Does Google ever use the "keywords" meta tag in its web search ranking?

3rd November 2015
Recently we received some questions about how Google uses (or more accurately, doesn't use) the "keywords" meta tag in ranking web search results. Suppose you have two website owners, Alice and Bob. Alice runs a company called AliceCo and Bob runs BobCo. One day while looking at Bob's site, Alice notices that Bob has copied some of the words that she uses in her "keywords" meta tag. Even more interesting, Bob has added the words "AliceCo" to his "keywords" meta tag. Should Alice be concerned?
 
At least for Google's web search results currently (September 2009), the answer is no. Google doesn't use the "keywords" meta tag in our web search ranking. This video explains more, or see the questions below.
Q: Does Google ever use the "keywords" meta tag in its web search ranking?
A: In a word, no. Google does sell a Google Search Appliance, and that product has the ability to match meta tags, which could include the keywords meta tag. But that's an enterprise search appliance that is completely separate from our main web search. Our web search (the well-known search at Google.com that hundreds of millions of people use each day) disregards keyword metatags completely. They simply don't have any effect in our search ranking at present.
 
Q: Why doesn't Google use the keywords meta tag?
A: About a decade ago, search engines judged pages only on the content of web pages, not any so-called "off-page" factors such as the links pointing to a web page. In those days, keyword meta tags quickly became an area where someone could stuff often-irrelevant keywords without typical visitors ever seeing those keywords. Because the keywords meta tag was so often abused, many years ago Google began disregarding the keywords meta tag.
 
Q: Does this mean that Google ignores all meta tags?
A: No, Google does support several other meta tags. This meta tags page documents more info on several meta tags that we do use. For example, we do sometimes use the "description" meta tag as the text for our search results snippets, as this screenshot shows:
 
 
Even though we sometimes use the description meta tag for the snippets we show, we still don't use the description meta tag in our ranking.
 
Q: Does this mean that Google will always ignore the keywords meta tag?
A: It's possible that Google could use this information in the future, but it's unlikely. Google has ignored the keywords meta tag for years and currently we see no need to change that policy.

Meta tags that Google understands

3rd November 2015

Meta tags are a great way for webmasters to provide search engines with information about their sites. Meta tags can be used to provide information to all sorts of clients, and each system processes only the meta tags they understand and ignores the rest. Meta tags are added to the <head> section of your HTML page and generally look like this:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="Description" CONTENT="Author: A.N. Author, Illustrator: P. Picture, Category: Books, Price:  £9.24, Length: 784 pages">
    <meta name="google-site-verification" content="+nxGUDJ4QpAZ5l9Bsjdi102tLVC21AIh5d1Nl23908vVuFHs34="/>
    <title>Example Books - high-quality used books for children</title>
    <meta name="robots" content="noindex,nofollow">

Google understands the following meta tags (and related items):

<meta name="description" content="A description of the page" /> This tag provides a short description of the page. In some situations this description is used as a part of the snippet shown in the search results.More information
<title>The Title of the Page</title> While technically not a meta tag, this tag is often used together with the "description". The contents of this tag are generally shown as the title in search results (and of course in the user's browser). More information
<meta name="robots" content="..., ..." />
<meta name="googlebot" content="..., ..." />
These meta tags can control the behavior of search engine crawling and indexing. The robots meta tag applies to all search engines, while the "googlebot" meta tag is specific to Google. The default values are "index, follow" (the same as "all") and do not need to be specified. We understand the following values (when specifying multiple values, separate them with a comma):
  • noindex: prevents the page from being indexed
  • nofollow: prevents the Googlebot from following links from this page
  • nosnippet: prevents a snippet from being shown in the search results
  • noodp: prevents the alternative description from the ODP/DMOZ from being used
  • noarchive: prevents Google from showing the Cached link for a page.
  • unavailable_after:[date]: lets you specify the exact time and date you want to stop crawling and indexing of this page
  • noimageindex: lets you specify that you do not want your page to appear as the referring page for an image that appears in Google search results.
  • none: is equivalent to noindex, nofollow.

You can now also specify this information in the header of your pages using the "X-Robots-Tag" HTTP header directive. This is particularly useful if you wish to limit indexing of non-HTML files like graphics or other kinds of documents. More information about robots meta tags

<meta name="google" content="nositelinkssearchbox" /> When users search for your site, Google Search results sometimes display a search box specific to your site, along with other direct links to your site. This meta tag tells Google not to show the sitelinks search box. Learn more about sitelinks search box.
<meta name="google" content="notranslate" /> When we recognize that the contents of a page are not in the language that the user is likely to want to read, we often provide a link to a translation in the search results. In general, this gives you the chance to provide your unique and compelling content to a much larger group of users. However, there may be situations where this is not desired. This meta tag tells Google that you don't want us to provide a translation for this page.
<meta name="google-site-verification" content="..." /> You can use this tag on the top-level page of your site to verify ownership for Search Console. Please note that while the values of the "name" and "content" attributes must match exactly what is provided to you (including upper and lower case), it doesn't matter if you change the tag from XHTML to HTML or if the format of the tag matches the format of your page. More information
<meta http-equiv="Content-Type" content="...; charset=..." />
<meta charset="..." >
This defines the page's content type and character set. Make sure that you surround the value of the content attribute with quotes - otherwise the charset attribute may be interpreted incorrectly. We recommend using Unicode/UTF-8 where possible. More information
<meta http-equiv="refresh" content="...;url=..." /> This meta tag sends the user to a new URL after a certain amount of time, and is sometimes used as a simple form of redirection. However, it is not supported by all browsers and can be confusing to the user. The W3Crecommends that this tag not be used. We recommend using a server-side 301 redirect instead.

Other points to note:

  • Google can read both HTML and XHTML-style meta tags, regardless of the code used on the page.
  • With the exception of verify, case is generally not important in meta tags.

This is not an exclusive list of available meta tags, and you should feel free to use unlisted meta tags if they are important to your site. Just remember that Google will ignore meta tags it doesn't know.

Το νέο, επιθετικό Ransomware για Android #LockerPIN διαδίδεται στη Βόρεια Αμερική

19th October 2015

Ερευνητές της ESET ανακάλυψαν το πρώτο «in the wild» ransomware για Android που ρυθμίζει το PIN.

«Με βάση τα στατιστικά στοιχεία του ESET LiveGrid®, η πλειοψηφία των μολυσμένων συσκευών Android εντοπίζεται στις ΗΠΑ με ένα συνολικό ποσοστό άνω του 75%», υποστηρίζει ο Detection Engineer της ESET, Lukáš Štefanko. «Αυτό είναι ενδεικτικό μιας τάσης κατά την οποία οι δημιουργοί του κακόβουλου λογισμικού για Android μετατοπίζουν τις επιθέσεις από κυρίως Ρώσους και Ουκρανούς χρήστες σε Αμερικανούς, για να αποκομίζουν πολύ υψηλότερα κέρδη.»

Το LockerPIN εξαπλώνεται μέσω μη πιστοποιημένων app store που ανήκουν σε τρίτους, φόρουμ warez και torrent. Αφού εγκατασταθεί, ο δούρειος ίππος προσπαθεί να αποκτήσει δικαιώματα διαχειριστή συσκευής εμφανίζοντας πάνω από το μήνυμα του συστήματος ένα δικό του παράθυρο που γράφει «Update patch installation».

Στην παρούσα φάση, ακόμα και αν το trojan αφαιρεθεί, για τις unrooted συσκευές που δεν προστατεύονται από μια λύση ασφάλειας, δεν υπάρχει απλός τρόπος για να αλλαχθεί το PIN εκτός από την επαναφορά των εργοστασιακών ρυθμίσεων. Αυτό όμως οδηγεί σε απώλεια όλων των δεδομένων. Σαν να μην έφτανε αυτό, ακόμη και αν ο χρήστης αποφασίσει να πληρώσει τα λύτρα, οι επιτιθέμενοι δεν μπορούν να ξεκλειδώσουν τη συσκευή, αφού το PIN έχει οριστεί τυχαία.

Για την προστασία από το κακόβουλο αυτό λογισμικό, η ESET συστήνει ως απαραίτητη τη χρήση μιας λύσης ασφάλειας για την περιήγηση στο Διαδίκτυο, όπως το ESET Mobile Security, που έχει σχεδιαστεί ειδικά για Android smartphone και tablet, τη δημιουργία αντιγράφων ασφαλείας τακτικά, και το download εφαρμογών μόνο από πιστοποιημένα app store, όπως το Google Play ή το Amazon App Store.

«Μπορείτε να γλιτώνετε κάποια χρήματα όταν κατεβάζετε εφαρμογές από μη πιστοποιημένες πηγές, αλλά πάντα να έχετε κατά νου, ότι αυτό μπορεί να οδηγήσει σε απώλεια δεδομένων ή προσωπικών στοιχείων, που συνήθως έχουν πολύ μεγαλύτερη συναισθηματική ή οικονομική αξία» προσθέτει ο Štefanko.
