In searches that bring up a forum listing, Google’s now showing additional forum threads below the main listing, like this:

The format is similar to Google Sitelinks, small links that sometimes appear below the main listing that shows at the top of a Google search results page or recently, within the description as well. Internally, Google calls this “forum clustering.” They been spotted earlier this month when in testing, and now they’re official.

Anchor Based Jump To Links or Sitelinks:

Snippet Based Jump To or Sitelinks:

Both these types of links take you to the same page of the main link, but they anchor you down or jump you to a specific point on the page. This is done using anchor links within the page source. The Google Webmaster Central Blog explains how webmasters can help gain these links in their snippets. Google explains:

First, ensure that long, multi-topic pages on your site are well-structured and broken into distinct logical sections. Second, ensure that each section has an associated anchor with a descriptive name (i.e., not just “Section 2.1″), and that your page includes a “table of contents” which links to the individual anchors. The new in-snippet links only appear for relevant queries, so you won’t see it on the results all the time — only when we think that a link to a section would be highly useful for a particular query.

As a side note, Google has also been testing what I am calling “deep sitelinks.” This is a combination of date and post data with Google Sitelinks in one snippet.

Google recently added anchor based Sitelinks, so this seems to be some sort of variation to that addition. I am not sure if I personally like the links in the snippet.

Hat tip to @rishil for sending this my way.

This seems to be some sort of extension of the one line site links or the product plusbox feature.

I will ask Google about this, but I expect the response to read something like, “We are continuously testing ways to improve the search experience with our search ads.”

Postscript: Here is the official Google statement on this test:

As part of our ongoing commitment to help users find the information they’re looking for online, we are testing a feature in which links to various pages of an advertiser’s website may appear within the text ads on Google.com. Presenting multiple landing page options is intended to make specific website information such as gift registries, special deals, store locators and the like more easily accessible to users. It also offers brand marketers a new way to quickly engage potential customers. This feature is currently in a limited beta with a small number of advertisers.

For example, a search for [charles darwin] in Google returns a Wikipedia result at the top. The result has the classic one line Sitelinks, but instead of the Sitelinks hyperlinking to different pages, they hyperlink to the same page, but anchor down the page to a specific section. For example, clicking on religious views anchors the searcher to the “Religious views” section on the page, by appending the # sign to the URL.

I believe Yahoo’s quick links have been doing this for a while now. Just try the same search for [charles darwin] but this time on Yahoo and clicking on the single link quick link to religious views, does the same thing.

Again, the one line sitelinks is not new, but the anchors feature seems to be new from a Google search page perspective.

In the past, sitelinks only showed below the No. 1 listing in the search results, and they typically appeared in two columns with up to eight total links. That won’t change, but moving forward, it’s also not the only way sitelinks will show up. There are two changes:

• Sitelinks might now show for several listings, not just the top listing on a search results page
• They might appear as a single row of up to four sitelinks, rather than in two columns

Google uses the example of a search for nutrition to show this in action:

You can continue to use Webmaster Central to block a page from appearing as a site link. Google says they’re speeding up the response to block requests, and planning to add the ability to block sitelinks that show up below pages other than your home page.

But Search Engine War noticed Google testing four sitelinks on a single line (one column), directly under the snippet and above the display URL. They have a picture, which I seem to not be able to reproduce here.

What I find interesting is that this format is one the the earliest test implementations of Google Sitelinks, even before they were named Sitelinks.

Enhanced Listings

The most dramatic of the changes involving reviews of products and services that appear on Yelp, Citysearch, CNET, TripAdvisor and Download.com. The system, which Google has yet to give an official name, allows these publishers to flag data on their web pages that can be extracted and shown within the page’s description in search results. For example:

In the screenshot, you can see how after the page description for this restaurant review on Citysearch, there’s a separate line that allows for a price range to be shown, the number of reviews from Citysearch members and the overall “star” rating of the restaurant.

Behind the scenes, Citysearch is embedding the information for Google to extract within the page itself, using code like this:

<PageMap>
<DataObject type="item">
<Attribute  name="name">Hide Sushi</Attribute>
<Attribute  name="category">Sushi, Japanese, Restaurant</Attribute>
<Attribute name="pricerange">$$</Attribute>
</DataObject>
<DataObject type="review">
<Attribute  name="summary">No fuss, just fish at this neighborhood favorite  get-it-to-go sushi spot.</Attribute>
<Attribute  name="ratingstars">4.5/5</Attribute>
<Attribute  name="ratingcount">55</Attribute>
<Attribute  name="reviewdate">11/26/2008</Attribute>
</DataObject>
</PageMap>

See how the sections in bold correspond to the actual description shown (summary), the price range (pricerange), the number of reviews (ratingcount) and average rating (ratingstars). Any page from one of five test sites using these and other attributes have their descriptions enhanced with the information.

These enhanced listings are similar to Yahoo’s Search Monkey product and part of a continuing trend for search listings to show more than the standard title, description and URL of a web page.

Should you go out and start marking up your pages now? I wouldn’t bother. Right now, enhanced listings at Google only work for the sites in the test program. It won’t help other sites. In addition, the syntax might change or be supplemented with the ability to use standard Microformats.

Supporting Microformats or some way of tagging existing information within a web page would be great. While Yahoo also supports Microformats (and other tagging methods), these still require a developer to go through and create an application that enhances the result.

With Google’s system, no developer knowledge would be required. If you know that a price range is on your existing page, and you add a small bit of HTML code that says in someway to Google “this is the price range,” that’s it — your listing will be enhanced automatically (in cases where Google chooses to do it).

So for now, sit tight until Google announces official support — if they do at all. This remains an experiment that might not go forward as a permanent feature. And no, the enhanced listings will not help boost rankings. Google says the changes are purely a display feature.’

How can you see these enhanced results when searching? You have to be lucky. Right now, they’re only being shown to a select group of searchers picked randomly from those who visit Google who are also in the US. If the experiment is deemed successful, then everyone might see them in the future.

Pagelinks

Another experiment that impacts page descriptions also has no official name, so I’ll give it one — Pagelinks.

We already have something similar to these from Google called Sitelinks. These are the navigational links that appear under a web site’s listing, if it appears in the number one spot. Here’s how they look:

Sitelinks have been out there for ages. Just over a year ago, Google even introduced a way for site owners to control Google Sitelinks to some degree, for their own listings.

When you click on a Sitelink, you are jumped to other pages within the same web site that the listing comes from, key areas that Google thinks are of interest. So what’s different with Pagelinks? Look at the screenshots below:

Notice how there are links after the words “Jump to” right at the beginning of the snippet, embedded in the description? Click on these, and you’ll jump to a place within the page that listed, rather to a completely different page within the site.

Get it? Sitelinks jump you to various places within a particular web site. Pagelinks jump to spots within a particular page itself.

How do you get these? There’s nothing you can do other than to have pages that contain internal anchor links. Don’t know what those are? Look at this page from Wikipedia, which is one of the screenshots above. Scroll down, and you’ll see the Contents area where if you click on a link, that jumps to other places within the page. That’s an anchor link — it jumps you within a page, rather than out of it.

If your page has internal anchors, that makes it eligible to have Pagelinks. Unlike Sitelinks, Pagelinks may show up in descriptions regardless of where a page is listed — Sitelinks only show for pages in the number one spot. And why does a description get a Pagelink and which exact link is selected? Google simply said that it is working on the algorithm that controls all this.

Should you go out and start adding internal anchors? I would do this only if it already makes sense to help your users that need to navigate within a particularly long page. Keep in mind that right now, only a sample of Google searches even see Pagelinks. The experiment might be discontinued. If successful, I think it’s likely we’ll see Pagelinks control come along similar to Sitelinks control. So I’d be in watch-and-see mode, for the moment.

Automatic Spelling Correction

Another change is auto-spelling correction. For years, Google’s offered spelling corrections, the largely much loved “Did you mean” link that appears if you misspell a word. But consider what I see (and some other may see) for larry pge:

See how the “Did you mean” message comes up followed by the words “Top 2 results shown.” What Google is doing is automatically showing you the first two results for the correct spelling [larry page] and then showing the remaining results for [larry pge].

Why make the change?

“This approach gets users to the results they wanted faster. Showing the results of the original query accounts for cases when query correction was undesired,” said Johanna Wright, director of product management at Google.

I think it’s a good change. There was a time when some search engines just automatically corrected spelling, which can seem like the right thing to do, but I always found it kind of annoying. This is a good compromise.

Unlike the other changes, this isn’t an experiment but instead a permanent change being rolled out. Everyone should see it within the next week or two.

In a somewhat related set of experiments, Google’s also testing ads, links and answers within its Google Suggest service. See our separate story, Google Search Suggest Get Ads, Links & Answers, for more about that.

For example, Sam at Oh! Nuts emailed me a screen shot of Google showing his URL in the Google Suggestions for when he typed in [oh nut], here is a screen capture:

I was unable to reproduce this myself in Safari, Firefox, Chrome or Internet Explorer – but Sam told me he is only able to see this in Internet Explorer. I assume “navigational queries” would all do something similar to do, so if you type in [search engine la] Google would show a suggestion for [search engine land] and append at the end, the URL.

To me, this seems to be an extension of Sitelinks, but within Google Suggest.

The answers are on image search ranking, Sitelinks, reconsideration requests, redirects and communication. I am not going to go through each with my analysis, because I already did that at the Search Engine Roundtable.

Here are my analysis posts at the Search Engine Roundtable on each thread:

• Google Answers: Why Are My Images Missing From Google? related to image search ranking.
• When Should I Submit a Reinclusion Request to Google? related to reconsideration requests.
• 2008 Guide to Google & Webmaster Communication related to how Google sends you messages.
• Using Redirects to Move Your Site to a New Domain related to the redirects thread.
• Why Don’t My Sitelinks on Google.com Match My Webmaster Tools Sitelinks? related to the Sitemaps thread, which I found to be the most interesting information.
