  4. 4. Why does technical SEO matter? It helps close the gap between web servers, search engines and human beings Source:
  5. 5. Content inventory Count your content, its conversion rates and the rate of publication and obsolescence The search operator “site:” can be used to get a rough estimate of the number of pages indexed by Google of a given website Compare the count of indexed pages of close competitors for the same target audience Root domain # pages indexed by 10,300,000 1,810,000 960,000 922,000 4,030 541 Table populated by querying Google for the count of indexed pages. E.g.:
  6. 6. Organization of the information
  7. 7. Organization of the information
  8. 8. Links as proxies to importance – PageRank algorithm
  9. 9. Value of a linked webpage Where p1,… p2, pN are the pages whose value we are determining, M (pj) is the set of pages that link to pi L (pj) is the number of outbound links on page pj N is the total number of pages

  11. 11. …not for web “page” Larry Page before his algorithm Larry Page after his algorithm Source:
  12. 12. Organization of the information
  13. 13. Simpler organization is more effective
  14. 14. Visualize the graph of your website Crawl with Xenu’s Link Sleuth (desktop application for Windows) Filter fields on a bash shell $ head crawl.txt $ cut -f1,2 crawl.txt | sed -e 's/http://www.{domain}.{tld}//g' -e 's/t/,/g' | grep -v ".jpg|http:|.css|.js" >filtered.csv $ head filtered.csv Visualize the network and analyze with Gephi
  15. 15. Graph – Example 1 Website of an annual event
  16. 16. Graph – Example 2 Website of a shopping website
  17. 17. The power of weak links Thin connections tend to link the clusters, allowing information to move between them Source: Giles, Jim. Making the links. Nature Aug 23rd 2012
  18. 18. Anatomy of a URL Friendly URLs need to bear in mind the URL encoding, the presence of delimiting characters and the organization of the information of the website. URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ] Example: Googlebot does not reach the optional last part of a URL for a document from the hash onwards. foo:// _/ ______________/_________/ _________/ __/ | | | | | scheme authority path query fragment | ___________________|_ / / urn:example:animal:ferret:nose
  19. 19. Topology of on-page links PageRank random surfer PageRank reasonable surfer
  20. 20. Single Page Applications Single Application Applications (SAP) pages free client browsers from querying web servers. SAP are now growing in use thanks to AJAX and frameworks like backbone and angular.js. This is a major challenge for search engines because the fragments in the URLs prevent crawlers to scrape the content. Google are asking webmasters to make their AJAX-based websites crawlable
  21. 21. Single Page Applications
  22. 22. SEO for Single Page Applications Modify the URL fragments for stateful AJAX pages!state Use a headless browser that outputs an HTML snapshot on your web server rather than a client machine Allow search engine crawlers to access these URLs by escaping the state Show the original URL to users in the search results
  23. 23. She is thinking keywords. Again.
  24. 24. A document's relevance given a user query Example: Query “SEO” on Match keyword Search engine optimization - Wikipedia, the free encyclopedia‎ Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's "natural" or un-paid ("organic") search SEO/BirdLife Se trata una federación de ámbito estatal de grupos territoriales, tiene como fines el estudio y la defensa de las aves y está integrada en la ONG mundial Co-ocurrence of keywords SEO <> search, search engine, website SEO <> aves, ONG TF*IDF (Term Frequency x Inverse Document Frequency) Topic modelling – Latent Dirichlet Allocation
  25. 25. TF*IDF tf–idf is the product of two statistics, term frequency and inverse document frequency With t the number of times that a term occurs in document d D the number of documents in the corpus denominator: number of documents where the term t appears
  26. 26. Latent Dirichlet Allocation LDA Source:
  27. 27. Topic modelling - LDA LDA based feature selection is reliable and generally better than document frequency based feature selection Source:
  28. 28. Structured data
  29. 29. Markup detected by Google Example of the webpage of an event - Structured Data Testing Tool
  30. 30. The section with a salmoncoloured background contains text links of Google Adwords “Normal” organic results, the second enjoys sitelinks for higher visibility and CTR Exceptionally visible organic result with itemised deep links thanks to Structured Data tagging
  31. 31. These are sitelinks – they are great for visitibility and CTR but you do not have prior control over them Note: Sitelinks can be removed via Google Webmasters Tools
