You missed title in  lt a gt  element     lt h1 id  logo  gt     lt a href     title       gt  lt span gt Stack Overflow lt  span gt  lt  a gt   lt  h1 gt    I suggest to put title in  lt a gt  element because client would want to know what is the meaning of that image  Because you have set text-indent for the test of  lt h1 gt  so  that front end user could get information of main logo while they hover on logo

lt h1 gt     lt a href  http   stackoverflow com  gt    Stack Overflow lt img src  logo png  alt  Stack Overflow    gt     lt  a gt   lt  h1 gt    This was the good option for SEO because SEO gives the H1 tag high priority  inside the h1 tag should be your site name  Using this method if you search the site name in SEO it will show your site logo as well   you want to hide the site name OR text please use text-indent in negative value  ex  h1 a    text-indent  -99999px

I think you d be interested in the H1 debate  It s a debate about whether to use the h1 element for the page s title or for the logo    Personally I d go with your first suggestion  something along these lines    lt div id  header  gt       lt a href  http   example com   gt  lt img src  images logo png  id  site-logo  alt  MyCorp    gt  lt  a gt   lt  div gt    lt  -- or alternatively  with css in a stylesheet ofc-- gt   lt div id  header  gt       lt div id  logo  style  background  url  logo png    display  block           float  left  width  100px  height  50px   gt           lt a href     style  display  block  height  50px  width  100px   gt               lt span style  visibility  hidden   gt Homepage lt  span gt           lt  a gt       lt  div gt       lt  -- with css in a stylesheet  -- gt       lt div id  logo  gt  lt a href     gt  lt span gt Homepage lt  span gt  lt  a gt  lt  div gt   lt  div gt     lt div id  body  gt       lt h1 gt About Us lt  h1 gt       lt p gt MyCorp has been dealing in narcotics for over nine-thousand years    lt  p gt   lt  div gt    Of course this depends on whether your design uses page titles but this is my stance on this issue

If accessibility reasons is important then use the first variant  when customer want to see image without styles    lt div id  logo  gt       lt a href    gt           lt img src  logo png  alt  Stack Overflow    gt       lt  a gt   lt  div gt    No need to conform imaginary SEO requirements  because the HTML code above has correct structure and only you should decide does this suitable for you visitors    Also you can use the variant with less HTML code   lt h1 id  logo  gt     lt a href    gt  lt span gt Stack Overflow lt  span gt  lt  a gt   lt  h1 gt       position code  it may be absolute position or normal - depends on other parts of your site     logo             logo a      display block     width  actual image width     height  actual image height     background  url image png  no-repeat left top        for accessibility reasons - without styles variant    logo a span  display  none    Please note that I have removed all other CSS styles and hacks because they didn t correspond to the task  They may be usefull in particular cases only

One point no one has touched on is the fact that the h1 attribute should be specific to every page and using the site logo will effectively replicate the H1 on every page of the site   I like to use a z index hidden h1 for each page as the best SEO h1 is often not the best for sales or aesthetic value

After reading through the above solutions  I used a CSS Grid solution    Create a div containing the h1 text and the image  Position the two items in the same cell and make them both relatively positioned  Use the old zeldman com technique to hide the text using text-indent  white-space  and overflow properties     lt div class  title-stack  gt       lt h1 class  title-stack  title  gt StackOverflow lt  h1 gt       lt a href     class  title-stack  logo  gt           lt img src   images stack-overflow png  alt  Stack Overflow  gt       lt  a gt   lt  div gt     title-stack       display  grid     title-stack  title   title-stack  logo       grid-area  1 1 1 1      position  relative     title-stack  title       z-index  0      text-indent  100       white-space  nowrap      overflow  hidden

I do it mostly like the one above  but for accessibility reasons  I need to support the possibility of images being disabled in the browser  So  rather than indent the text from the link off the page  I cover it by absolutely positioning the  lt span gt  to the full width and height of the  lt a gt  and using z-index to place it above the link text in the stacking order   The price is one empty  lt span gt   but I m willing to have it there for something as important as an  lt h1 gt       lt h1 id  logo  gt     lt a href    gt Stack Overflow lt span gt  lt  span gt  lt  a gt   lt  h1 gt     logo a      position relative     display block     width  image width      height  image height       logo a span      display block     position absolute     width 100      height 100      background  ffffff url image png  no-repeat left top     z-index 100     Places  lt span gt  on top of  lt a gt  text

Chiming in a bit late here  but couldn t resist   You re question is half-flawed  Let me explain   The first half of your question  on image replacement  is a valid question  and my opinion is that for a logo  a simple image  an alt attribute  and CSS for its positioning are sufficient   The second half of your question  on the  SEO value  of the H1 for a logo is the wrong approach to deciding on which elements to use for different types of content   A logo isn t a primary heading  or even a heading at all  and using the H1 element to markup the logo on each page of your site will do  slightly  more harm than good for your rankings  Semantically  headings  H1 - H6  are appropriate for  well  just that  headings and subheadings for content    In HTML5  more than one heading is allowed per page  but a logo isn t deserving of one of them  Your logo  which might be a fuzzy green widget and some text is in an image off to the side of the header for a reason - it s sort of a  stamp   not a hierarchical element to structure your content  The first  whether you use more depends on your heading hierarchy  H1 of each page of your site should headline its subject matter  The main primary heading of your index page might be  The Best Source For Fuzzy Green Widgets in NYC   The primary heading on another page might be  Shipping Details for Our Fuzzy Widgets   On another page  it may be  About Bert s Fuzzy Widgets Inc    You get the idea   Side note  As incredible as it sounds  don t look at the source of Google-owned web properties for examples of correct markup  This is a whole post unto itself    To get the most  SEO value  out HTML and its elements  take a look at the HTML5 specs  and make make markup decisions based on  HTML  semantics and value to users before search engines  and you ll have better success with your SEO
