Don't you feel like it?

So much for the "interesting and unobtrusive" text links. I searched for "sun" – the star in fact – and look what I got:

So, the first "result" is actually an ad for a washing powder (litterally "Make sustainable savings With a dishwasher and Sun"). The ad on the right certainly looks like the usual 100%-free-singles-in-your-area scam ad you can find on whatever lousy porn sites. Please note at this point that I've never used Google – let alone customized personalized search – to search for porn nor meet singles (dishwashing powder ads in French neither BTW).

Seriously, who on God's green land would be tempted to click those links? No wonder so many people use adblockers TBH.

Cheers :)

I don't know too much about AdWords, but what I know is that those ads are not contextual. The advertisers wanted to display their ads when someone searches for Sun. If the CTR is very low, it means that they're either irrelevant, poorly-written or poorly-targeted (a French company has an ad for French people, but it targets the whole world) and Google will stop displaying them.

Below this thread, seen from Germany, there's also an ad for online dating... but it's not even tailored to the words in this thread. It appears below almost every thread. Unfortunately, these ads seem to be a kind of one-size-fits-all default when Google doesn't find something more precise. It seems that's because there's a huge market out there and online dating site advertisers invest huge budget in these. Perhaps it's also something getting relatively good click-thru rates on average independent of the topic...

Now that you've all used the words online dating, meet singles, etc. on this page they may be contextual here

but those ads have now vanished from the bottom of this page (California) no ads about dating at all :)

in the uk i get 2 relevant ads – one about selling your story to The Sun (a uk tabloid) and another by Sun Microsystems, the computer company.
