Since 2009 it is Google's official statement that they don't use the meta keywords tag for ranking purposes: https://webmasters.googleblog.com/2009/09/google-does-not-use-keywords-meta-tag.html
They in fact even that they sometimes use it as a spam signal, especially for webmasters that enter a great number of keywords in it.
In terms of inserting keywords ...
FYI, meta tags have no effects on rankings so no meta tags is the same as empty meta tags is the same as full meta tags.
Having said that, empty meta tags are the same as no meta tags. Either way you are not providing search engines or any other crawler any information normally provided in those tags. If I had to choose one or the other I would simply omit ...
There is no benefit in using the hreflang on a single language website, it is meant exclusively for multilingual and international websites. I am not suggesting that Google (or other search engines) would penalize you for it, but they would definitely not reward you.
You can see a proper implementation of the hreflang tag over at trip advisor - a well ...
Do not remove this. Someone has put it there for a purpose.
Its useful because people (often unknowingly) install the Skype toolbar, which horribly throws out the design of a website in many instances.
I add that code to all of the websites I build, because you just get complaints or problems somewhere down the track.
As of today's date, this solution ...
2020 Update from @MattGreer:
It seems like now the image needs to be 1200x630, and not 2:1 anymore.
Once I used that size, my image started showing up. See @johanv's
Original answer from 2015:
There appear to be 2 key considerations which need to be taken care of before the image will display for the [summary_large_image] twitter card:
The image ...
It depends on the definition of abstract.
For HTML5, abstract is not registered. So you must not use this metadata name in (X)HTML5 documents. The metadata name description is defined in the HTML5 specification itself, so it’s valid to use it in (X)HTML5 documents.
In HTML 4.01, you can use any metadata names, so using abstract would be allowed. But it ...
For my paginated results, what I did was dynamically add page numbers and a result index. For example:
<meta name="description" content="Page 3 of 11, nike shoes 30 to 40 out of 300.
Buy good quality nike shoes blah blah">
In the above example, page 3 of 11 and pages 30 to 40 out of 300 would dynamically be generated using PHP or similar. This is OK ...
For HTML5, there is no title metadata name. You may only use values defined in the HTML5 spec or registered in the WHATWG wiki, and as title is not registered, you can’t have an element like:
<meta name="title" content="…"> <!-- invalid in HTML5 -->
In HTML 4.01, you may use any value (there is no registry):
<meta name="title" content="…"&...
In HTML5, keywords is one of the standard metadata names.
It defines steps that user agents must follow to obtain the page’s list of keywords. One of these steps is:
Split the value of the element's content attribute on commas.
As the linked definition of "split a string on commas" explains, "leading and trailing whitespace" will be stripped:
Yes, <meta name="title" ../> is superfluous.
It is clear, after reading the HTML specification of the meta tag:
The meta element represents various kinds of metadata that cannot be
expressed using the title, base, link, style, and script elements.
So the meta title doesn't provide any additional information to the title tag, and it is not even ...
While for the purposes of SEO, it may be true that the order is not significant, it is not true when considering other things like security, content (character) display, or loading speed. It is a good idea to order your page’s head roughly thus (presuming HTML5 for syntax):
So far in the document, you should not have used any non-ASCII ...
There are no tangible benefits from using the hreflang attribute, beyond special usage like the one described by Google. It is declarative markup and does not cause any action or affect rendering, unless you make it to. The HTML5 LC explicitly warns: “It is purely advisory. [...] User agents must not consider this attribute authoritative — upon fetching the ...
No, you do not need an alt attribute on that meta tag. In fact, it is not even allowed as others have already said.
However, (today) Open Graph specifies and even suggests to provide the image alt text via an og:image:alt property. See http://ogp.me/#structured.
Note that the og:image meta tag is not an image tag, but rather a hint on which image should be ...
Search engines crawlers follow the most restrictive rule. If you use nofollow in your meta tag, no link will be followed. If you use follow in your meta tag, all links will be followed except those with rel="nofollow".
So answer to your question is no, meta tag with follow doesn't override individual rel="nofollow".

New sites often do drop in rank
Sadly, the chances are that Google is repositioning to where it believes you should be. Most often, new sites and pages get temporary boosts to allow them to catch on, so to speak. I've seen what you're experiencing hundreds of times and can assure you what you're seeing is most likely out of your control until your site ...
<meta property="article:tag" content="Article Tag" /> is one of the Facebook Open Graph tags. Having social media metadata in the website is one of the best practice as it will tell how our webpage's Title, URL, Image, Description, site_name etc should display while sharing.
But I don't think <meta property="article:tag" content="Article Tag" /> ...
Meta Description = Search Engines, OG Descriptions = Social Platforms
Meta Description is used by Search Engines Bots, while the OG (The Open Graph protocol) is used by Social Media Bots, therefore if you want 'extra' information on Social Media sites then you should opt to use both the META and OG tags. You can find a list of whom uses OG below.
After verifying site ownership, is it ok to remove the <meta name="google-site-verification"> tag?
No. If you want to remove it and remain verified, you'll need to use another form of verification.
There is no benefit to having an empty meta description or meta keywords. They take up a few bytes in the page source. You might as well leave them out.
On the flip side, it shouldn't really hurt when those fields are empty compared to not having them. If your CMS requires that they are there and you don't want to write content for them, it would be OK ...
You have good intentions, but you are using some elements wrong, so let me clarify a few things and the answer to your question will be at the end.
Each page on a site has a language, that means that there is one main language for the content of a given page. That language, should be defined on the right meta tag, specifically, content-language, like this
Your plan of using meta data for microdata is not viable. Here is Google's FAQ about why it isn't showing your data in the search results:
Is your marked-up content hidden from users?
In general, Google won't display any content in rich snippets that is not visible to human user. Don't hide the content that you have marked up for rich snippets ...
Google maintains a list of all the meta tags that it uses. It lists the <title> tag (although it notes that it is technically not a meta tag). It does not list <meta name="title"> tags.
Most websites rank very well without meta tags named "title". I've never used such a tag myself before. Your use of a meta title tag would be ignored by ...
The meta name verify-v1 used to be associated with Google Webmaster Tools, it is now deprecated and has been replaced with the meta name google-site-verification, which now works across Google's services and not just restricted to WMT.

Google usually shows differing search results when people search for the singular vs the plural. So SEO has to be done separately for the different terms.
Start by figuring out which version (singular or plural) has the higher search volume. Use the Adwords Keyword Tool to compare search volumes. Make sure to select "[Exact]" as the "Match Type" in the ...
Character references like З have been part of HTML for a long, long time, and they are frequently used for various reasons. Google is known to support them (as you say), and it would be very odd for it to drop the support. So from the SEO point of view, there is no need to get rid of such references.
The main problem with character references is ...
In my case my image path had an extra forward slash, which worked fine in-browser, but wasn't picked up by Twitter. It was a one character error that was hard to spot.
E.g. check for this:
And change it to this:
