Google’s new Google Sitemaps service, a free inclusion service, is a step in the right direction, but there are two quite major problems with Google’s approach.

Last Friday it seemed like the whole blogosphere was abuzz with the news that Google unveiled its new Google Sitemaps service, a free inclusion service where you publish an XML file of your site pages to Google so its spider can get a better sense of what to crawl of your site. This is good news, especially for dynamic sites that aren’t getting fully indexed. I appreciate Google once again showing its thought leadership. Not only is Google giving webmasters a new way to relay information about their site structure information to its spiders, but it’s sharing this new technology with the other search engines by releasing the protocol and code as open source.

This all sounds wonderful, but there are 2 quite major problems with Google’s approach.

• First, it doesn’t solve the duplicate pages problem that a great many dynamic sites have. Even the Google Store suffers from this (which I blogged about previously but here’s a more recent example of a Google Store product page being duplicated times in Google’s index). The Google Sitemaps protocol does not provide a way for webmasters to convey which pages are duplicates of other pages. A site that gets crawled incorrectly by Googlebot, due to superfluous or non-essential parameters/flags being included in the URLs of links on the pages, will continue to get crawled incorrectly. An “Official Google Sitemaps Team Member” states that the sitemap XML file will merely augment their crawl, it won’t replace existing pages in the index:
  

  This program is a complement to, not a replacement of, the regular crawl. The benefit of Sitemaps is two fold:
  – For links we already know about thro our regular spidering, we plan to use the metadata you supply (e.g., lastmod date, changefreq, etc.) to improve how we crawl your site.
  – For the links we dont know about, we plan to use the additional links you supply, to increase our crawl coverage.

  The high-level Google engineer who goes by GoogleGuy in the online forums explains Google Sitemaps in this way:

  Imagine if you have pages A, B, and C on your site. We find pages A and B through our normal web crawl of your links. Then you build a sitemap and list the pages B and C. Now there’s a chance (but not a promise) that we’ll crawl page C. We won’t drop page A just because you didn’t list it in your sitemap. And just because you listed a page that we didn’t know about doesn’t guarantee that we’ll crawl it. But if for some reason we didn’t see any links to C, or maybe we knew about page C but the url was rejected for having too many parameters or some other reason, now there’s a chance that we’ll crawl that page C.

  So, the way I read GoogleGuy’s explanation, if pages A and C are essentially duplicates of each other, with A containing an additional superfluous parameter in its URL (like sortby=default or lang=english), then BOTH could end up in Google’s index. Thus, Google Sitemaps won’t reduce the amount of duplication in Google’s index; in fact, I believe it will increase it.

  Duplicate pages, on its own, may not sound like a problem for webmasters as much as it is for Google itself, which has to dedicate additional resources to maintain all this redundant content in its index. However, it does have serious implications for webmasters, because it results in PageRank dilution ?Į where multiple versions of a page split up the “votes” (links) and PageRank score that a single version of the page would aggregate.

• This brings me to the second, related problem with Google Sitemaps: it doesn’t do anything to alleviate the phenomenon of PageRank dilution. PageRank dilution results in lower PageRank, which in turn results in lower rankings. For example, consider that the above-mentioned Google Store’s product page (the “Black is Back T-Shirt”) is in Google’s index 5 times instead of just once. So each of those 5 variations earns only a fraction of the total potential PageRank score that it could have earned if all the links pointed to a single “Black is Back T-Shirt” page.Google Sitemaps needs to provide a way to convey, or to sync up with, the site’s hierarchical internal linking structure, so that it’s clear which pages should get how much of a share of the PageRank flowing into the site’s home page. Since the primary holder of PageRank score is the home page (that is, after all, the page that most everyone links to), it’s up to the site’s internal hierarchical linking structure to pass the PageRank of the home page to the rest of the site. As such, a page that is 2 clicks away from the home page will get a much larger share of PageRank score passed on to it from the home page, versus a page that is 5 clicks away from the home page.

Here’s how I suggest both of the above issues be rectified: by extending robots.txt with some additional directives that specify:

• which parameter in a dynamic URL is the “key field”
• which parameter is the product ID and which is the category ID (specifically for online catalogs)
• which parameters are superfluous or that don’t signficantly vary the content displayed

Armed with this information, Googlebot will be able to not only eliminate duplicate pages but also intelligently choose the most appropriate version to save in its index and then associate with that page the PageRank of ALL versions of the page. The days of session IDs killing a site’s Google visibility would be over! Google admits in its Sitemaps FAQ that session IDs are still a problem even with the advent of Google Sitemaps:

Q: URLs on my site have session IDs in them. Do I need to remove them?

Yes. Including session IDs in URLs may result in incomplete and redundant crawling of your site.

Remember, getting indexed only gets you to the party, it doesn’t mean you’re going to be popular at the party. Google Sitemaps may help you get more pages indexed, but if those pages all have a PageRank score of 0, then what was the point? It’ll be like sitting along the wall the whole time with no one asking you to dance!

GravityStream, our SEO proxy technology (the concept of SEO proxies is explained in my article in Catalog Age last October) deals with PageRank dilution by distilling URLs in links into their lowest common denominator and replacing them on the proxy. We’ve found that, even as Googlebot gets more aggressive at spidering dynamic sites with complex URLs and starts indexing one of our clients’ sites more fully, our proxy still has a major leg-up on the native site that it’s proxying. For example, our GravityStream proxy of PETsMART.com is #1 in Google for “best pet toys”, and yet the corresponding page on the PETsMART.com native site is nowhere in the first 10 pages of results even though it is indexed. Until Google extends Google Sitemaps to deal with PageRank dilution, I’d expect that a GravityStream proxy will still trump a native site, even if it’s using Google Sitemaps. That means that currently, despite Google Sitemaps, GravityStream still plays an important role for online retailers. Nonetheless, it’s my sincere hope that Google takes my feedback on board and reworks their protocol!

Blogging is one of the hottest trends on the web. A new blog is created every 5.8 seconds but, curiously, catalogers and retailers are notably absent from the “blogosphere” — the online blogging world. By lagging behind on this new trend, they’re missing a key opportunity to actively participate in the global online conversation that’s now happening without them.

You can’t just ask a Search Engine Optimization vendor if they are ethical. Of course they will say “yes.” So if you are shopping for some SEO help, how do you screen out the baddies?

A while back I blogged about how to be objective with your SEO vendor selection, but I didn’t specifically cover how to screen out the unethical ones. I will do that now.

First off, interview the vendor extensively. Get them to explain the techniques they will be using. A “yes” from them to any of the following questions is a warning sign:

• Do your techniques involve any kind of deception?
• Do you use proprietary techniques?
• Do you use doorway pages or anything similar?
• Do you do deceptive redirects?
• Have you ever had sites banned?
• Do you offer rank guarantees? (You can?Ĵt guarantee something you have no control over. The only way you can get a guaranteed rank is through pay-per-click.)
• Do you send email to prospects with whom they do not have a prior existing business relationship or permission from those prospects in advance? (If so, that’s spam! Never do business with a spammer.)

During your discussions with the vendor, if they describe their SEO tactics as short-term, you might want to reconsider. SEO, when done right (i.e. when following “best practices”), has long-term sustainable impact ?Į for years, in fact. For proof, just read this.

After you’re done quizzing the vendor, talk to their clients. Ask those clients:

• Does your SEO vendor teach you how to fish, or do they always do the fishing for you?
• Have your traffic and sales gone up a lot because of the vendor? If so, do you believe the increase to be sustainable?
• How long have you worked with the vendor? How long do you plan to continue working with them? Any idea what the vendor’s client churn rate is?

Then you’ll need to do some of your own investigating. Check the HTML code on their clients’ sites for hidden text, hidden links, and so forth. Also examine what their clients’ websites are serving to the search engines. There are a couple different ways to view a website through the eyes of a search engine spider: one is through a Firefox browser extension called User Agent Switcher; the other is through the cached version of the page that was indexed by the engine, available from the Cached link in the search results. Compare and contrast the page meant for the search engines to that corresponding page off the native website as seen by a normal visitor. If the content served up to the search engines is something completely different than what is served up to visitors, then they are spamming. Things to look for when making your comparison: if the title tag is significantly different, and if keywords have been stuffed into the body copy, the meta tags, and into parts of the website to help the version that was shown to search engines rank better. Finally, search the online forums and SEO directories like SEOPros.com and SEOConsultants.com with Google for complaints about the vendor.

There has been plenty of discussion in the blogosphere about blogs and search engine optimization (SEO). Google in particular seems to love blogs. Blogs are rich in content, heavily linked, with links that tend to be contextual, and without much in the way of code bloat or gratuitous flash animation. In short, blogs are search engine friendly out-of-the-box.

But what about SEO’ing a podcast, the blog’s newest cousin?

Podcasting (where anyone can become an Internet radio talk show host or DJ) presents unique opportunities to the marketer/content producer that blogging does not. I expound on this a bit more in my recent MarketingProfs article but the benefits of podcasting from an SEO standpoint wouldn’t seem as obvious. Podcasts are usually audio content, so you don’t get all this rich textual content that the search engine spiders can snarf up. You also don’t get the rich inter-linking that happens with blogs because you can’t embed clickable URLs throughout your MP3 files.

Nonetheless, I believe you can SEO your podcasts. Here’s how:

1. Come up with a name for your podcast show that is rich with relevant heavily searched-on keywords.
2. Make sure your MP3 files have really good ID3 tags ?Į rich with relevant keywords. ID3V2 even supports comment and URL fields. The major search engines may not pick up the ID3 tags now, but they will! And besides, there are specialty engines and software tools that already do.
3. Synopsize each podcast show in text and blog that. Put your most important keywords as high up in the blog post as possible but still keep it readable and interesting.
4. Encourage those who link directly to your MP3 file to also link to your blog post about the podcast.
5. Consider using a transcription service to transcribe your podcast or at least excerpts of it for use as search engine fodder. Break the transcript up into sections. Make sure each section is on a separate web page and each separate web page has a great keyword-rich title relating to that segment of the podcast. And, of course, link to the podcast MP3 from those web pages. There are many transcription services out there, where you can just email them the MP3 file or give them an URL and they send you back a Word document. Here’s a partial list of transcription services .
6. Submit your podcast site to podcast directories and search engines such as audio.weblogs.com.
7. Let people in your industry, such as bloggers and the media, know that you have a podcast because podcasting is quite new and novel. It will be more newsworthy and linkworthy than just another blog in your industry.
8. Don’t just get up on your soapbox. Have conversations with others, in the form of recorded phone interviews, and podcast those as well. Pick people who have great reputations on the web and great PageRank scores, and ask that they link to your site and to your podcast summary page.

This isn’t meant to be a comprehensive list of tactics. It is simply meant as a catalyst for creative thinking. SEO, in particular the link building aspect, isn’t about just following a set list of formulae. It is about creatively thinking outside the box and differentiating yourself in ways that make your site eminently more linkworthy than your competitors.
