Topic Sensitive TrustRank

I believe I found the paper on Topic Sensitive TrustRank [PDF] from Bill.

The thesis of the paper is that TrustRank is fundamentally flawed by being biased toward topical communities that are over represented in the seed set of trusted sites. Topics that are overrepresented in seed sets are often commercial in nature and also focused heavily upon by search spammers. Thus overweighting those seeds may also overweight many spammy topics and spammy pages.

By using a directory such as DMOZ or the Yahoo! Directory to offer seed sites and using those directory categories to categorize topic sensitive TrustRank scores the belief is that overall relevancy can be improved, while shifting the focus away from overrepresented topics that occur in a smaller seed set.

Since using DMOZ or the Yahoo! Directory as a seed set would vastly increase the seed set size it would be impractical to manually review all seeds, so you take the top half of trusted domains (as determined by topical TrustRank) from each topic to use as seeds. Weight the seed voting power by its PageRank and let this topic sensitive TrustRank happily propagate through the web.

Rabid Loyalty

I think one of the best parts of the SEO industry is the amount of questioning and curriosity that exists in the market. It really makes you see a wide array of the web as you search around because there is information in so many formats. You also start to see people attach to ideas that are 100% true while also seeing ideas spread that are 100% false.

What the false ideas spreading really show are how people become rabidly loyal, beyond question, toward certain people or ideas. If your website or product fill a niche where there is lots of discussion or it is easy for people to become rabidly loyal then it is going to be far easier to go from 0 to successful than if there is little discussion about your field. Does your marketing message or your field contain anything that makes it easy for people to be rabidly loyal?

Things people are rabidly loyal about include peanut butter and Firefox.

Things people are not rabidly loyal about include fruit cake and Flock.

Yahoo! Answers Integrated into Yahoo! SERPs

It might be a good idea to check out Yahoo! Answers. Yahoo! just integrated them into their SERPs.

You can see the integration on [best dog for apartment] and on the page footer of [Harley Davidson]

The Errors of Conventional Wisdom

A friend of mine and I recently chatted about a few examples of conventional wisdom being wrong. If you find new markets or marketing methods left untapped by people chasing saturated markets using techniques created by misguided group think you are in for making a boatload of cash. If you want to.

For a long time I had a few client sites and this one, but I felt I was perhaps starting to grow a bit inauthentic in my advice, relying too heavily on my brand, what friends told me, and what I read in forums without doing enough testing across a wide array of sites.

I recently bought a few more sites that I can use to test things on. I also partnered up as co-owner on a few sites. Fascinating what you can learn by doing things like tweaking internal link profiles and being aggressive on sites you can afford to lose, and seeing how quickly you can get to profitability in many different markets.

I am doing another major rewrite of my book. Hoping to send out an update notification sometime tomorrow or Monday. Sorry if I have been slow to replying to emails...trying to get the rewrite done.

Dan Thies Video on Links Again...

A while ago I posted about a web based Dan Thies video on links.

Dan recently released another free link video. Well worth a listen.

Link Building and LocalRank

Nothing new here, just mentioning the LocalRank patent from long ago. Claus Schmidt published a great article about LocalRank a couple years o.

The more interconnectivity there are amongst the top results the more algorithmic weight you could place on interconnectivity. Many search queries are not as competitive as they seem at first glance, because in some industries there are few industry hubs, so many of the high PageRank sites have little interconnectivity. If 10 to 20 of the top 200 results link at your site and only 2-3 link at most of the other top results it should not take much (if any) additional general authority to outrank competing sites.

Also keep in mind that pages which rank #50 for your main query may rank #2 or #3 for related queries, so links from top ranked and mid ranked related resources can be great in providing indirect value (ie ranking boosts) AND direct value (ie traffic). Some algorithms like these might make SEO harder if you use outdated techniques, but if you use current techniques it makes SEO easier because you do not have to deal with trying to get as many links if you are focused on getting the right links.

LocalRank sorta ties in with the concepts presented in Hilltop (brief overview of Hilltop here).

Keep in mind that if a site has enough authority it can rank well without needing much LocalRank, but getting links from related resources makes it easier for you to rank without needing to bulk up on building up tons and tons of PageRank.

I doubt Hilltop was implemented exactly as described in that paper (especially since I have many affiliated sites ranking next to each other in search results). Other biasing algorithms, like , likely allow Google to topically bias or personalize search results while perhaps still making it rather hard to manipulate them when compared with algoirthims such as Hilltop.

Google AdWords Traffic Estimator

Google made their AdWords traffic estimator available external to your AdWords account. They still use the evil little graphical representation for total search volume, but they give rough approximations in actual numbers for the amount of AdWords clicks they think you will receive.

The tool allows you to pass variables in the URL string, so perhaps this is good for scraping some data on the value of certain keyword markets? I also added a link to the tool on my keyword research tool.

If you do not enter a bid price or budget the bid price they recommend is supposed to show your ads ranking #1 85% of the time. More background here. They also note that when you access this tool external to your account that it will not factor in your past account performance, so the numbers may not be as accurate as if you use the tool in your account.

SEO Friendly Internet Explorer and Firefox Setups

I updated the page with Google Toolbar buttons for Internet Explorer, including a new botton for Google Trends.

I also listed the extensions I use on Firefox and posted a few handy Firefox bookmark toolbar links that you can drop to your Firefox bookmarks toolbar.

Recommending doing things like using the Google Toolbar assumes that you are not mass spamming on that computer or a computer that shares the same router / IP address.

Google Banned Link Finder

RustyBrick pointed out a new free SEO tool by Sufyan that searches through a page or site to look for links to sites that are banned in Google. It is designed for smaller to mid sized sites. The tool returns a list of pages you link at and their PageRank. The tool lists the age and URLs of pages that do not appear in Google.

Most large quality sites probably have at least a few links to banned sites, so you don't want to let Google become the editor of your site, but if most of your links go to banned sites that could hurt your site's reputation or ability to rank in Google.

Currently Google is also a bit flaky on the URL search. With some of them they they give the signs of sites being banned while listing many pages if you do a site: search.
