  22. Competitiveness • Competition for that keyword should also be considered • Calculate KEI Score (Keyword Effectiveness Indicator) = ratio of searches over number of pages in search results. • The higher the KEI Score, the more attractive the keyword is to target (assuming it’s relevant to your business). • Perform advanced searches to determine difficulty • “digital cameras” • intitle:“digital cameras”

  23. Duplicate Content

  24. Syndicating Exact Copies = BAD NYTimes.com Syndicate-NYTimes.com

  25. What if your search results looked like this?

  26. How Search Engines Prevent It • Identify Duplicate Content • Pick One as a Winner • Ignore the Rest • Helps prevent poor quality search experiences such as that shown on the prior slide

  27. Picking the Winner • Where Google first saw the content • Trust in the domain • Best link graph • Do copies link back to the original? • Does it look like it was scraped? • Only if it’s close, PageRank

  28. Detecting Duplicate Content • Navigation / Templates ignored • Simple Text comparisons • Shingles (will illustrate in a moment) • Factor out word substitution • Content does not have to match exactly to be duplicate • What % makes a duplicate? • Not published by search engines, changes over time

  29. Word Substitution • Our San Diego pizzas are the finest available. We provide high quality San Diego pizzas to … • Our San Jose pizzas are the finest available. We provide high quality San Jose pizzas to … • This is still duplicate content!

  31. This is the Same Page!

  32. Text Based Example The clueless fool decided to make the best of it by going to find … However, he kept bumping his head into the door, which led to a severe lowering of his already limited intellect …

  33. And this is the Same Content! However, he kept bumping his head into the door, which led to a severe lowering of his already limited intellect … The clueless fool decided to make the best of it by going to find …

  34. How Dupe Content is Created • Faceted Navigation (sort by price, sort by color …) • Session IDs on URLs ?id=890889089 • Different URLs resolving to the same content: • http://www.domain.com/content17 • http://domain.com/content17 • https://www.domain.com/content17 • Affiliate programs: • http://www.domain.com/content17?afid=stone • Syndicating content

  35. Costs of Duplicate Content • Wasted Crawl Budget • Search engines limit how much they will crawl a site during a given day • Time spent crawling dupes is wasted • Valuable (non-dupe) pages may not get crawled • Wasted PageRank / link juice • Links to dupes provide no value

  36. Solutions • In priority order: • Simply eliminate it • 301 redirect un-needed copies to preferred version • Canonical tag • <link rel="canonical" href="http://www.example.com/product.php?item=swedish-fish" /> • Use robots.txt to prevent crawling of the dupes • If syndicating content • Syndicate content not published on your site • Differentiate content via added content (e.g. UGC) • Include a link back to the original article

  37. Watch for “Pseudo-Dupes” • This is content on your site which competes for the same keywords • Once again, the search engines will pick one, and ignore the others!

  38. Duplicate Title Tags • Check for duplication • Use special queries with Google to find duplication. • Over 9,000 duplicates of this title alone … what does it say to Google? • Purely duplicate titles • Canonicalization • Parameters & URL bloat • Site:domain.comintitle:”title”

  39. Google Helps Find Duplication • Google’s Webmaster Central • Alerted to duplicate titles
