This is a minimial blocklist based on the W3Tech annual surveys on most used webtechnology. In stead of crawling the web analyzing
|
|
|
|
|
Alexa's TOP 500.000 websites, I looked at the web industry itself, to block the bulk of the mainstream advertising services with the
|
|
|
|
|
obvious benefit of low maintenance effort (for me) and low performance impact (for the adblocker you are using).

WHY USE A MINIMAL BLOCKLIST?
|
2020-02-20 09:10:34 +01:00
|
|
|
In advertising the number one (Google) has a marketshare of around 40 percent, Facebook the number two hits the 20 percent mark
|
2020-02-20 09:34:45 +01:00
|
|
|
while the number three Comscore just has a little over 2.5% marketshare. For comparison Amazon with its huge webstore generates
|
2020-02-20 09:34:18 +01:00
|
|
|
about the same advertising traffic on its own website.

|
Number 200 on this list only has a marginal market share of 0.1 % 1n the Alexa top 10000. Imagine how effective URL number 50.000 will
|
2020-02-20 10:27:04 +01:00
|
|
|
be of your blocklist. Fair chance it will never be triggered. Some adblockers have an option to exclude URL's with low usage (like
|
|
|
|
|
AdGuard 'use optimized filters' option) or periodically filter out dead URL's (Opera's and Brave's build-in adblockers).

Opera performed an analysis on the effectiveness of Easylist and reported in a blog that 20 percent of the listed URL were dead and
|
|
|
|
|
another 60% had a 'hit rate' of less than 1% of all the traffic of the Opera browser users (having agreed to provide telemetry data).

Scientific studies show that large blocklist are a little more effective on 'long tail' websites (not in Alexa top 500.000 with more
|
|
|
|
|
than 2000 unique visitors per day), but a little less effective on Alexa top top 300000 (websites with more than 3000+ visitors per
|
|
|
|
|
day). Websites with many visitors are more likely to install adblock walls to protect advertising income. Anti-adblock walls often

When you want a common use well maintained small blocklist, use Disconnect's Simple Ad-filter or Peter Low's blocklist (both have over
|
2020-02-20 12:48:08 +01:00
|
|
|
3000 blacklisted URL's). Disconnect filter is also used by Firefox and Edge anti-tracking. When you want a well maintained medium sized
|
2020-02-20 12:47:35 +01:00
|
|
|
blocklist, use Steven Black's blocklist (more than 50.000 URL's blacklisted). When you want a large blocklist have a look at the
|
|
|
|
|
'ultimate' blocklist of Energized.pro (over 700K URL's blacklisted). Benefit of Energized is that they rempve dead URL's.

ERRORS & ISSUES

|
|
|
When you still want to use this blocklist, feel free to use it and provide feedback on errors. You can post issues, but I will only have
|
2020-02-20 11:05:14 +01:00
|
|
|
a look at it when the issue causes a problem on an COM, INF, NET or ORG domain. You can fix a problem easily yourself in most adblock
|
|
|
|
|
extensions (e.g. AdBlockPlus, Adguard, uBlockOrigin). Look for UserFilter or MyFilter in the extension options. For instance when this
|
|
|
|
|
filter causes a problem on website ABC_example.com, simply add a badfilter using this syntax:
