SEO Interview Questions - Part II

by TheMadHat on August 9, 2007

If you're new here, you must subscribe to my RSS feed, or I will hunt you down. Thanks for visiting!

My previous post on SEO interview questions I had a commenter ask where they could find the answers to these questions. Most of them are purposely open ended to get an idea of the level of experience and knowledge of your candidate. I will take the more specific ones and provide some explanations. I have also added an additional question not on the original post. If you are looking to hire or want to dazzle your prospective employers at an interview this post may be helpful.

8) What areas do you think are currently the most important in organically ranking a site?
Obviously a subjective answer, but domain trust, inbound links/anchor text, and properly formatted title tags are a good start.

10) What kind of strategies do you normally implement for backlinks? What do you think about link buying, link bait, and other specific backlink strategies?
There are too many correct answers for this one, so let’s go with the wrong answer: “Reciprocal link requests”

42) What is the Ultimate Answer to Life, the Universe, and Everything?
42 of course. If your candidate doesn’t know this please shoot him with the Point-of-view gun.

22) What is page segmentation? (ever heard of VIPS?)
VIPS is a research paper from Microsoft that stands for Vision-based Page Segmentation which is just an offshoot of the general topic of page segmentation. It is an analysis of how a user understands web layout structures based on visual perception and is independent from the underlying code and technologies. Each section of the page is segmented into blocks and different degrees of relevance are put on each block. This explains one reason why links in content areas are more heavily weighed than sidebar and navigational links (another reason is through the use of shingling algorithms, which I’ll get into on another question). Since this is a visual topic, I’ll give you a visual example from the research paper:

Vision-based Page Segmentation

23) What’s the difference between PageRank and Toolbar PageRank?
Internally PageRank is constantly updated while toolbar PageRank is updated every 2-3 months. Toolbar PageRank is a single digit integer while the internally calculated PageRank is more like a floating-point number. And the final answer: Who cares?

24) What is Latent Semantic Analysis (LSI - Indexing)?
The process of analyzing the relationships between terms in sets of documents. The engine looks not only at the query, but also looks for common terms in the document set. Documents that are semantically similar will carry more weight than those that are not. This is often a misunderstood concept.

25) What is Phrase Based Indexing and Retrieval and what roles does it play?
Phrase based indexing is used to classify good and bad phrases based on certain criteria inside the entire document. The number and proximity are taken into account. It also is capable of predicting the presence of other phrases on the page and will assign a higher or lower value depending on if those phrases or present or not.

26) In Google Lore - what are ‘Hilltop’, ‘Florida’, and ‘Big Daddy’?
Hilltop: An old and often contested algorithm that calculates PageRank based on expert documents and topical relevancy. The theory behind it was to decrease the possibility of manipulation from buying high PR links from off topic pages. This was implemented during the Florida update, which is our next topic.

Florida: The highly controversial update implemented by Google in November of 2003, much to the chagrin of many seasonal retail properties. There were several theories as to what was included in this update; Over optimization filter, competitive term filter, and the Hilltop algorithm. This update had catastrophic results on many web merchants.

Big Daddy: A test data center used by Google to preview algorithm changes. This information was made public around November of 2005 by Matt Cutts and allowed marketers to preview upcoming SERP’s.

What is a shingling algorithm and how is it used?
A shingling algorithm is a page segmentation method similar to VIPS, but less resource intensive and more likely to be used in search engine algorithms. These shingling algorithms look for blocks of content that do not occur frequently across a web site and look for blocks with certain desired features. When the engine stores this information, the navigational, advertisements, and other non-content areas are omitted. This increases speed, saves on storage space, and theoretically makes the results more relevant because of the increase in unique content.

Home Depot Makes Good

by TheMadHat on March 20, 2007

Back in January I posted a fairly extensive write-up about why Home Depot sucks at search marketing and as a follow up I figured I should point out that they know a thing or two about reputation management. Recently MSN featured an article about Home Depot shafting shoppers. There were thousands of responses to this article, the majority of them on the negative side. In order to control the damage a little, Home Depot CEO Frank Blake posted a response to all the negativity. Here are a couple excerpts from his post:

I’m Frank Blake, the new CEO for The Home Depot. I’ve read a number of the postings on the MSN message board (unfortunately, there were a lot of them), and we’ve dispatched a dedicated task force – working directly with me – that is ready and willing to address each and every issue raised on this board. Please give us the chance.

There’s no way I can express how sorry I am for all of the stories you shared. I recognize that many of you were loyal and dedicated shoppers of The Home Depot … and we let you down. That’s unacceptable. Customers are our company’s lifeblood – and the sole reason we have been able to build such a successful company is because of your support. The only way we’re going to continue to be successful is by regaining your trust and confidence … and we will do that.

I’d like to thank Scott – his column about our company was insightful and revealing. You can easily tell that it struck a nerve with me. Scott, we’ll do all in our power to again make The Home Depot the store you and your wife, Carolyn, once referred to as “our store.” I’d also like to give my thanks to the many people who posted comments on this board. We want them. We need them … to enable us to keep getting better. We’re committed to being the company that helped set the standard for customer service excellence in home improvement. Please continue to hold us accountable.

A very well done response in my book. He apologizes, addresses the concerns, lays out what they are going to do to fix them, and finally thanks the author and the responders for their feedback. He couldn’t have done a better job in my book. Way to go Home Depot! I’m off to buy some patio furniture.

CNN Is Worried About Page Views

by TheMadHat on February 14, 2007

So what’s the deal with CNN? I can’t figure out their intentions on this one. As Loren reported a few weeks back, Google now has snippets from RSS feeds appearing on the personalized home pages. CNN doesn’t let you see some of the snippets. I don’t know if it’s a lack of understanding on how they work, or they just want to jack up their page view numbers. When the snippets first appeared, all of the stories were displaying “Read full story for latest details” as seen below:

CNN No Snippet

Now some of the stories are showing the snippets:

CNN Snippet

What’s the deal CNN? Let’s go with one or the other. Page view numbers are soon to be an obsolete thing of the past anyway so just bite the bullet and use the snippets.

Home Depot Needs To Wake Up

by TheMadHat on January 23, 2007

I have received some positive feedback from my post on Blockbuster sucking at everything so I think I’m going to start a theme. Each week I’ll do at least one post slamming a company that should be on top of the game. Today’s example of “how your marketing executives don’t know crap” is Home Depot. **Sidebar: Home Depot didn’t make me mad like Blockbuster. Other than the fact it’s so big I get lost in it, Home Depot is a great store. They just are a little bit lost in the search arena.

Part 1: User Experience

Not to bad in this department. They have a fairly easy to use menu system. The number of categories they have is a little daunting, but they do a good job making the navigation intuitive. They have good descriptions and well written user reviews. The shopping cart and checkout process appear to be straight forward and don’t make me jump through any hoops (up to the customer information screen anyhow). The only glitch as far as this goes was the strange item recommendation they gave me. I put a DeWALT 3750 PSI Gas Pressure Washer with 13HP Honda Engine in my shopping cart. When I arrived at the cart page, there is an area that gives me more “items I might also like”. Since I’m buying a gas pressure washer I apparently might also like a Westinghouse 27 In. Widescreen LCD HDTV. Huh? Is this just a random product selection or something? Maybe they should think about building some product associations into the database. Or maybe I’m supposed to watch the TV through the living room window while I pressure wash the side of the house.

Part 2: Paid Search

We’re starting down a steep slope now. User experience was a B, paid search is a C-. I didn’t delve too deep into this area, and I’m not a contractor so I don’t know where you would normally find building supplies, but that’s the point. Your average home owner that wants to put up a fence might not be sure where to get supplies, so it’s reasonable to believe that they might go in and search for [lumber] or [fencing]. Nope, no ads and according to SpyFu they aren’t bidding on it. I know they have lumber at Home Depot, wish I could find out a little more. Okay, well I hired someone to build the fence, I’m going to lay the bricks for a patio. Where do I get the bricks? Let’s search. I type in [bricks] and I see the Home Depot ad…good deal. I click on it and where do I end up? Paving stone installation. That’s not what I was looking for people, see you later. I want to buy some bricks dammit. Just because eBay and Amazon bid on every word in the dictionary doesn’t mean it’s a good idea for everyone. If you don’t have bricks, don’t bid on it. Bid on [brick installation] and [patio installation] and those types of more targeted terms. Enough with the PPC, I gotta get to the good part.

Part 3: Organic Search

Paid search was a C-, organic search is an F+…if there is such a thing. Here’s where they really blow chunks. Like the kid from the Goonies. First off, look at this URL:

http://www.homedepot.com/prel80/HDUS/EN_US/diy_main/pg_diy.jsp?CNTTYPE=PROD_META&CNTKEY=
SuperFeatures2%2fAppliances%2fPM_Appliance_Promo3&cm_sp=creative-_-homepage-_-hero-_-applian
ces_super_10percoffenergystar_01162007&BV_SessionID=@@@@0992718361.1169532890@@@@&BV_E
ngineID=ccceaddjmhilddfcgelceffdfgidgnk.0&MID=9876&pos=p01

No, I am not making that up. Hello SEO 101…welcome to the show. Do I really need to say anything else about that one? Moving on, they have enough presence of mind to cloak the product pages. I take a look at the normal code for us users and what to my wandering eyes should appear? — frameset onload=”FramesetOnLoad();” Nice, so they have enough brains to properly cloak their pages, just not enough to come up with a more friendly solution than that or to fix the URL structure.

So Home Depot probably sells a lot of home appliances. Dishwashers, refrigerators and the like. Forget about the general terms like those, they aren’t anywhere to be seen. When users start the search for a home appliance, they are going to start with a more general term. They will narrow it down later to a model. Home Depot doesn’t start in the beginning of the search cycle, leaving that completely untouched. Fine, let’s say Mr. Customer has narrowed down his choices to a “Maytag Jetclean Dishwasher”. Since they have a whole page dedicated to this product, I’m thinking at least top five is where they should be. Maytag first, then it’s a shootout between Lowes, Home Depot, Sears, and maybe a couple others. No sir, wrong again. Position 37 in Google. Yea, everyone will find that. I’ve already driven to Sears before my browser even gets to page three. Okay, let’s get a little more detailed with our search in case Joe Schmoe still hasn’t found it elsewhere. “Maytag® Jetclean® II Convertible/Portable Dishwasher” copied right off their heading. Oops, bad news again. They are finally breaking page one but way down at the bottom. Granted there are some heavy weights in front of them like NextTag and Yahoo Shopping but they still should still be above the shopping portals…I mean they are the source, not the airplane catalog.

Even though I’ve probably burned my bridge to Home Depot, it would be nice to work for such a powerful company. Just think of the trust that homedepot.com has, and the ease of getting solid authority links. It seems anyone with a basic understanding of SEO could have this domain sitting at or near the top for just about everything they sell. The question is why they are sitting around letting this fall to the wayside.

Stay tuned next week, and if anyone has any ideas on more bridges I can take out let me know.

We all know to take everything read in forums with a grain of salt, and the majority of the time outrageous statements are debunked by more expert members. However, being an active participant of several “high quality” forums, there seems to be a lot of misinformation floating around, even among those who appear to be experienced marketers. Here are a few from just today, so lets take a look.

* The text content ratio is the percentage of the page which is actual content, as opposed to the portion which is HTML tags, scripts, etc… …search engines use this ratio to determine the relevancy of your page and the higher this value, the greater your chances of ranking higher.

Please go and find something better to do with your time. This may have had some significance long ago in a galaxy far, far away, but not since the dark ages. Basically you should take out all your style info and just use as much text as possible. In fact, just go and copy the Mortgage Encyclopedia and rank #1 for mortgages! Sweet, I’m quitting my job to go live on a sandy beach.

* yahoo prefers a KW density of 8 % but the synonyms are counted as the same keyword.

Google prefers 2 % KW density and synonyms are counted as different KWs.

Keyword density again. Sure. Seriously how did that person even come up with those numbers, much less how he could possibly argue that point.

* Sitewide external links will give your site a penalty. Put the links in the content area instead.

* Sitewide links to your own sites or any other sites are discounted to 1 link of value.

* Yeah,it’s not good to have outgoing links in one page, you can add the “nofollow” attribute to the links if you are afraid of the pr leak.

* Hi, on my site I am going to be having a few links to other sites and I’ve read that’s bad for PR.

Here we go with PR leakage as it relates to outbound links. Of course….don’t link to anywhere, we wouldn’t want to give away our precious PR. Then we have the “don’t use sitewide links” group…. Sitewide links sometimes make sense people, it doesn’t hurt anything (unless of course it’s to a bunch of bad neighborhood junk).

Moving on to the completely ignorant argument that a nofollow tag can help you keep your PR. I’m not sure how some of these things start circulating, but nofollow is to combat comment spam, not anything related to the mythical PR leakage. How well do you think a site with absolutely no outbound links is going to do? You can keep all your PR and rule the world. With the exception of something.com ranking for [something], I think you’ll find yourself sitting in a deep sandy box.

And what the hell does “discounted to 1 link of value” mean? One outbound link negates one inbound link? I don’t even want to speculate on that one.

* the title is very important, i would recommend having it on a white background

Say what? Google ranks pages with a white background and black text higher? Sweet, more money for my beach living.

So in conclusion, the secret to defeating Google is to have a white background, as much black text as possible, only paragraph tags, and no outbound links. Anyone want to join me for a Pina Colada?
