I usually look at the first page and if there aren't any relevant stuff but an irrelevant stuff is repeated (for example 'shop' or 'buy'), I try to add these repeated words with a negative sign. Then if a synonym of the annoying word starts to flood the results, I get pissed off badly....

Anyhoo, I'm curious about your tech site, mind sharing a link?

but I will be worrying if most people use 10 per page.

Majority of users will click only the first link.

No, really.

I use 10 per page. I don't just click the first link, but I generally visually scan the first 5 or 6, looking at the synopses that best match what I'm looking for, and will open any seemingly useful links (usually 3) on a new tab before going through them. If the tab isn't what I'm wanting, I close the tab and move on to the next one. If I close all the tabs. that automatically brings me back to the tab open with the google search, in which case I either go to the second page, or try a different search query.
[/quote]I think we should clarify what kind of search people are doing.

A lot of the time, people are searching for something that has one specific answer - e.g., a website of a company, organisation or whatever. The reason why most people only click the first link, is because the first link is the correct answer. If sometime types gamedev, and this site comes top, why look at any of the other results?

Speculative search is a different matter - e.g., if someone is searching for programming websites. Is it still true that the majority won't look further than the first link?

That's the good reason why I was asking for tech guys' opinion.
Different crowd has different habits and requirements on searching, IMO.
