  • 1. URL Parameters in Webmaster ToolsMaile OhyeDeveloper Programs Tech LeadGoogle
  • 2. URL Parameters in Webmaster Tools
  • 3. Advanced featureSome sites already have high crawl coverageas determined by Google.Improper actions can result in pages notappearing in search.
  • 4. URL Parameters hint (vs. directive)● URL parameters can be helpful hint● robots.txt or meta noindex is more a directive than hint
  • 5. Issue: Inefficient crawlingwww.googlestore.com● 158 products● 380,000 URLs identified by Googlebot!
  • 6. Issue: Crawling redundant orduplicative content/itemshttp://www.googlestore.com/googlesearch.aspx?category=You%20Tubehttp://www.googlestore.com/googlesearch.aspx?category=You%20Tube&size=M
  • 7. Assists understanding parametersto crawl site more efficiently● Crawl your site more efficiently (decrease number of duplicates) ○ Saves bandwidth ○ Helps more unique, fresh content to be indexed● For removals, go to URL Removals in Webmaster Tools
  • 8. On-page markup can still be applied Page-level markup ● rel="canonical" ● rel="prev" and rel="next" ● rel="alternate" hreflang="x" ● noindex is still taken into consideration if page is crawled. * Make sure we can crawl your page (i.e., not robots.txt disallowed), if you want page-level markup applied!
  • 9. URLs eligible for the featurehttp://www.googlestore.com/googlesearch.aspx?category=officehttp://www.googlestore.com/googlesearch.aspx?category=Wearableshttp://www.googlestore.com/googlesearch.aspx?category=Wearables&size=M
  • 10. http://www.example.com/page.php?key=value&key2=value2 which we interpret as equivalent to http://www.example.com/page.php?key2=value2&key=value
  • 11. Ineligible URLshttp://www.example.com/Wearables++Youtube++size+M.axdhttp://example.com/hotels/cancun/a7a141343.htmlhttp://example.com/cancun+hotel+zone-hotels-1-23-a7a141343.html
  • 12. Step 1: Specify parameters that do notchange content1. Do I have parameters that dont affect the page content (e.g., SID, affiliateID, or tracking-id)? Likely mark as "does not change content." ● Results as "One representative URL" setting in Webmaster Tools
  • 13. Step 2a: Specify parameters that changecontent
  • 14. Step 2b: Specify Googlebots preferredbehavior
  • 15. Sort parameterChanges the order content is presented● sort=price_ascending● rankBy=bestSelling● order=highest-rated● sort=newest Example of sort parameter pulldown menu
  • 16. 1. Identify the sort parameter2. Specify Googlebots preferred behavior forURLs with this parameter
  • 17. Option 1: Sort parameter neverdisplayed by default?1. Is the sort parameter optional throughout my entire site (i.e. not displayed by default, but only with manual selection)?2. Can Googlebot discover everything useful when the sort parameter isnt displayed?If "yes," likely that with your parameter you canspecify "crawl No URLs."Verify examples displayed arent canonical, andthat the canonical can be reached withJavaScript turned off during navigation.
  • 18. Option 2: Same sort values site-wide?1. Are the same sort values used consistently across my entire site? (e.g., not sort=year- issued as a sort option for selling coins but not coin albums)2. When a user changes the sort value is the total number of items unchanged? If "yes," likely that with your sort parameter you can specify "only URLs with value x" where x is one of the sorting values used site-wide.
  • 19. Option 3: Let Googlebot decideIf neither rule applies "Let Googlebotdecide."
  • 20. NarrowsFilters the content on the page by showingsubset of total items. size=M less_than=25 color=blue Example of "narrows" on an e-commerce site
  • 21. Narrows● If the "narrows" parameter shows less useful content thats a subset of the content from the more useful URL without the "narrows" parameter, you might be able to specify "Crawl No URLs."Useful: category=You%20TubeLess useful: category=You%20Tube&size=M ○ But verify a few things first...
  • 22. Narrows and "Crawl No URLs"1. Be sure the "narrows" parameter wont also filter out useful pages youd like crawled and surfaced in search results (e.g., perhaps brand or category pages)2. Verify that the example URLs shown in the Webmaster Tools provide non-searcher useful content when compared to the parent URL
  • 23. Narrows (cont.) If "Crawl No URLs" isnt optimal for your site, then perhaps select "Let Googlebot decide."
  • 24. SpecifiesDetermines the content displayed on a page.● itemid=android-t-shirt● SKU=495Crawl every URL.
  • 25. TranslatesUnless you want to exclude certain languagesfrom being crawled/available in search results,(e.g., auto-generated translations), select"Crawl every URL."
  • 26. Translates (cont.) Best practice to place languages in subdirectory or subfolder rather than parameter to help search engines more easily understand site structure.
  • 27. PaginatesDisplays one component page of a multi-page sequence.● page=3● viewItems=10-30● start-index=20Nearly always "Crawl every URL."
  • 28. Multiple parameters in one URLexample.com/item.php?sku=234&page=3&sortBy=price&sortOrder=lowToHigh Imagine all URLs begin as eligible for crawling, then apply each setting as a process of elimination, not inclusion.
  • 29. RecapUtilize URL Parameters for more efficientcrawling ○ Specify parameters that do not change content ○ Specify parameters that change content ■ If you cant determine, dont guess, "let Googlebot decide"
  • 30. Recap (cont.)● Sorts ○ If parameter never exists in URL by default: "Crawl no URLs" ○If parameter values are used consistently site-wide: "Crawl URLs with value x"● Narrows: for non-useful filters "Crawl no URLs" (but be sure to double-check :)● Specifies: usually "Crawl every URL"● Translates: usually "Crawl every URL"● Paginates: usually "Crawl every URL"
