Taking the time to write a good meta description is like sending someone a handwritten thank-you note. It’s not widely done, but it’s a nice touch that can make you stand out. Unlike sending that thank-you note, however, you shouldn’t consider writing your description optional. Given its importance to your website being found (if not its SEO), ignoring this would be a huge mistake. How do you write a good meta description, though? Our guide will walk you through the steps.

Marketing Skills: Writing a Good Meta Description
Meta Description Basics
Taking the time to write a good meta description is like sending someone a handwritten thank-you note. It’s not widely done, but it’s a nice touch that can make you stand out. Unlike sending that thank-you note, however, you shouldn’t consider writing your description optional. Given its importance to your website being found (if not its SEO), ignoring this would be a huge mistake. How do you write a good meta description, though? Our guide will walk you through the steps.Know What Their Purpose Is
Meta descriptions do not actually factor into Google’s search algorithm. What they do, however, is compel people to click on your content—particularly if you use a keyword in the meta description that matches the one they’re searching for. It’s a good place for keywords used strategically (i.e. keywords that aren’t jammed together in a nonsensical stew of words). In addition to appearing on Google, the meta descriptions will also appear when you share a link to your content on Facebook and Google+.
Think Calls-to-Action
Meta descriptions should contain their own kinds of calls-to-action. Just like your actual CTAs should invite people to your landing pages, the meta description should encourage your readers to click on the link and read your content. Things like “Learn the secrets of great inbound marketing,” or “Discover the top trends in blogging for 2013.” It’s not enough to describe the content inside. That, by itself, might not be compelling enough. You have to motivate your readers to want to click and read.
This can be done in more subtle ways than using commands like those listed above. For an example, take a look at the following meta description:
salam every one, this is a topic from google web master centrale blog: Webmaster level: Beginner
Like any curious netizen, I have a Google Alert set up to email me whenever my name is mentioned online. Usually I get a slow trickle of my forum posts, blog posts, and tweets. But by far the most popular topic of these alerts over the past couple years has been my off-handed mention that we removed PageRank distribution data from Webmaster Tools in one of our 2009 releases.
The fact that people are still writing about this almost two years later—usually in the context of “Startling news from Susan Moskwa: ...”—really drives home how much PageRank has become a go-to statistic for some webmasters. Even the most inexperienced site owners I talk with have often heard about, and want to know more about, PageRank (“PR”) and what it means for their site. However, as I said in my fateful forum post, the Webmaster Central team has been telling webmasters for years that they shouldn't focus so much on PageRank as a metric for representing the success of one’s website. Today I’d like to explain this position in more detail and give you some relevant, actionable options to fill your time once you stop tracking your PR!
Why PageRank?
In 2008 Udi Manber, VP of engineering at Google, wrote on the Official Google Blog:
If you look at Google’s Technology Overview, you’ll notice that it calls out relevance as one of the top ingredients in our search results. So why hasn’t as much ink been spilled over relevance as has been over PageRank? I believe it’s because PageRank comes in a number, and relevance doesn’t. Both relevance and PageRank include a lot of complex factors—context, searcher intent, popularity, reliability—but it’s easy to graph your PageRank over time and present it to your CEO in five minutes; not so with relevance. I believe the succinctness of PageRank is why it’s become such a go-to metric for webmasters over the years; but just because something is easy to track doesn’t mean it accurately represents what’s going on on your website.
What do we really want?
I posit that none of us truly care about PageRank as an end goal. PageRank is just a stand-in for what we really want: for our websites to make more money, attract more readers, generate more leads, more newsletter sign-ups, etc. The focus on PageRank as a success metric only works if you assume that a higher PageRank results in better ranking, then assume that that will drive more traffic to your site, then assume that that will lead to more people doing-whatever-you-want-them-to-do on your site. On top of these assumptions, remember that we only update the PageRank displayed on the Google Toolbar a few times a year, and we may lower the PageRank displayed for some sites if we believe they’re engaging in spammy practices. So the PR you see publicly is different from the number our algorithm actually uses for ranking. Why bother with a number that’s at best three steps removed from your actual goal, when you could instead directly measure what you want to achieve? Finding metrics that are directly related to your business goals allows you to spend your time furthering those goals.
If I don’t track my PageRank, what should I be tracking?
Take a look at metrics that correspond directly to meaningful gains for your website or business, rather than just focusing on ranking signals. Also consider metrics that are updated daily or weekly, rather than numbers (like PageRank) that only change a few times a year; the latter is far too slow for you to reliably understand which of your changes resulted in the number going up or down (assuming you update your site more than a few times a year). Here are three suggestions to get you started, all of which you can track using services like Google Analytics or Webmaster Tools:
A “conversion” is when a visitor does what you want them to do on your website. A conversion might be completing a purchase, signing up for a mailing list, or downloading a white paper. Your conversion rate is the percentage of visitors to your site who convert (perform a conversion). This is a perfect example of a metric that, unlike PageRank, is directly tied to your business goals. When users convert they’re doing something that directly benefits your organization in a measurable way! Whereas your PageRank is both difficult to measure accurately (see above), and can go up or down without having any direct effect on your business.
Bounce rate
A “bounce” is when someone comes to your website and then leaves without visiting any other pages on your site. Your bounce rate is the percentage of visits to your site where the visitor bounces. A high bounce rate may indicate that users don’t find your site compelling, because they come, take a look, and leave directly. Looking at the bounce rates of different pages across your site can help you identify content that’s underperforming and point you to areas of your site that may need work. After all, it doesn’t matter how well your site ranks if most searchers are bouncing off of it as soon as they visit.
Clickthrough rate (CTR)
In the context of organic search results, your clickthrough rate is how often people click on your site out of all the times your site gets shown in search results. A low CTR means that, no matter how well your site is ranking, users aren’t clicking through to it. This may indicate that they don’t think your site will meet their needs, or that some other site looks better. One way to improve your CTR is to look at your site’s titles and snippets in our search results: are they compelling? Do they accurately represent the content of each URL? Do they give searchers a reason to click on them? Here’s some advice for improving your snippets; the HTML suggestions section of Webmaster Tools can also point you to pages that may need help. Again, remember that it doesn’t matter how well your site ranks if searchers don’t want to click on it.
Entire blogs and books have been dedicated to explaining and exploring web metrics, so you’ll excuse me if my explanations just scrape the surface; analytics evangelist Avinash Kaushik’s site is a great place to start if you want to dig deeper into these topics. But hopefully I’ve at least convinced you that there are more direct, effective and controllable ways to measure your site’s success than PageRank.
One final note: Some site owners are interested in their site’s PR because people won’t buy links from their site unless they have a high PageRank. Buying or selling links for the purpose of passing PageRank violates our Webmaster Guidelines and is very likely to have negative consequences for your website, so a) I strongly recommend against it, and b) don’t be surprised if we aren’t interested in helping you raise your PageRank or improve your website when this is your stated goal.
We’d love to hear what metrics you’ve found useful and actionable for your website! Feel free to share your success stories with us in the comments here or in our Webmaster Help Forum.

Why PageRank?
In 2008 Udi Manber, VP of engineering at Google, wrote on the Official Google Blog:
“The most famous part of our ranking algorithm is PageRank, an algorithm developed by Larry Page and Sergey Brin, who founded Google. PageRank is still in use today, but it is now a part of a much larger system.”PageRank may have distinguished Google as a search engine when it was founded in 1998; but given the rate of change Manber describes—launching “about 9 [improvements] per week on the average”—we’ve had a lot of opportunity to augment and refine our ranking systems over the last decade. PageRank is no longer—if it ever was—the be-all and end-all of ranking.
If you look at Google’s Technology Overview, you’ll notice that it calls out relevance as one of the top ingredients in our search results.

salam every one, this is a topic from google web master centrale blog:
We've received numerous requests to improve our indexing of Adobe Flash files. Today, Ron Adler and Janis Stipins—software engineers on our indexing team—will provide us with more in-depth information about our recent announcement that we've greatly improved our ability to index Flash.
Q: Which Flash files can Google better index now?
We've improved our ability to index textual content in SWF files of all kinds. This includes Flash "gadgets" such as buttons or menus, self-contained Flash websites, and everything in between.
Q: What content can Google better index from these Flash files?
All of the text that users can see as they interact with your Flash file. If your website contains Flash, the textual content in your Flash files can be used when Google generates a snippet for your website. Also, the words that appear in your Flash files can be used to match query terms in Google searches.
In addition to finding and indexing the textual content in Flash files, we're also discovering URLs that appear in Flash files, and feeding them into our crawling pipeline—just like we do with URLs that appear in non-Flash webpages. For example, if your Flash application contains links to pages inside your website, Google may now be better able to discover and crawl more of your website.
Q: What about non-textual content, such as images?
At present, we are only discovering and indexing textual content in Flash files. If your Flash files only include images, we will not recognize or index any text that may appear in those images. Similarly, we do not generate any anchor text for Flash buttons which target some URL, but which have no associated text.
Also note that we do not index FLV files, such as the videos that play on YouTube, because these files contain no text elements.
Q: How does Google "see" the contents of a Flash file?
We've developed an algorithm that explores Flash files in the same way that a person would, by clicking buttons, entering input, and so on. Our algorithm remembers all of the text that it encounters along the way, and that content is then available to be indexed. We can't tell you all of the proprietary details, but we can tell you that the algorithm's effectiveness was improved by utilizing Adobe's new Searchable SWF library.
Q: What do I need to do to get Google to index the text in my Flash files?
Basically, you don't need to do anything. The improvements that we have made do not require any special action on the part of web designers or webmasters. If you have Flash content on your website, we will automatically begin to index it, up to the limits of our current technical ability (see next question).
That said, you should be aware that Google is now able to see the text that appears to visitors of your website. If you prefer Google to ignore your less informative content, such as a "copyright" or "loading" message, consider replacing the text within an image, which will make it effectively invisible to us.
Q: What are the current technical limitations of Google's ability to index Flash?
There are three main limitations at present, and we are already working on resolving them:
1. Googlebot does not execute some types of JavaScript. So if your web page loads a Flash file via JavaScript, Google may not be aware of that Flash file, in which case it will not be indexed.
2. We currently do not attach content from external resources that are loaded by your Flash files. If your Flash file loads an HTML file, an XML file, another SWF file, etc., Google will separately index that resource, but it will not yet be considered to be part of the content in your Flash file.
3. While we are able to index Flash in almost all of the languages found on the web, currently there are difficulties with Flash content written in bidirectional languages. Until this is fixed, we will be unable to index Hebrew language or Arabic language content from Flash files.
We're already making progress on these issues, so stay tuned!
Update in July 2008: Everyone, thanks for your great questions and feedback. Our focus is to improve search quality for all users, and with better Flash indexing we create more meaningful search results. Listed below, we’ve also answered some of the most prevalent questions. Thanks again!

Flash site in search results before improvements
Flash site after improved indexing, querying [nasa deep impact animation]
Helping us access and index your Flash files
@fintan: We verified with Adobe that the textual content from legacy sites, such as those scripted with AS1 and AS2, can be indexed by our new algorithm.
@andrew, jonny m, erichazann, mike, ledge, stu, rex, blog, dis: For our July 1st launch, we didn't enable Flash indexing for Flash files embedded via SWFObject. We're now rolling out an update that enables support for common JavaScript techniques for embedding Flash, including SWFObject and SWFObject2.
@mike: At this time, content loaded dynamically from resource files is not indexed. We’ve noted this feature request from several webmasters -- look for this in a near future update.
Update on July 29, 1010: Please note that our ability to load external resources is live.
Interaction of HTML pages and Flash
@captain cuisine: The text found in Flash files is treated similarly to text found in other files, such as HTML, PDFs, etc. If the Flash file is embedded in HTML (as many of the Flash files we find are), its content is associated with the parent URL and indexed as single entity.
@jeroen: Serving the same content in Flash and an alternate HTML version could cause us to find duplicate content. This won't cause a penalty -- we don’t lower a site in ranking because of duplicate content. Be aware, though, that search results will most likely only show one version, not both.
@All: We’re trying to serve users the most relevant results possible regardless of the file type. This means that standalone Flash, HTML with embedded Flash, HTML only, PDFs, etc., can all have the potential to be returned in search results.
Indexing large Flash files
@dsfdgsg: We’ve heard requests for deep linking (linking to specific content inside file) not just for Flash results, but also for other large documents and presentations. In the case of Flash, the ability to deep link will require additional functionality in Flash with which we integrate.
@All: The majority of the existing Flash files on the web are fine in regard to filesize. It shouldn’t be too much of a concern.
More details about our Flash indexing algorithm
@brian, marcos, bharath: Regarding ActionScript, we’re able to find new links loaded through ActionScript. We explore Flash like a website visitor does, we do not decompile the SWF file. Unless you're making ActionScript visible to users, Google will not expose ActionScript code.this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
@dlocks: We respect rel="nofollow" wherever we encounter it in HTML.
