At Magnet.me we track the items people are viewing in order to optimize our recommendations. As such we fire POST requests back to our backends every few seconds when enough user initiated actions have happened (think about scrolling for example). In order to eliminate bots from distorting statistics we ignore their values serverside.
Based on some internal logging, we see that Googlebot is also performing these POST requests in its javascript crawling. In a 7 day period, that amounts to around 800k POST requests. As we are ignoring that data anyhow, and it is quite a number, we considered reducing this for bots.
Though, we had several questions about this:
1. Do these requests count towards crawl budgets?
2. If they do, and we'd want to prevent this from happening: what would be the preferred option? Either preventing the request in the frontend code, or blocking the request using a robots.txt line?
The latter question is given by the fact that a in-app block for the request could lead to different behaviour for users and bots, and may be Google could penalize that as cloaking. The latter is slightly less convenient from a development perspective, as all logic is spread throughout the application.
I'm aware one should not cloak, or makes pages appear differently to search engine crawlers. However these requests do not change anything in the pages behaviour, and purely send some anonymous data so we can improve future recommendations.
