How Many Keywords Can I SEO Per Web Page? | SEO White Hats
Written by JoSEO Best Practices often refer to the rule of optimizing for “One Keyword Phrase Per Page” and this is very good advice. This rule first applies to the most important on-page ranking factor - the of the page. If you are optimizing for “Valentines Gifts”, your page title should start with <TITLE>Valentines Gifts - Cupids Shop” or even better would be Valentines Gifts - Best Gifts for Valentines Day - Cupids Shop.
This second title is optimized for both ‘Valentines Gifts’ as well as ‘Gifts for Valentines’. With our available space of 65 characters, this title is also optimized for ‘Best Valentines Gifts’, ‘Valentines Day Gifts’, and the long tail of ‘Best Valentines Day Gifts’. Some people would argue that this page is now attempting to optimize for more than one keyword phrase. Our strategy, in this example, is to primarily optimize for ‘Valentines Gifts’ and then to find the best keyword phrases to use for our variations.
