@Scottsonline 1. The ease at which people are scamming Google with multiple sites that drive different keyword combinations on each site. Cheap Widget A on site A, Inexpensive Widget A on site B etc etc.
In the supply of real products and services particularly Google is driving the proliferation of sites and pages.
The problem is there's only one #1 slot, there's only one first page. Everyone wants to be at least on page one and then when you get there everyone wants to be #1. In my niche there are 50 real suppliers about 20 sites that try to get between Google and the real suppliers and hundreds of thousands of other pages that mention the product/service.
There seems to be three main strategies used by the 50 real suppliers.
1. Go with the sites that are getting between Google and you, ie give up on trying to rank top.
2. Try to get as many of those hundreds of thousands of pages to point to your site.
3. Make new sites and new pages to either point back to your main site or to rank for a particular term.
Or a combination of these.
This is only going to get worse. As sites designed to get between Google and real suppliers proliferate the real suppliers will have to do more to compete for the top slots.
I don't think that this is a function of the algo change or the more to caffeine it is simply coincidental.
When you think about it the number of real suppliers is only growing slowly. Google is causing the exponential growth of all of the crap making it ever harder for Google itself to find sites that offer what people really want.
