Keyword density is divorced from content, quality, semantics, and relevancy.6 Confidential Global Marketing
  7. 7. On Page Optimization• On-page Optimization – Use the keyword in the title tag at least once and as close to the beginning of the title as possible – Once in the H1 header tag – At least thrice in the body copy of the page – At least once in bold (either <strong> or <b>), in the alt attribute of the images, in the URL and at least once in the meta description tag (Meta description tag does not get used by Search Engines) – Generally not in the link anchor of the page that is linked to other pages• Title Tags – Be mindful of the length. 70 characters is the maximum that will be displayed in search results – Place important keywords close to the front. – Leverage Branding – Consider readability and emotional impact  first interaction of the user with the brand• Meta Tags – Meta Robots  Index/No Index, Follow/No Follow, Noarchive, Nosnippet, NoODP, NoYDir – Meta Description  Primary source for snippets displayed; Engines do not use keywords in this tag for ranking – Meta Keywords  No longer important for SEO – Some more like meta revisit-after, meta refresh7 Confidential Global Marketing
  8. 8. URLs & Duplicate Content• URL Structures – Shown in Search results & address bar; can impact clickthrough & visibility. More credit is given to the page when the query term is part of the URL. – Can influence the link anchor text for outbound links• URL Construction Guidelines – URL should provide good idea about the content on the page – Shorter is better – Keyword use is important but don’t overuse – Use static URLs. Every single dynamic parameters in the URL can result in lower overall ranking – Be descriptive (don’t use meaningless numbers/texts) and use hyphens to separate words• Canonical and Duplicate Versions of Content – Organize the content - only one URL for every unique piece of content  singular version of the content and Search engine can assign it the highest achievable rankings – Use 301 re-direct or “Canonical URL Tag” <link rel="canonical" href="" /> – Scraping  Practice of fetching one’s content and re-publishing; Make use of Ping services and use absolute links instead of relative links in the page8 Confidential Global Marketing
