I've noticed something with smaller sites trying to index on big topics - re-requesting indexing reliably drops your position for at least the first 24 hours or so. For a site still building authority, that's rough because click-through is everything for jumping up. If your position drops a page or two, nobody's clicking.
I used to request indexing whenever I had quota spare. Then I tightened up and only did it for significant page changes. Now I'm considering not requesting at all unless the page hasn't been crawled or has rich result issues. End of the day, crawlers pick up changes regardless of whether you ping them again.
A colleague pointed out that the 24-hour dip is probably more about Google reprocessing the doc and query fit rather than CTR. On small sites without much crawl history, it feels dramatic because there's no authority smoothing it out.
Another take I heard: only hit re-request when you add or remove a page. Otherwise, focus on building quality content. If the page has been crawled recently and has no rich result problems, another request is just noise.
Curious what everyone else does - do you still use re-request as a routine refresh, or have you backed off like me?
