A search filter changes one search
A link that removes a panel or changes the order of results can feel like a permanent setting. Usually, it only changes the query you just sent.
What the URL does
A search form can send your query together with options in the URL. Google's Web filter, for example, opens a list of webpage links. It does not turn off AI Overviews across your account; a later ordinary search can show a different interface.
The same distinction applies to YouTube result filters. Choosing a video type in search does not remove it from the home feed, recommendations, or app.
Check the actual result
Run the same query once with the chosen filter and once from the search engine's ordinary page. Compare the selected tab, result types, and visible controls. If nothing changes, the parameter remaining in the URL is not proof that the service honored it.
Use a specific question rather than a broad word so you can distinguish a presentation change from normal result variation.
When a bookmark helps
If you often want the same kind of result, bookmark the tool page. It gives you a prepared form for the next query. The bookmark does not change your browser settings or make the filter the service's default.
For a lasting change, check the service's official settings. A URL parameter is not an account preference, and a shortcut that changes an open page may lose its effect after reloading.
Choose by the outcome
Want webpage links on Google? Use the Web filter. Want to reduce personalization for one query? Use that specific tool and compare the result. Want to alter an already open page? Use a browser shortcut, knowing its effect depends on that page.
The key distinction is simple: a search filter changes a query, a shortcut changes a loaded page, and a service setting may persist.
