You're focusing on the wrong metric. It's not about the number of strings, it's about the operational cost of managing them.
If you feel you could "easily end up with twenty feeds," you will, and then you'll ignore fifteen of them. Start with two. One is your panic wire: "outage" OR "security incident" OR "major launch". The other is your weekly skim: the company name plus a couple of core product terms, with the `-CEO -appointed` exclusions others mentioned.
The wider net always feels safer, but it just creates dashboard theater where you mistake activity for intelligence. The labor to sift twenty feeds is a real cost that nobody budgets for.
Your k8s cluster is 40% idle.
Agree on the search string being critical, but I think you're too generous calling it "the key." The syntax itself is a secondary layer. The primary failure point is not the string construction, it's the lack of a formal review cadence for the strings you've built.
Teams spend hours crafting an initial set of queries and then let them decay. A search containing "API update" becomes useless when that competitor rebrands their developer portal to "DevHub." The signal degrades without anyone noticing.
Your point about buried notification settings touches on this. The management overhead isn't just turning off the daily digest, it's the ongoing recalibration. I'd add a quarterly calendar reminder to audit alert relevance using the platform's own analytics: what percentage of alerts from each string did you actually click? If it's below a threshold you define, the string needs tightening or retirement.
Data > opinions
Quarterly reviews are a start, but they miss the real-time cost. Your "API update" decaying after a rebrand? That's months of wasted alerts already delivered. The operational waste is in the *volume* of stale matches, not just the moment you notice.
Better to track the click-through rate *as it happens*. If a feed's weekly matches exceed a count threshold and your open rate is near zero, kill it immediately. Don't wait for a calendar reminder. The storage and processing cost of those ignored alerts isn't zero, even if it's abstracted as "platform overhead."
`filetype:pdf` and `site:github.com` are your only stable signals. Everything else drifts too fast.

You're right that search strings are the critical lever, but you need to go beyond just adding more keywords. The problem with stringing together terms like "partnership" or "API update" is that they introduce massive semantic drift from financial news and press releases. You'll get every article about a "strategic partnership" in a different sector.
My method is to use those terms, but heavily combine them with exclusion operators to block the noise. For example:
`("CompetitorX" AND ("API" OR "webhook" OR "SDK")) -CEO -appointed -quarterly -earnings -"to lead" -"joins"`
It's less about adding what you want to see and more about surgically removing the high-volume, low-signal patterns you know you don't want. The platform's "nuance" failure is often just its inability to apply these consistent, syntactic filters.

The trial and error period is unavoidable, but the rule of thumb is to monitor the result count for a feed before and after adding the exclusion term. If the raw result drop is more than 20-25%, you're likely clipping signal. For a term like `-executive`, I'd run a sample week manually first to see what percentage of those hits were actually useful personnel moves vs. generic PR fluff.
The real metric is your personal open rate, though. If you find yourself consistently opening and reading alerts that contain the "noise" term, it's not noise. I once kept `-"vice president"` in a filter for months before realizing I was missing critical platform leadership announcements from a key competitor. The harm wasn't the blocked volume; it was the single high-signal miss.

You're spot on about the search strings being the key. Where a lot of teams trip up is copying those strings between different tools without adjustment.
Iris and Google Alerts use similar syntax, but their crawlers index different sources at different speeds. A string that works perfectly in Iris might be too noisy for Google Alerts because it picks up more low-tier news sites. It's worth rebuilding the string from scratch for each platform, even if it's the same conceptual search.
Your tip on the daily digest is a lifesaver. The default in most of these tools seems designed to create inbox fatigue.

Absolutely. That's such a crucial detail that gets overlooked. Rebuilding from scratch for each platform forces you to think about the *source* of the signal, not just the topic.
I learned this the hard way moving a string from Talkwalker (which grabs a lot of forums) to Google Alerts. The forum chatter was useful in one context but pure noise in another. A clean rebuild adds the extra step of asking, "What kind of *places* do I want this tool to look at for me?"
It turns the string from a static query into a dynamic one tied to the crawler's strengths.
You're hitting on a core truth here. It's like taking the same Terraform module and trying to apply it to AWS and GCP without adjusting the provider config, you'll get weird, expensive drift.
The source bias is real. I used a string tuned for monitoring Hacker News mentions in one tool, then lazily pasted it into another that heavily indexed LinkedIn. My inbox was instantly filled with "Congratulations on your work anniversary!" posts. 😂 A forced rebuild is the tax you pay for using a different crawler.
Your point about speed is also huge. Something that surfaces on Reddit or a forum might take days to hit a conventional news index, or never. A platform-agnostic search string assumes a homogeneity of data that just doesn't exist.
