Does google look at H3 tags?
-
I've had someone tell me that google doesn't pay attention to H3 tags -- only H1 and H2. I haven't found much online to back this up or discredit it; thought I'd ask the Moz community!

Pay this person no mind in the future.
The answer given by Nicholas White is perfect.

Google does look at h tags to understand the structure of the content on the page better, Googler John Mueller confirmed this several years ago. Therefore it’s good practice to have your H1 as a main page or title of the piece then main subheadings as H2, any further sub-headings needed to divide content under these H3-H6. A lot don’t go to this depth and focus on H1 and multiple H2s achieving good results. When I have taken it further I don’t believe it has made a significant impact on rankings compared to when I haven’t.
Hope this helps -
My understanding is they do look at H3 tags and valuate them as being higher emphasis than normal paragraph copy, however, they do not have a much "weight" in the on-page algorithm as the H1 or H2s. If having H3s makes sense for your page's content and helps the user better read and understand the content, I say H3s are positive and I would not hesitate to use them.

Removing a site from Google index with no index met tags
Hi there! I wanted to remove a duplicated site from the google index. I've read that you can do this by removing the URL from Google Search console and, although I can't find it in Google Search console, Google keeps on showing the site on SERPs. So I wanted to add a "no index" meta tag to the code of the site however I've only found out how to do this for individual pages, can you do the same for a entire site? How can I do it? Thank you for your help in advance! L

Fake Links indexing in google
Hello everyone, I have an interesting situation occurring here, and hoping maybe someone here has seen something of this nature or be able to offer some sort of advice. So, we recently installed a wordpress to a subdomain for our business and have been blogging through it. We added the google webmaster tools meta tag and I've noticed an increase in 404 links. I brought this up to or server admin, and he verified that there were a lot of ip's pinging our server looking for these links that don't exist. We've combed through our server files and nothing seems to be compromised. Today, we noticed that when you do site:ourdomain.com into google the subdomain with wordpress shows hundreds of these fake links, that when you visit them, return a 404 page. Just curious if anyone has seen anything like this, what it may be, how we can stop it, could it negatively impact us in anyway? Should we even worry about it? Here's the link to the google results. https://www.google.com/search?q=site%3Amshowells.com&oq=site%3A&aqs=chrome.0.69i59j69i57j69i58.1905j0j1&sourceid=chrome&es_sm=91&ie=UTF-8 (odd links show up on pages 2-3+)

Is Google suppressing a page from results - if so why?
UPDATE: It seems the issue was that pages were accessible via multiple URLs (i.e. with and without trailing slash, with and without .aspx extension). Once this issue was resolved, pages started ranking again. Our website used to rank well for a keyword (top 5), though this was over a year ago now. Since then the page no longer ranks at all, but sub pages of that page rank around 40th-60th. I searched for our site and the term on Google (i.e. 'Keyword site:MySite.com') and increased the number of results to 100, again the page isn't in the results. However when I just search for our site (site:MySite.com) then the page is there, appearing higher up the results than the sub pages. I thought this may be down to keyword stuffing; there were around 20-30 instances of the keyword on the page, however roughly the same quantity of keywords were on each sub pages as well. I've now removed some of the excess keywords from all sections as it was getting in the way of usability as well, but I just wanted some thoughts on whether this is a likely cause or if there is something else I should be worried about.

Pages removed from Google index?
Hi All, I had around 2,300 pages in the google index until a week ago. The index removed a load and left me with 152 submitted, 152 indexed? I have just re-submitted my sitemap and will wait to see what happens. Any idea why it has done this? I have seen a drop in my rankings since. Thanks

CDN Being Crawled and Indexed by Google
I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases. It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt? Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL. Thanks! Scott

How do I fix the h1 tag?
No More Than One H1 Tag Easy fix <dl> <dt>Number of H1s</dt> <dd>2</dd> <dt>Explanation</dt> <dd>Best practices for both SEO and accessibility require only a single H1 tag. The H1 is meant to be the page's headline, and thus, multiple H1s are confusing. Consider employing H2, H3 or CSS styles to achieve the same results with text visualization.</dd> <dt>Recommendation</dt> <dd>Remove multiple instances of the H1 tag, so that only one exists on the page.</dd> <dd>I get this error yet it does not tell me how to fix it. I'm not even sure what the H1 tag is?
