User Reviews

Users generally praise Block or Highlight Search Engine Results for effectively removing unwanted sites from search results by domain, and for offering both hiding and highlighting options. It works with major engines (Google and DuckDuckGo) and can handle large blocking lists, which many find life-changing for research. However, the experience is not flawless: blocking is not universal across engines; some searches (notably Startpage) don’t get blocked reliably. There are limits on how many pages can be blocked and potential performance issues as the block list grows, plus occasional partial hiding. Android support and ongoing maintenance have been noted as concerns.

Pros

Effectively blocks/hides results by domain across Google and DuckDuckGo, cleaning up search results.
Offers both blocking and highlighting options for domains, giving flexible filtering.
Capable of handling large blocking lists (thousands of sites).
Significantly improves research workflow and reduces clutter, often described as life-changing.

Cons

Engine compatibility issues: Startpage (and some newer engines) are not reliably blocked.
Blocking is incomplete: some results (top or sponsored) may still appear.
Block list size limits and performance issues as the list grows (sync can choke).

Recent reviews

most of my duckduckgo searches been littered with ai generated slop, especially automotive searches. theres so much! they bury all the legit human written content im looking for, especially forum posts specific to the car im working on. duckduckgo only lets me block up to 5 sites, this extension lets me block the other, at the moment, i got 200 sites in my blocklist and more to come. if you wanna store that many, go into settings and check the "use local storage instead off sync" option, after like 130 sites i ran out of sync quota haha
