Serious researchers wanting reliable, structured search are a miniscule fraction of their customer base. How Google organises and sorts information : How Google organises and sorts information Has a primary index of higher "quality" documents and a secondary index. Only the primary index is searched when running straightforward searches. Secondary index comes into play with more complex searches and if a small number of results are found. “Dear Bing, We Have 10,000 Ranking Signals To Your 1,000. Love, Google” http://searchengineland.com/bing-10000-ranking-signals-google-55473 Over 200 hundred “signals” and each may have over 50 variations 22/03/2012 www.rba.co.uk 7 How Google ranks and organises your results : How Google ranks and organises your results 22/03/2012 www.rba.co.uk 8 Google personalizes and tailors your results depending on your location, computer/device, browser, past searches, what you have looked at in the past, your +1s, your Google+ account, what you had for breakfast...and anything else it can find by rummaging around in your Google dashboard To see what's in your dashboard log in to your Google account and go to http://www.google.com/dashboard/ Also see Google personalisation: web history isn’t the only problem http://www.rba.co.uk/wordpress/2012/02/22/google-personalisation-web-history-isnt-the-only-problem/ : What I see on my screen for a search is not what you’ll see on yours. 22/03/2012 www.rba.co.uk 9 Google knows best! : Google knows best! 22/03/2012 www.rba.co.uk 10 Hewish mild Google decided to change my search to Jewish mild without asking Placing a phrase within quote marks – "Hewish mild" – will usually force an exact match Google automatically looks for variations of your search terms For 10 days in February 2011: coots = lions : For 10 days in February 2011: coots = lions 22/03/2012 www.rba.co.uk 11 Google decides that coots are really lions http://www.rba.co.uk/wordpress/2011/02/12/google-decides-that-coots-are-really-lions/ Update on coots vs. lions http://www.rba.co.uk/wordpress/2011/02/21/update-on-coots-vs-lions/ Coots = lions : Coots = lions 22/03/2012 www.rba.co.uk 12 Three search tricks : Three search tricks These three techniques can change what Google (and other search engines) decides to give you and also the order of the results. Repeat important search terms coots coots mating behaviour (found coots) Change the order of your terms mating behaviour coots (found coots) Change one of your search terms coots mating behaviour (found lions) coots courtship behaviour (found coots) coots mating ritual (found coots) 22/03/2012 www.rba.co.uk 13 Excluding pages containing words : Excluding pages containing words Want to exclude pages containing a term? Place a - (minus sign) before the term Use with care as may miss important material Excluding lions from our bizarre coots search coots mating behaviour –lions gave us: 22/03/2012 www.rba.co.uk 14 Slide 15: Coots=lions was an extreme example of how Google can work We think Google was doing the following: - assumed a typing error or was running a mobile/smartphone predictive text algorithm (coots=cats) - ran an automatic variation/synonym search on cats - used a search frequency rule and found that lions mating behaviour was requested more than cats 22/03/2012 www.rba.co.uk 15 Slide 16: Dear Google, stop messing with my search http://www.rba.co.uk/wordpress/2011/11/08/dear-google-stop-messing-with-my-search/ 22/03/2012 www.rba.co.uk 16 Google no longer looks for all of your terms in a page See what Google sees : See what Google sees 22/03/2012 www.rba.co.uk 17 Hover over a result and a "preview" of the page should appear to the right together with a Cached link – this is Google's copy Slide 18: “When you do a multi-term query on Google (even with quoted terms), the algorithm sometimes backs-off from hard ANDing all of the terms together.......it’s clear that people will often write long queries (with anywhere from 5 to 10 terms) for which there are no results. Google will then selectively remove the terms that are the lowest frequency to give you some results (rather than none)....Soft AND is a way to reduce the overall frustration and give the searcher something to examine (and with luck, a chance to reformulate their query).” Dan Russell http://www.rba.co.uk/wordpress/2011/11/08/dear-google-stop-messing-with-my-search/#comments 22/03/2012 www.rba.co.uk 18 Verbatim : Verbatim Forces Google to run an exact match search. Run your search first and then select Verbatim from the left hand menu on your results page Cannot be combined with time options in the side bar Google: Verbatim for exact match search http://www.rba.co.uk/wordpress/2011/11/18/google-verbatim-for-exact-match-search/ 22/03/2012 www.rba.co.uk 19 Google doing its own thing can be good : Google doing its own thing can be good 22/03/2012 www.rba.co.uk 20 Slide 21: Google's new(ish) social network Google Plus (Google+) http://plus.google.com/ Google trying forcing people to create a Google+ profile http://marketingland.com/google-now-forcing-all-new-users-to-create-google-enabled-accounts-3912 Search Plus Your World (SPYW) referred to as Search+ now available in Google.com and is the default.
