The impression I had was that Google has basically high-jacked it though, and many of the third-party ads seemed to have little or connection with engineering..
That's likely down to your browsing profile (or lack thereof)…
Almost every Google ad I see on the site when browsing on my phone or personal laptop is engineering related.
…
Unlikely that Google hijacked it, though it is possible that the site was hacked. Just tried lathes.co,uk to see where the ads were coming from and although my blocker zapped 51 links, they don't appear when I turn the blocker off, though the layout isn't quite normal. Could be because the site owner is busy fixing the problem!
Two basic ways a web-site can host adverts:
- It can store and serve them just like any other content. Forum Members ads are managed this way, as are most of the commercial ads on screen right. Site admin controls these, but behind the scenes there will be an administrator selling space, collecting fees etc. Could be a part time job on a small site, or a big team on a popular website. As admin is expensive and unpopular, it's common to outsource it, with some loss of control.
- Most web advertising is served by third-party specialists, not by individual websites. The website attracts people by publishing something of interest and because this costs money, there is usually some way of recovering the costs, often advertising. Instead of the website owner hosting and administering adverts himself, he embeds links to a third-party ad-server. When the link is activated by a user, the ad-server dispenses an advert, counts clicks, does all the admin, and dispenses the money. As it services many websites, it can track users, and sell or buy similar data from other ad-vendors.
So an ad could be:
- provided by the website owner, or.
- dispensed by a third-party:
- randomly, or
- targetted on the individual based on cookies left on his system by other websites, or
- targetted on the individual based on a profile built over time by tracking his internet activity over a long time, probably from multiple services.
There are layers of sophistication in ad-serving. For example, advertisers will pay extra to get themselves promoted on a popular web-site used by the sort of well-heeled people who buy their products. As there is hot competition to advertise on popular websites, it's possible for ad-servers to auction ad-space on the fly, getting the best price per click for the website owner. Done by software: those wishing to place an ad run code to analyse the users profile and calculate how much putting an advert on his screen is worth to them. Highest bidder wins. For example a US vendor would pay more for an advert if user's profile revealed previous enthusiastic buying in the US, and might not bid at all with an casual cheapskate outside the US.
Another approach is to shotgun blast users with adverts in the hope that one of them will hit the target. This approach is extremely annoying and it's probably the main reason most people install ad-blockers, and only enable ads on sites they approve of. (I'm using Firefox with AdBlocker Ultimate)
This being an imperfect world, these systems aren't 100% effective and they can be abused. In the past I mentioned lathes.co.uk emitted a clue that security of its information section wasn't top-priority, and such simple clues attract evil-doers looking for an easy score. (The shop part was better secured.) Maybe Tony decided to make money by advertising and allowed too many, maybe he's the victim of a cuckoo hacker using him as a free advertising springboard. There are other possibilities, we may never know…
