Search Engine Optimization

The Good and the Bad of SEO ’s From Google’s Mouth!

I recently had the opportunity to ask questions of some Google staffers. There were some questions I felt I needed to get verification on, so when I had the opportunity via a conference call I took it.

In this article I highlight some of the points made during the call so you know what Google thinks.

You know its bad when you take time from your holidays to come into work to attend a conference call. But that’s what I did a few weeks ago. You see I had to because I was going to have the opportunity to ask some Google employees specific questions on things that I’d been pretty sure about, but wanted to hear it right from the horses mouth.

The call lasted less than an hour, but in that time I found that there were many things I figured were indeed true. So lets start with the most obvious:

Is PageRank still important?

The short answer is yes� PageRank has always been important to Google. Naturally they couldn’t go into details but it is as I suspected. Google still uses the algorithm to help determine rankings. Where it falls in the algo mix, though, is up for speculation. My feeling however is that they’ve simply moved where the PageRank value is applied in the grand scheme of things. If you want to know what I think, be sure to read this article.

Are dynamic URLs bad?

Google says that a dynamic URL with 2 parameters should get indexed. When we pressed a bit on the issue we also found that URLs themselves don’t contribute too much to the overall ranking algorithms. In other words, a page named Page1.asp will likely perform as well as Keyword.asp.

The whole variable thing shouldn’t come as a surprise. It is true that Google will indeed index dynamic URLs and I’ve seen sites with as many as 4 variables get indexed. The difference however is that in almost all cases I’ve seen the static URLs outrank the dynamic URLs especially in highly competitive or even moderately competitive keyword spaces.

Is URL rewriting OK in Google’s eyes?

Again, the answer is yes, provided the URLs aren’t too long. While the length of the URL isn’t necessarily an issue, if they get extremely long they can cause problems.

In my experience, long rewritten URLs perform just fine. The important thing is the content on the page.

That was a common theme throughout the call� content is king. Sure optimized meta tags, effective interlinking and externalizing JavaScript all help, but in the end if the content isn’t there the site won’t do well.

Do you need to use the Google Sitemap tool?

If your site is already getting crawled effectively by Google you do not need to use the Google sitemap submission tool.

The sitemap submission tool was created by Google to provide a way for sites which normally do not get crawled effectively to now become indexed by Google.

My feeling here is that if you MUST use the Google sitemap to get your site indexed then you have some serious architectural issues to solve.

In other words, just because your pages get indexed via the sitemap doesn’t mean they will rank. In fact I’d bet you that they won’t rank because of those technical issues I mentioned above.

Here I’d recommend getting a free tool like Xenu and spider your site yourself. If Xenu has problems then you can almost be assured of Googlebot crawling problems. The nice thing with Xenu is that it can help you find those problems, such as broken links, so that you can fix them.

Once your site becomes fully crawlable by Xenu I can almost guarantee you that it will be crawlable and indexable by the major search engine spiders. Download it from http://home.snafu.de/tilman/xenulink.html

Does clean code make that much of a difference?

Again, the answer is yes. By externalizing any code you can and cleaning up things like tables you can greatly improve your site.

First, externalizing JavaScript and CSS helps reduce code bloat which makes the visible text more important. Your keyword density goes up which makes the page more authoritative.

Similarly, minimizing the use of tables also helps reduce the HTML to text ratio, making the text that much more important.

Also, as a tip, your visible text should appear as close to the top of your HTML code as possible. Sometimes this is difficult, however, as elements like top and left navigation appear first in the HTML. If this is the case, consider using CSS to reposition the text and those elements appropriately.

Do Keywords in the domain name harm or help you?

The short answer is neither. However too many keywords in a domain can set off flags for review. In other words blue-widgets.com won’t hurt you but discount-and-cheap-blue-and-red-widgets.com will likely raise flags and trigger a review.

Page naming follows similar rules ‘ while you can use keywords as page names, it doesn’t necessarily help (as I mentioned above) further, long names can cause reviews which will delay indexing.

How many links should you have on your sitemap?

Google recommends 100 links per page.

While I’ve seen pages with more links get indexed, it appears that it takes much longer. In other words, the first 100 links will get indexed right away, however it can take a few more months for Google to identify and follow any links greater than 100.

If your site is larger than 100 pages (as many are today) consider splitting up your sitemap into multiple pages which interlink with each other, or create a directory structure within your sitemap. This way you can have multiple sitemaps that are logically organized and will allow for complete indexing of your site.

Can Googlebot follow links in Flash or JavaScript

While Googlebot can identify links in JavaScript, it cannot follow those links. Nor can it follow links in Flash.

Therefore I recommend having your links elsewhere on the page. It is OK to have links in flash or JavaScript but you need to account for the crawlers not finding them. Therefore the use of a sitemap can help get those links found and crawled.

As alternatives I know there are menus which use JavaScript and CSS to output a very similar looking navigation system to what you commonly see with JavaScript navigation yet uses static hyperlinks which crawlers can follow. Therefore do a little research and you should be able to find a spiderable alternative to whatever type of navigation your site currently has.

Overall, while I didn’t learn anything earth shattering, it was good to get validation “from the horses mouth so to speak.

I guess it just goes to show you that there is enough information out there on the forums and blogs. The question becomes determine which of that information is valid and which isn’t. But that, I’m afraid, usually comes with time and experience.

Yet Another Process Monitor Manages Running Tasks

0 comments
Windows only: System monitoring utility Yet Another Process Monitor is not just a powerful way to see what's going on under the hood—it's also portable


Once you've


downloaded and extracted the no-installation-required software, you can put it on a flash drive or take it anywhere you'd like—so long as the target system has .NET Framework 2.0 installed. The utility can do everything you'd expect from a process manager, including a nice option to right-click a process and search the internet for more information.

There are plenty of more powerful features for the more tech-savvy, like detecting hidden processes, monitoring remote machines, and even viewing the memory of a process in a hex editor. Yet Another Process Monitor is free and open source, available for 32-bit Windows systems only.




Windows 7 upgraders guide: The simple version

0 comments


Microsoft released a nice, big chart the other day which details the many possible ways of moving from your existing Windows OS to Windows 7. It's got a slight case of information overload, however, so let's simplify things a bit. After all, not everyone reading Download Squad is an IT director with years of experience.




First, let's spell out the important terms.

In-Place Upgrade: means one you can run from your current Windows desktop. If f you currently own a laptop or desktop with Windows Vista Home Premium you will be able to boot up your computer as normal, pop in your Windows 7 Home Premium disk, and upgrade Windows. Your existing data (music, pictures, etc.) and programs are automatically moved.

Custom Install: "Custom" here really means "new," "fresh," or "clean." When you finish installing Windows your new desktop will be pretty bare - none of your old programs of data will be there, so you'll need to back them up first. Custom installs can't be performed from your existing Windows desktop. You have to force your system to boot from the Windows 7 DVD instead.

Arora: A light-weight, cross-platform web browser based on WebKit

0 comments


Arora is an open source
web browser that uses the same WebKit rendering engine found in Safari
and Google Chrome. But unlike those browsers, Arora is already capable
of running on Windows, Linux, and OS X, as well as a few other
platforms including FreeBSD.

That's because Arora is built to
work on any platform that supports the Qt toolkit.

The
browser has a couple of features that are all the rage with the kids
these days, including full page zoom (as opposed to text-only zooming),
and a private browsing mode that will let you surf without saving any
cookies or other personal data to the hard drive. It's also relatively
light on system resources, and boots and loads web pages reasonably
quickly.

World’s Largest Website

0 comments


There are a few contenders here, since defining what makes a website the largest is hard to agree on. First up is 28 Fields – apparently this is the world’s largest website, taking 120 days to download over a DSL connection. But since I don’t have that kind of time, I don’t know if this site is useful anyway.

For physical dimensions, it could be World’s Highest Website. Coming in at a moon-scraping 18,939 kilometers or 11,77 miles high.

For sheer number of pages hosted, you could argue that Google or Archive.org’s Wayback Machine holds that honour. Google has a cache of almost every page it indexes, which is a significant portion of the Web and Archive.org has historical caches of tons of pages.

can add translations for some of the languages.It looks smart and loads fast. it is
well organized now. Check it.
