidered Penalties are Not Monitored More Closely
Google doesn’t monitor sites which have had a penalty and successful reconsideration request more closely afterwards, and there’s nothing that hangs around.
Repeated Reconsideration Review Requests Are Not Delayed
Google will process multiple reconsideration requests without waiting for a fixed period between the reviews, but if they see a website going back and forth they might wait longer to take a look.
Google Wants to Automatically Ignore Unnatural Content
Instead of applying manual penalties for unnatural content, Google wants to develop automatic solutions to ignore anything unnatural, like they already do for unnatural linking, so it won’t harm you and you won’t have to take any action. But in any situation where a penalty would be applied, the reviewer would probably take the time to look at the site.
Reconsideration Requests Can Take a Month to Process
It can take Google up to a month to respond to reconsideration requests, particularly linking related issues. Google doesn’t send warnings first because they want to take immediate action when they find content with a problem.
Abuse of Schema Policy May Result in a Sitewide Manual Action for the Specific Type of Rich Result
Usually if you go against schema policy, a manual action for the specific type of rich result could be applied for the entire site until a reconsideration process is completed.
A Domain’s History Won’t Affect Reconsideration Requests
As long as your site isn’t repeatedly receiving manual actions, the domain history won’t affect the priority or complexity of a reconsideration request.
Google Can Pass Penalties from Migrated Spam Sites
If you redirect a website that has received a manual action for spam to a different website, Google will be able to follow this and is able to penalize the target destination site if you have redirected between the websites yourself.
