No, at the very beginning, Google only had the ads in little yellow boxes over to the right. They were very distinct. Then they started putting ads above the search results, but they still had a yellow background. Then they got rid of the background, but the results were still fairly visually distinct from the ads, and there would only be one or two ads above the search results. Now they just put this tiny little box that says "Ad" next to the ad, and they're no longer easily visually separable from search results. Also, very often the first screenful of results is entirely ads. The overall experience has massively degraded.
The other thing I've noticed is that more and more of the top results are from garbage content farms. Filtering this kind of crap out was the original reason Google existed and everyone switched to them, but they're failing at it now. IMO Google is overripe to be replaced with something better.
