  • 14.

  • 15. Graph – Example 1 Website of an annual event

  • 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. 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://example.com:8042/over/there?name=ferret#nose _/ ______________/_________/ _________/ __/ | | | | | scheme authority path query fragment | ___________________|_ / / urn:example:animal:ferret:nose
  • 19. Topology of on-page links PageRank random surfer PageRank reasonable surfer
  • 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. Single Page Applications
  • 22. SEO for Single Page Applications Modify the URL fragments for stateful AJAX pages http://example.com/page?query#!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 http://example.com/page?query&_escaped_fragment_=state Show the original URL to users in the search results
  • 23. She is thinking keywords. Again.
  • 24. A document's relevance given a user query Example: Query “SEO” on Google.es Match keyword Search engine optimization - Wikipedia, the free encyclopedia en.wikipedia.org/wiki/Search_engine_optimization‎ 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 www.seo.org 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. 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. Latent Dirichlet Allocation LDA Source: http://moz.com/blog/lda-and-googles-rankings-well-correlated
  • 27. Topic modelling - LDA LDA based feature selection is reliable and generally better than document frequency based feature selection Source: http://mengjunxie.github.io/ae-lda/index.html
  • 28. Structured data
  • 29. Markup detected by Google Example of the webpage of an event - Structured Data Testing Tool
  • 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. 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
  • 32. Example of structured markup in retail Prominent results at the top of Google SERP Source: groovecommerce.com
  • 33. Other examples of structured data Classifieds, aggregators, online music stores… Source: http://support.google.com
  • 34. Engagement Tools: Google Analytcs and server logs Usage metrics, e.g. conversions (goals), time per page, pages/session, social signals, etc. are now part of SEO. Google Analytics lets you detect losses in the navigation flow of your website
