Many<br \/>\n  <a href=\"https:\/\/support.google.com\/webmasters\/answer\/7576553\" class=\"external-link\">features are available only to site owners<\/a><br \/>\n  and we want as many webmasters as possible to have access. Most site owners who can&#8217;t upload<br \/>\n  files or specify names for files should be able to use this new method to verify. For instance,<br \/>\n  if you use Blogger, you can<br \/>\n  <a href=\"https:\/\/support.google.com\/webmasters\/answer\/9008080\" class=\"external-link\">verify using this option<\/a>.\n<\/p>\n<p>\n  To verify using the <code>&lt;meta&gt;<\/code> tag, simply click the <b>Verify<\/b> link for your site,<br \/>\n  choose <b>Add a <code>meta<\/code> tag<\/b> as the verification option, and then copy the tag provided to the<br \/>\n  <code>&lt;head><\/code> section of your home page.\n<\/p>\n<p>This tag looks like this:<\/p>\n<div><\/div>\n<p>You must place this <code>meta<\/code> tag:<\/p>\n<ul>\n<li>On the home page of your site (sometimes called the index page or root page).<\/li>\n<li>In the source code for that page.<\/li>\n<li>\n    In the first <code>&lt;head><\/code> section of the page, before the first<br \/>\n    <code>&lt;body><\/code> section.\n  <\/li>\n<\/ul>\n<p>You can&#8217;t place this tag inside of another tag in the head section.<\/p>\n<p>For instance, this is correct:<\/p>\n<div><\/div>\n<p>The <code>meta<\/code> tag inside the style section is incorrect:<\/p>\n<div><\/div>\n<p>The <code>meta<\/code> tag inside the body section is incorrect:<\/p>\n<div><\/div>\n<p>The <code>meta<\/code> tag on a page with no head section is incorrect:<\/p>\n<div><\/div>\n<p>Below are some questions you might have about verification.<\/p>\n<h2 id=\"i-have-a-blog,-and-anyone-can-post-comments.-if-they-post-this-meta-tag-in-a-comment,-can-they-can-claim-ownership-of-my-site\" tabindex=\"-1\">\n  I have a blog, and anyone can post comments. If they post this <code>meta<\/code> tag in a comment, can they can<br \/>\n  claim ownership of my site?<br \/>\n<\/h2>\n<p>\n  No. We look for this <code>meta<\/code> tag in the home page of your site, only in the first section and before<br \/>\n  the first. If your home page is editable (for instance, your site is a wiki-like site or a blog<br \/>\n  with comments or has a guest book), someone can add this <code>meta<\/code> tag to the editable section of your<br \/>\n  page, but cannot claim that they own it.\n<\/p>\n<h2 id=\"so,-how-do-you-generate-these-cryptic-tags-anyway\" tabindex=\"-1\">So, how do you generate these cryptic tags anyway?<\/h2>\n<p>\n  The unique string is generated by base-64 encoding the SHA256 hash of a string that is composed of<br \/>\n  the email address of the proposed owner of the site (for instance, admin@example.com) and the<br \/>\n  domain name of the site (for instance, example.com).\n<\/p>\n<h2 id=\"from-this-unique-string,-can-someone-determine-my-email-address-or-identity\" tabindex=\"-1\">From this unique string, can someone determine my email address or identity?<\/h2>\n<p>\n  Short answer, no. Long answer, we use a hashing scheme to compute the contents of the <code>meta<\/code> tag.<br \/>\n  Hashes cannot be &#8220;decrypted&#8221; back into the message.\n<\/p>\n<h2 id=\"can-the-meta-tag-contents-be-cracked-through-a-dictionary-attack\" tabindex=\"-1\">Can the <code>meta<\/code> tag contents be cracked through a dictionary attack?<\/h2>\n<p>\n  To reduce the risk of dictionary attacks, we use a random sequence of bytes (called salt) as a<br \/>\n  seed to the hash function. This makes dictionary attacks much more difficult.\n<\/p>\n<h2 id=\"can-someone-determine-if-the-same-webmaster-own-multiple-sites\" tabindex=\"-1\">Can someone determine if the same webmaster own multiple sites?<\/h2>\n<p>\n  We use the domain name of your site (for instance, example.com ) to compute the unique string.<br \/>\n  Based on the contents of the tag, someone can determine if a webmaster owns different sites on the<br \/>\n  same domain, but not if the webmaster owns sites on different domains. For instance, someone can<br \/>\n  determine if the same webmaster owns https:\/\/www.example.com\/ and https:\/\/subdomain.example.com\/,<br \/>\n  but can&#8217;t determine if the same webmaster owns https:\/\/www.example.com\/ and<br \/>\n  https:\/\/www.google.com\/.\n<\/p>\n<h2 id=\"what-if-my-home-page-is-not-html-content\" tabindex=\"-1\">What if my home page is not HTML content?<\/h2>\n<p>\n  This method may not work for you. You must have a <code>&lt;head><\/code> section in order to be<br \/>\n  able to verify using this approach. Instead, try uploading a verification file to verify<br \/>\n  ownership of your site.\n<\/p>\n<h2 id=\"ive-added-my-tag,-but-google-sitemaps-says-it-couldnt-find-it.-why\" tabindex=\"-1\">I&#8217;ve added my tag, but Google Sitemaps says it couldn&#8217;t find it. Why?<\/h2>\n<p>\n  Make sure your tag is in the first <code>&lt;head><\/code> section, and before the<br \/>\n  <code>&lt;body><\/code> section. Also ensure that it&#8217;s not within the <code>&lt;style><\/code> tags<br \/>\n  or other specialized tags. The easiest way to make sure that the placement is one we can recognize<br \/>\n  is placing it right after your opening &lt;head> tag, as follows:\n<\/p>\n<div><\/div>\n<p class=\"byline-author\">Posted by <a href=\"https:\/\/www.vanessafox.com\/\" class=\"external-link\">Vanessa Fox<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>It&#8217;s been a while since we published this blog post.
