I see a lot of posts that look like this:
“I installed an ad blocker, turned off personalized ads, cleared cookies…
Why am I still seeing ads / being ‘tracked’ / feeling watched?!”
So, let’s do a very low–drama, very human Ad Blocking 101.
What it actually does for you, what it doesn’t, and what you can do today without turning your life into a full-time OPSEC job.
Context: I work on a privacy-focused Android browser, but this post is product-agnostic. Use whatever tools you like.
1. What “ad blocking” actually is (in plain language)
When you open a web page, your browser is basically doing this:
“Hey Internet, give me:
– the article text
– some images
– maybe a video
– oh and… 20 different scripts from companies you’ve never heard of.”
Some of those extra requests are:
- Ad scripts (banners, popups, video ads)
- Tracking / analytics scripts (what you click, how long you stay, who referred you)
An ad blocker is basically a very picky bouncer at the door.
It holds filter lists that say:
- “If the request goes to this ad domain → block it.”
- “If this looks like a tracking script → block it.”
- “If this element matches this pattern → hide it.”
Depending on the tool, it may block:
- inside the browser
- at DNS/VPN level
- or a mix
No magic — just rules.
2. What ad blocking is good at
2.1 Cutting down in-your-face annoyances
Pop-ups, autoplaying video ads, fake “You won an iPhone!” messages, sticky banners.
The bouncer says “nope”, pages become calmer.
2.2 Saving bandwidth, battery, and sanity
Every ad = extra images, JS, CPU/GPU usage.
Fewer ads → fewer requests → less junk → less heat + fewer wasted resources.
2.3 Reducing some tracking
Blocking ad domains cuts off a chunk of basic behavioral tracking.
Not perfect, but meaningful.
Think of it this way:
You’re not invisible, but you’re less transparent.
3. What ad blocking does NOT do
3.1 It does not guarantee “no ads ever again”
Websites now embed:
- sponsored paragraphs
- native ads
- recommended content blocks
They look like normal content, so blockers can’t filter them.
3.2 It does not make you anonymous
Ad blocking ≠ anonymity.
It does not hide:
- your IP
- the fact you're logged into big platforms
- device/browser fingerprinting
- ISP visibility
Real anonymity needs tools like VPN, Tor, and better habits.
3.3 It may break some sites
Sometimes blocking scripts breaks:
- login
- comments
- video players
- checkout flows
More aggressive blocking = more breakage risk.
4. Common Myths (Reality Check)
Myth #1: “One blocker = no ads ever.”
Reality: Fewer ads, not zero. Myth #2: “If I block ads, nobody can track me.”
Reality: Plenty still can.
Myth #3: “Sites that still show ads are evil.”
Reality: Many are simply trying to survive.
Myth #4: “If a site breaks, it's the site’s fault.”
Reality: Often it’s a filter list being too aggressive.
5. Practical advice (for normal humans)
Step 1: Turn on basic blocking
Use built‑in browser blocking or an extension.
Step 2: Use one trusted browser for most browsing
Avoid random in‑app browsers.
Step 3: Accept that some sites need lighter rules
Whitelist or reduce blocking only when necessary.
Step 4: Combine blocking with basic privacy habits
- log out of services you don’t need
- restrict app permissions
- avoid blindly accepting all cookies
Blocking works best as part of a bundle of habits.
6. TL;DR
Ad blocking = a smart filter for some junk.
It makes the web calmer, lighter, and somewhat more private.
It does not:
- make you anonymous
- guarantee ad‑free browsing
- stop native/sponsored content
Combine blocking with good habits → best results.
Use ad blocking as a tool, not a religion.
If the web feels less annoying after you set it up,
you’re already ahead of most people.
