Last week Google's Matt Cutts gave an
interview in which he revealed some things that will help webmasters to
better optimize their websites. Here are the most important things that Matt
Cutts said in the interview:
1. The more relevant links you have, the more pages of your site will be
indexed
Matt Cutts said that the number of pages that Google indexes from your
website is roughly proportional to the PageRank of your website. That means that
more pages of your website will be indexed if your website has many inbound
links.
Google does not have an indexation cap, i.e. they will index all pages of
your website if you have enough inbound links. Remember that the PageRank that
Google uses in its ranking algorithm is not the PageRank that is displayed in
Google's toolbar.
2. Slow servers can cause problems
If Google can only crawl two pages at any given time due to a slow server,
Google can set some sort of upper bound on how many pages they will fetch from
that host server. This can be a problem for websites that are hosted on shared
or slow servers.
3. Duplicate content can cause problems
"Imagine we crawl three pages from a site, and then we discover that the
two other pages were duplicates of the third page. We'll drop two out of the
three pages and keep only one, and that?s why it looks like it has less good
content."
As mentioned above, Google will index your web pages based on the PageRank of
your pages. If you have duplicate content, some pages of your website will be
discarded and you'll waste ranking opportunities.
Matt Cutts also indicated that if you link from one page to a duplicate page,
you can mess up your PageRank. Google also tries to pass the PageRank and other
link signals from the duplicate pages to the original page.
If you use the rel=canonical tag on your web pages then the pages needn't be
exact duplicates but they should be conceptual duplicates of the same product,
or things that are closely related.
"It's totally fine for a page to link to itself with rel=canonical, and
it's also totally fine, at least with Google, to have rel=canonical on every
page on your site."
However, Google does not always obey the canonical tag:
"The crawling and indexing team wants to reserve the ultimate right to
determine if the site owner is accidentally shooting themselves in the foot and
not listen to the rel=canonical tag."
4. Affiliate pages don't get high rankings
If a website is an affiliate website that is very similar to other pages
(only with a different logo, etc.) then this page won't get high rankings.
If Google detects an affiliate link than this link won't pass any PageRank
power.
5. Redirects work but they don't pass the whole PageRank
If you change your domain name and redirect old pages with a 301 redirect
from your old page to your new page then the link power will be passed to your
new domain name but the overall power of the links will decrease. 301 redirects
do not pass the full PageRank.
6. Low quality pages can cause problems
"If there are a large number of pages that we consider low value, then we
might not crawl quite as many pages from that site, but that is independent of
rel=canonical."
If you have a lot of web pages with thin content then Google might stop
crawling your website. Matt Cutts also suggested that it might help to be wordy:
"You really want to have most of your pages have actual products with lots
of text on them."
7. PageRank sculpting and website navigation
Google does not want you to sculpt your website for PageRank reasons. The
best way to pass link power from one page to other pages is to have a good
website navigation.
"Site architecture, how you make links and structure appear on a page in a
way to get the most people to the products that you want them to see, is really
a better way to approach it then trying to do individual sculpting of PageRank
on links."
"You can distribute that PageRank very carefully between related products,
and use related links straight to your product pages rather than into your
navigation. I think there are ways to do that without necessarily going towards
trying to sculpt PageRank."
8. You still shouldn't use JavaScript links for your website navigation
"For a while, we were scanning within JavaScript, and we were looking for
links. Google has gotten smarter about JavaScript and can execute some
JavaScript.
I wouldn't say that we execute all JavaScript, so there are some
conditions in which we don?t execute JavaScript.
We do have the ability to execute a large fraction of JavaScript when we
need or want to. One thing to bear in mind if you are advertising via JavaScript
is that you can use NoFollow on JavaScript links."
9. Google does not like paid links
Matt Cutts said they Google doesn't want advertisements to affect search
engine rankings.
They might put out a call for people to report more about link spam in the
coming months. Matt Cutts said that Google "does a lot of stuff" to try to
detect ads and make sure that they don't unduly affect search engines.
If you want to get high rankings on Google, you should use search engine
optimization
methods that lead to lasting results. Don't try to cheat Google.
