How will it effect SEO to have multiple h1 tags on a page?
-
I have a client who recieved this advice from his marketing consultant: "If there are multiple h1 tags on a page, this can confuse Google and it may have a negative impact on the keyword rankings. If you could ask your web developer to go in and remove the h1 tags on the header images that would be helpful. This way it will be easier for Google to index your site and will help your keyword rankings."
How will it effect SEO to have multiple h1 tags on a page?

This was a question that was recently raised by somebody else here on the Q&A and you can see the full discussion here. Although the question is slightly different, the answer is the same: it depends which HTML version you are using. If it's HTML4 or XHTML, only use one h1 per page, but if you are using HTML5 you can have one per section. So you could have one in your
<nav>, on in your, one in each of the
<aside>s on your page and one in your
<footer>.
The reason for this is that for HTML4 search engines look at headings to give the page hierachy - remember they only had
s to separate content areas - but HTML5 uses the new semantic elements like
<header>and <fotter>to work out hierarchy, with headings only affecting hierachy within one of those tags.</fotter></header>
</footer>
</aside>
</nav>

Sorry, but have to disagree a bit as having multiple H1's isn't the issue that most think it is, or once was. One of my own sites has 20 H1 tags (purely by chance as it is a single page design, but it's a long story), and that site ranks top 3 for a number of highly competitive phrases with almost half a billion results.
No, it isn't best practice and I wouldn't advocate doing this, but it isn't a major ranking factor.

Your header images should not have h1 tags in them as well because then every page is going to have the same h1 tag with the same keyword - making it so that your are optimizing against that keyword on all your other pages.

Well said iSTORM! To add using images in H1 tags is not very search engine friendly or natural approach. H1 tags are to be used for text only, so adding images may not work to your advantage.
-
Google looks at h1 tags as clues to what the page's content is about. If you have multiple h1 tags with different keywords then it is difficult for Google to contextualize the page.
Best practice: one h1 tag with the keyword or theme you are trying to optimize for.

Will shortening down the amount of text on my pages affect it's SEO performance?
My website has several pages with a lot of text that becomes pretty boring. I'm looking at shortening down the amount of copy on each page but then within the updated, shortened copy, integrating more target keywords naturally. Will shortening down the current copy have a negative effect on my SEO performance?

Duplicate page titles and hreflang tags
Moz is flagging a lot of pages on our site which have duplicate page titles. 99% of these are international pages which hreflang tags in the sitemap. Do I need to worry about this? I assumed that it wasn't an issue given the use of hreflang. And if that's the case, why is Moz flagging them as an issue? Thanks.

Category page canonical tag
I know this question has been asked a few times on here but I'm looking for very specific advice. Currently when you go to a category, say http://www.bronterose.co.uk/range.html, a canonical tag is added to the head of the page. There are plenty of "variant" pages which carry the same tag, for example: /range.html?p=2

/range.html?p=3
/range.html?dir=asc&order=price
/range.html?dir=asc&limit=all&order=price Is it wise to push the "link juice" for each of these variant pages to the top level page? Or should each variant page have its own unique canonical tag? After reading many blog posts, guides and papers I'm truly confused! Any general guidance or recommendations would be much appreciated. Chris.1 -
Do alt tags count towards on page keyword density?
Hello...I have written a bunch of content for my site using a useful tool called Scribe SEO which recommends keyword density at 5% if I remember correctly. So all my my newly written content is below this level but I am left wondering if by adding alt tags with my chosen keywords I will be considered to be over the limit and cause a red flag? Can anyone clarify this for me please?

Is it ok to use the H1 tag for bullet points?
Our search results page doesn't have a typical H1 tag because adding a true header would take up space unnecessarily. Therefore, we've assigned the h1 tag to be the breadcrumb. As filters are applied, the breadcrumb grows to include these filters. This breadcrumb is coded as bullet points, even though they're not the typical style of bullet points. Here's a screenshot: http://screencast.com/t/AjGC9iAYR3 For example, the breadcrumb: Home >> NYC Social Media Classes >> Adult >> Manhattan is currently coded as: | |
On-Page Optimization | | mevseo
| | * class="first"><a <span="">href</a><a <span="">="</a>/">Home |
| | * <a <span="">href</a><a <span="">="</a>/nyc/classes/social-media/age-adults/neighborhood-manhattan" class="Selected">Search results |
| | |
| | |
| | id="cat_social-media" type="checkbox" checked onclick="setCategory('social-media')" /> |
| | # style="font-size: 12px; display: inline;">NYC Social Media Classes |
| | <label <span="">for</label>="cat_social-media"> |
| | |
| | |
| | |
| | <nobr>id="age_adults" type="checkbox" checked onclick="setAge('adults')" /><label <span="">for</label>="age_adults">Adults</nobr> |
| | |
| | |
| | <nobr>id="nbhd_manhattan" type="checkbox" checked onclick="setNeighborhood('manhattan')" /><label <span="">for</label>="nbhd_manhattan">Manhattan</nobr> |
| | |
| | | Right now that H1 tag just relates to 'NYC Social media classes', but we'd like to expand it to include both 'Manhattan' & 'Adults' - would that be ok? And if so, would it be better to put the tag before and after the tag?0 -
Sequence of heading tags (H1, H2, H3, etc) important?
Meaning heading tags (H1, H2, H3, etc) are a critical part of good on-page optimisation. Fair enough. It helps humans and bots make sense of a page's content. 3 questions regarding implementation of heading tags: Should heading tags appear in sequence in the HTML code. I.e. H1 first, then H2 lower down, etc.? Can the page contain more than one H1 tag? Can the page contain multiple H2, H3, H4 tags?
