I used to be able to punch in a model number and come up with multiple CCTV dealers that sold the item I was looking for to buy. Recently my searches have produced Nextag, shop.dot.com and various other sites that take me to Ebay listings and other junk sites. What is going on with the searches as they no longer take me to sites that actually sell the items I am looking to buy. I could at one time recognize most of the first 20 listing as people I knew in the industry but no longer as they do not show at all.
What is going on?

Yep it is getting worse. Many spammers setting up websites, not providing any useful info just links to or text scraped from other sites, in some cases without the links. I dont search much now as its gotten so bad. The good old search engines from before google's time, provided better results.
