  Amit Sharma: Hello,
  Can anyone please tell me is it good to use more than 1 H1 tag on a page. On my site's homepage there are 5 sliders, can i use H1 tags on all the 5 sliders?

  Federico Sasso: It still would be valid HTML, but keep in mind that H1 are meant to give semantic weight to title/subtitles, and in the eyes of a search engine that weight would be split in five.

  SKI USA INC: There is no limit for using h1 tags a video by Matt Cutts where he explained where and how to use H1 tags. More than one H1 on a page: good or bad?

  Patrick Rabanser: Hy +Amit Sharma ;I looked at your Website and I see u don't use any H1 only H2 Tags for the Slider Buttons, for the titles in the Sliders u use <span>, you should change that and use H Tags!
  
  About the use of H1, I see u use HTML5, with HTML5 you could put one H1 in the Page Header an another in the main Content of your page. I wouldn't use more then that because Users and Search Engines might get confused! ;
  But you should use at least 1 H1 on every single page, remember never to use the same Title multiple times!
  
  +SKI USA INC ;Matt Cutts Video about H1 Tags is 4 years Old, a lot has changed since then, but still good Information!
  He says in the video, use H1 Tags in a logical way! And you should always think logical when u use H Tags. ;
