N: 6 věcí, které by měl Google podle odborníků na SEO změnit

So, for example, if I'm linking to two websites here about gardening resources, A and B, both about gardening resources, and one of those comes from a botany site and the other one comes from a site about mobile gaming, well, all other things being true, it must be that the one about botany is going to provide a stronger link. That's just got to be the case.

Getting specific, targeting something like "gardening supplies" when I link to A, as opposed to on the same page saying something like, "Oh, this is also a good resource for gardening supplies," but all I linked with was the text "a good resource" over to B, that A is going to get a lot more ranking power. Again, all other things being equal, A will rank much higher than B, because this anchor text is still pretty influential. It has a fairly substantive effect.

So A301 redirects to B, versus C302 redirecting to D. Is it really the case that the people who run C plan to change where the redirect points in the future, and is it really the case that they do so more than A does with B? Well, a lot of the time, probably not. But it still is the case, and you can see plenty of examples of this happening out in the search results and out on the Web, that Google interprets this 301 as being a permanent redirect. All the link juice from A is going to pass right over to B.

Speaking of nudges and hints versus directives, rel="canonical" has been an interesting one. So when rel="canonical" first launched, what Google said about rel="canonical" is rel="canonical" is a hint to us, but we won't necessarily take it as gospel. Yet, every test we saw, even from those early launch days, was, man, they are taking it as gospel. You throw a rel="canonical" on a trusted site accidentally on every page and point it back to the homepage, Google suddenly doesn't index anything but the homepage. It's crazy.

And yet, with the exception of the two years where Google had a very direct partnership with Twitter and those tweets and indexation, all that kind of stuff was heavily influential for Google search results, since that partnership broke up, we haven't seen that again from Google. They've actually sort of backtracked on social, and they've kind of said, "Hey, you know, tweets, Facebook shares, likes, that kind of stuff, it doesn't directly impact rankings for everyone." Google+ being sort of an exception, especially in the personalized results. But even the tests we've done with Google+ for non-personalized results have appeared to do nothing, as yet.

When they did start cleaning up web spam, I think a lot of us thought, "Well, eventually they're going to get to PPC too." I don't mean pay-per-click. I mean porn, pills, and casino. But it turns out, as Matt Brown, from Moz, wisely and recently pointed out in his SearchLove presentation in Boston, that, yes, if you look at the search results around these categories, whatever it is -- Buy Cialis online, Texas hold-'em no limit poker, removed for content, because Whiteboard Friday is family-friendly, folks -- whatever the search is that you're performing in these spheres, this is actually kind of the early warning SERPS of the SEO world.
