A virtual interview with me

1. Give me a description of your general SEO experience.
   A. My experience is mainly with my own site at www.afreshpath.com and one other site www.qualitymotorsreno.com. So far, my site is on page one for narrow search terms involving outdoor recreation in Nevada. The other site has gone from not being listed at all in the first 10 pages of any search result to being in pages 2 and 3 of a couple of search engines. That work is ongoing at this time.
2. Can you write HTML code by hand?
   A. Yes I can. I do use some WYSIWYG editors and then modify the code by hand as needed.
3. Could you briefly explain the PageRank algorithm?
   A. In simple terms, Google uses the gross number of inbound links to a page to determine how important the page is. This "pagerank" has little to do with actual search results but can make a difference on user behavior.
4. Have you created any SEO tools either from scratch or pieced together from others?
   A. No, I do make use of many tools already available on the internet as well as SEO programs that I have purchased.
5. What do you think of PageRank?
   A. In relation to SEO projects, it is relatively unimportant but can give an indication of how much work needs to be done in gaining inbound links.
6. What do you think of using XML sitemaps?
   A. I use them. They are an additional tool to help the search engines when they crawl a site. There is no requirement for any sitemap and your pages will get indexed without them if you pay close attention to navigation within your site.
7. What SEO tools do you regularly use?
   A. Keyword analysis tools, keyword density tools, index checking, backlink checking, wordprocessor to check spelling and grammar, HTML validation and others.
8. Under what circumstances would you look to exclude pages from search engines using robots.txt vs meta robots tag?
   A. Usually I would use the robots.txt to keep a search engine from indexing an entire directory on a site. This would often be directories dealing with admin functions or directories that only contain script or image libraries.
9. What areas do you think are currently the most important in organically ranking a site?
   A. Text on page! Search engines utilize text and only text in providing search results. That text is found in many place including the URL and title of your pages as well as the visible text you place on your pages.
10. Do you have experience in copywriting and can you provide some writing samples?
    A. My experience in "copywriting" is limited to my site at www.afreshpath.com. It is a blog about outdoor recreation in Nevada and so far is placing well in search results.
11. Have you ever had something you've written reach the front-page of Digg? Sphinn? Or be Stumbled?
    A. Not yet! I am not particularly worried about it but I do try to write in such a way that others would be inticed to submit my articles.
12. Explain to me what META tags matter in today's world.
    A. The most important META tag for SEO is your page description. Search engines do make use of this tag but it does not outweigh the title or visible text. The META keywords tag is not much of a factor in the major search engines but should not be overlooked.
13. Explain various steps that you would take to optimize a website?
    A. 1. Interview website owner or webmaster to get a good grasp of the site's purpose and goals.
    2.     Perform a keyword analysis to find best performing keywords that should be used for that site and for individual pages of the site
    3.      Analyze site content to determine usage of relavant keywords and phrases. This includes visible text as well at titles, META tags, and "alt" attributes.
    4.      Examine site navigation
    5.      Determine the existence of robots.txt and sitemap and examine those for effectivenes.
    6.      Make recommendations for changes needed for the site and each individual page.
14. If the company whose site you've been workind for has decided to move all of its content to a new domain, what steps would you take?
    A. I would update the old site with permanent redirects to to new page for every page. Then I would attempt to remove old content from the major search engines to avoid duplicate content issues.
15. Rate from 1 to 10, tell me the most important "on page" elements
    A. #1 issue is visible text being relevant to expected search terms.
        # 2 would then be page titles
        # 3 is navigation and "alt" attributes for navigation items and link text.
        # 4 would be "alt" attributes for images and other media presented on pages.
16. What do you think about link buying?
    A. I discourage the practice for the most part. There are more effective means of paid marketing. One exception would be purchasing listings in highly reputable directories such as Yahoo directory.
17. What is Latent Semantic Analysis (LSI Indexing)?
    A. LSI indexing ries to overcome the limitations of "literal" search term matching . For example, if someone is searching for "hiking in Norhter Nevada" a literal search would only match the words used without taking into account words such as "hike", "hiked". LSI can give more relevant results because it does take word usage and context into account determining what a page is "about" rather than a strict reliance on literal wording.
18. What is Phrase Based Indexing and Retrieval and what roles does it play?
    A. In regards to search results, it is a method that search engines such as google use to determine relevance of a page based on phrases acutally used in a document. For example, if you have a page instructing people on wildlife photography, the search engine would reasonably expect to see terms and phrases such as "selecting a camera", "appraoching wildlife", and "low light photo conditions". Related phrases will add to the relevance of a page where unrelated phrases will reduce the relevance of a page. This is one technique that Google is using to weed out "spam" sites.
19. What is the difference between SEO and SEM?
    A. Seo is search engine optimization and is the process you use in getting your pages to place well on search results. SEM is search engine marketing and involves purchasing advertising space on search result pages. Sponsored listings are SEM. Both are related though! When using Google Adwords, the better you optimize your pages for search, the less you will be paying for your selected keywords in the PPC campaign and the better placment your ads will get.
20. What kind of strategies do you normally implement for backlinks?
    A. I check the competitors backlinks to find hightly relevant sites and request a link from them. If reciprocal linking is required, I may be able to place a lik back to them in a relevant portion of a page on the site but if not, I will state so and may not gain that link. Another method I use is to submit press releases to relevant media.
21. What role does social media play in an SEO strategy?
    A. Social media such as social networking sites and news sites can provide for viral marketing. Viral marketing has proven to be powerful if the content of a site is appealing.
22. What things wouldn't you to do increase rankings because the risk of penalty is too high?
    A. I would avoid any site with the appearance of a link farm. I would also avoid any "spam" practice such as unsolicited email campaigns, certain affiliate advertising sites, sites that re-direct visitors to your site, and anything resembling the practices of Zango.
23. Why might you want to use nofollow on an internal link?
    A. Many sites have shoping carts and member login or logout links. This type of link is simply an administrative function and does nothig to contribute to site content. The search engine does not need to index those pages.
24. Are you familiar with web analytics and what packages are your familiar with?
    A. Yes I am and the tool I use most frequently is Google's webmaster tools. I also use the available Yahoo hosting tools for my own sites. Knowing what search terms your visitors are actually using to find your site as well as where those visitors are coming from will help refine SEO efforts. The amount of time each visitor spends on your site will help in determining if content changes are needed.
25. From an analytics perspective, what is different between a user from organic search results vs. a type-in user?
    A  A user coming into your site from an organic search usually has never visited your site before or is performing a general search for a specific product or topic. These visitors are trying to find the site that most suits thier needs. A "type-in" user is specifally interested in your website. They may have found your URL in print advertising or from a friend. Often, these users are familiar with what you are offering and are coming back to your site as a repeat visitor.
26. How do you evaluate whether an SEO campaign is working?
    A. The main indicator is to perform a search on all major search engines using the keywords/ keyphrases I am optimizing for. An analysis of those results will help to determine if optimization has gained in the results or lost ground. This analysis should be done over time as each search engine will update and index on a varying schedule. Another aspect is to use website statistics to determine where traffic is originating.
27. What does competitive analysis mean to you and what techniques do you use?
    A. Competitive analysis means taking a close look at websites that rank highly in search results and comparing those sites to the one you are optimizing. They have employed methods that are working and are a valuable source for ideas.
28. If you've done 6 months of SEO for a site and yet there haven't been any improvements, how would you go about diagnosing the problem?
    A. I might approach the problem as if it were an entirely new project. Again taking a look at the keywords and phrases that I am attempting to optimize for and again taking a close inspection of top ranking competition. If the site is indexed and does show up in the irst 10 pages of a search but on in the top three, I would look into modification of major areas such as page titles, on page text, and page descriptions. If the site is not yet indexed or has been dropped from an index, there are major problems and the site may require a total re-work and re-submission.
29. How many target keywords should a site have?
    A. I advise not more than three or four well related keyword phrases. This allows for more effective optimization.
30. You hear a rumor that Google is weighting the HTML LAYER tag very heavily in ranking the relevance of its results - how does this affect your work?
    A. It doesn't unless the rumor proves to be fact. Yes, I check on the rumor but as with all rumors, it can have detrimental effects if you "jump on the band wagon" and it proves to be just a rumor with no basis in fact.
31. Why does Google rank Wikipedia for so many topics?
    A. Wikipedia is an established authority! As such, it is referenced by huge numbers of other documents with relevant text associated with links back to Wikipedia.
32. If salary and location were not an issue, who would you work for?
    A. Myself and only myself if those conditions existed.

SEO Interview Best Questions - Part II

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:

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.
