“The most famous part of our ranking algorithm is PageRank, an algorithm developed by Larry Page and Sergey Brin, who founded Google. PageRank is still in use today, but it is now a part of a much larger system.”PageRank may have distinguished Google as a search engine when it was founded in 1998; but given the rate of change Manber describes—launching “about 9 [improvements] per week on the average”—we’ve had a lot of opportunity to augment and refine our ranking systems over the last decade. PageRank is no longer—if it ever was—the be-all and end-all of ranking.
@fintan: We verified with Adobe that the textual content from legacy sites, such as those scripted with AS1 and AS2, can be indexed by our new algorithm.
@andrew, jonny m, erichazann, mike, ledge, stu, rex, blog, dis: For our July 1st launch, we didn't enable Flash indexing for Flash files embedded via SWFObject. We're now rolling out an update that enables support for common JavaScript techniques for embedding Flash, including SWFObject and SWFObject2.
@mike: At this time, content loaded dynamically from resource files is not indexed. We’ve noted this feature request from several webmasters -- look for this in a near future update.
Update on July 29, 1010: Please note that our ability to load external resources is live.
@captain cuisine: The text found in Flash files is treated similarly to text found in other files, such as HTML, PDFs, etc. If the Flash file is embedded in HTML (as many of the Flash files we find are), its content is associated with the parent URL and indexed as single entity.
@jeroen: Serving the same content in Flash and an alternate HTML version could cause us to find duplicate content. This won't cause a penalty -- we don’t lower a site in ranking because of duplicate content. Be aware, though, that search results will most likely only show one version, not both.
@All: We’re trying to serve users the most relevant results possible regardless of the file type. This means that standalone Flash, HTML with embedded Flash, HTML only, PDFs, etc., can all have the potential to be returned in search results.
@dsfdgsg: We’ve heard requests for deep linking (linking to specific content inside file) not just for Flash results, but also for other large documents and presentations. In the case of Flash, the ability to deep link will require additional functionality in Flash with which we integrate.
@All: The majority of the existing Flash files on the web are fine in regard to filesize. It shouldn’t be too much of a concern.
@brian, marcos, bharath: Regarding ActionScript, we’re able to find new links loaded through ActionScript. We explore Flash like a website visitor does, we do not decompile the SWF file. Unless you're making ActionScript visible to users, Google will not expose ActionScript code.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
@dlocks: We respect rel="nofollow" wherever we encounter it in HTML.

width
for container elements, we started using max-width
instead. In place of height
we used min-height
, so larger fonts or multi-line text don’t break the container’s boundaries. To prevent fixed width images “propping open” liquid columns, we apply the following CSS rule:img {
max-width: 100%;
}
<meta name="viewport" content="width=device-width, initial-scale=1">
device-width
in the region of 320px. If your mobile device actually has a width of 640 physical pixels, then a 320px wide image would be sized to the full width of the screen, using double the number of pixels in the process. This is also the reason why text looks so much crisper on the small screen – double the pixel density as compared to a standard desktop monitor. width
to device-width
in the viewport meta tag is that it updates when the user changes the orientation of their smartphone or tablet. Combining this with media queries allows you to tweak the layout as the user rotates their device:
@media screen and (min-width:480px) and (max-width:800px) {
/* Target landscape smartphones, portrait tablets, narrow desktops
*/
}
@media screen and (max-width:479px) {
/* Target portrait smartphones */
}
orientation
media query to target specific orientations without referencing pixel dimensions, where supported.
@media all and (orientation: landscape) {
/* Target device in landscape mode */
}
@media all and (orientation: portrait) {
/* Target device in portrait mode */
}
@media screen and (max-width: 800px) {
/* specific CSS */
}
@media screen and (max-width: 479px) {
/* specific CSS */
}
Our team shares a doc containing our current agenda and the previous meetings' agenda, minutes, and action items. In this meeting, we discussed:
- Feedback from blog post on Duplicate content due to scrapers. Some webmasters suggested that we could improve our detection. In order to improve quality, it would help to get feedback with specific examples. Susan Moskwa, one of our Webmaster Trends Analysts based in Kirkland, Washington, volunteered to post a blog comment to solicit more information.
- Recent and upcoming releases
- Webmaster Tools API on schedule
- "Skip intro" in search results
- JuneTune online chat agenda
- Two recent spam techniques mentioned in the blogosphere. Brian White, who leads one of the Webspam-fighting groups at Google, explained that one technique is new twist on old idea, both are already handled.
Matt provided feedback on:
- Proposal to write follow-up blog comment on duplicate content caused by scrapers to solicit specific examples. Approved.
- "URLs and case sensitivity basics" presentation for online chat

You may have noticed that we recently rewrote our article on What is an SEO? Does Google recommend them? Previously, the article had focused on warning people about common SEO scams to look out for, but didn't mention many of the valuable services that a helpful SEO can provide.
The article now notes some of the benefits of search engine optimization, and provides some guidance to site owners who are considering hiring an SEO. We'd also like to get your perspective: how would you define SEO? What questions would you ask a prospective SEO? What advice would you give to an inexperienced webmaster who's considering whether to contract an SEO? We'd like to hear your thoughts and incorporate your feedback if there's important advice that we should add.
