5 More Google Algorithms You Should Actually Know About
Here’s a question I get asked a lot: “Why did my rankings drop overnight, and what did I even do wrong?” Most of the time, the honest answer is — you didn’t do anything wrong. Google just quietly rolled out an update, and your site happened to be on the wrong side of it.
Google doesn’t rank pages by gut feeling. There’s a whole stack of algorithms working behind the scenes, constantly re-evaluating which pages actually deserve to be shown first. And because Google keeps tweaking these systems, what worked for your site last year might not hold up today.
I’ve already written about Medic, Fred, Pigeon, Possum, and MUM before. This time, let’s go through five more that don’t get talked about as much, but have shaped SEO in their own way: Freshness, Payday Loan, Pigeon (worth a second look, honestly), EMD, and Top Heavy. None of these are new — some go back over a decade — but the logic behind them still applies today.
1. Freshness Update
Back in 2011, Google realized something obvious in hindsight: not all search queries want the same kind of answer. If someone searches “how to tie a tie,” a ten-year-old article works just fine. But if someone searches “iPhone release date” or “election results,” they don’t want a page from 2019 — they want something current.
That’s basically what the Freshness Update does. It figures out which queries are time-sensitive and starts favoring newer content for those searches, even over pages that used to rank at the top.
So why does this matter for you? Because if your niche involves anything that changes — trends, prices, news, product launches — sitting on old content is basically leaving rankings on the table.
A few things that actually help here:
- Go back and update old posts with current numbers, examples, and context, rather than publishing only new ones.
- If a topic is trending, get something out while it’s still relevant.
- Show a “last updated” date. It signals to both Google and readers that the page isn’t abandoned.
- Don’t let evergreen content sit untouched for years just because it “still ranks fine” — it won’t forever.
Honestly, this one’s less about chasing the algorithm and more about not being lazy with your old content.
2. Payday Loan Update
This is one of those updates that sounds oddly specific, and it kind of was. In 2013, Google went after some of the spammiest corners of the internet — payday loans, pharma, adult content — where sites were doing whatever it took to rank: stuffing keywords everywhere, buying backlinks in bulk, building fake doorway pages just to funnel traffic.
Google got tired of it and cracked down hard on these industries specifically.
The bigger lesson here isn’t really about loans or pharma, though. It’s that in any niche where money is involved and competition gets desperate, Google pays closer attention. If your industry is one where spam tactics are common, expect more scrutiny, not less.
What actually holds up over time:
- Skip the keyword stuffing — it reads badly to humans and gets flagged by machines.
- Earn backlinks through real outreach, not link farms or paid schemes.
- Especially in finance or health content, double-check your facts. This stuff affects people’s decisions.
- Follow the actual advertising and industry regulations for your space.
If your SEO strategy depends on tricks instead of substance, this is the kind of update that eventually catches up with you.
3. Pigeon
Pigeon came out in 2014 and completely reshaped how local search works. Before this, “coffee shop near me” type searches were oddly inconsistent. Pigeon tied local search much more closely to your actual location and to Google Maps, so the results you’d get finally started matching what was physically nearby.
If you run a business that depends on local customers — a clinic, a café, a service provider — this update basically decides whether you show up at all.
What changed for the better:
- Local results actually reflect where the searcher is standing.
- Smaller, legitimate local businesses get a fair shot at visibility.
- Search and Maps work together instead of feeling disconnected.
- Location-based searches return results that make sense.
If you want to actually benefit from this:
- Keep your Google Business Profile filled out and accurate.
- Your name, address, and phone number should match everywhere — website, directories, socials, all of it.
- Ask happy customers for reviews. It matters more than people think.
- Use location terms naturally in your content, not stuffed in awkwardly.
- Write content that’s actually about your area, not just generic industry posts.
If your business lives or dies by local traffic, this is one update you genuinely can’t ignore.
4. EMD Update
Quick story from the old SEO days: there was a time when you could register a domain that matched a popular search term word-for-word, throw up some mediocre content, and rank surprisingly well — just because the domain name matched what people were searching for. Content quality barely mattered.
In 2012, Google shut that down with the Exact Match Domain update. Owning a keyword-stuffed domain stopped being a shortcut to rankings.
Why this still matters: your domain name is branding, not a ranking hack. If you’re picking a domain purely because it matches a search term, and you’re skimping on the actual content behind it, you’re building on a foundation Google specifically designed to ignore.
What actually works instead:
- Pick a domain that represents your brand, not your keyword strategy.
- Put the real effort into content quality and on-page SEO.
- Build authority the slow way — consistency, expertise, backlinks earned over time.
- Think of your domain name as a first impression, not a growth strategy.
A clever domain might get someone to click once. It won’t keep them coming back, and it definitely won’t rank you long-term anymore.
5. Top Heavy Update
Ever landed on a page and had to scroll through three ads just to find the actual content you searched for? That’s exactly what Google targeted with the Top Heavy update in 2012, later folded into what became the Page Layout algorithm.
Sites were stacking ads above the fold to maximize ad revenue, and users were paying the price in frustration — especially on mobile, where screen space is already tight. Google decided that wasn’t an acceptable trade-off anymore and started penalizing pages built that way.
If you’re monetizing your site with ads, this is worth paying attention to:
- Keep the space above the fold mostly clear for actual content.
- Be especially careful on mobile — what looks fine on desktop can be a wall of ads on a phone screen.
- Avoid pop-ups and interstitials that block the page the moment someone lands on it.
- There’s nothing wrong with ads — just don’t let them come before the reason people showed up in the first place.
A good sign your site’s on the right track: fast load times, clean navigation, content that’s easy to find, and nothing fighting for attention before the reader gets what they came for.
Final Thoughts
None of these five updates work in isolation, and honestly, neither do the ones I covered before — Medic, Fred, Possum, MUM. They’re all circling the same idea from different angles: give people what they actually came for, without wasting their time or their trust.
You don’t need to memorize every algorithm update Google has ever shipped. What you do need is a website that holds up on its own — accurate information, decent user experience, content that’s actually current, and a layout that doesn’t get in its own way.
Do that consistently, and you’re not chasing algorithms anymore. You’re just building something that was going to work regardless of what Google changes next.
