As a marketing tool Twitter gets much more interesting and useful when you can filter out 99% of the junk that doesn’t apply to your objectives and focus on the stuff that matters.
The basic search.twitter.com functionality is fine for searching things that are being said about your search terms. The advanced search function offers more ways to slice and dice the stream, but still leaves some room for improvement as it only searches what’s being said and where. From a marketing standpoint who is saying it might be more useful.
Now that the search engines are all pretty geeked up over real time search you can create some very powerful searches and alerts combining Google and Twitter.
1) Target by occupation
Let’s say you have a business that sells an awesome service to attorneys. A simple search on Twitter will turn up thousands of mentions of the word attorney, but many of them will be from people talking about this or that attorney or the need to hire or not hire one. That’s probably not very helpful for your purposes.
However, if you cruise over to Google and use a handful of operators from the Google shortcut library (more on that here) you can create a search that plows through Twitter and gives you a list of all the users that have the word “attorney” in their title (username and/or real name) – Click on this search phrase and see what happens – intitle:”attorney * on twitter” site:twitter.com – what you’ll find is a handy list of attorneys of one sort or another on Twitter.
Without getting too technical, this search basically asks Google to look in the title attribute of profile pages on Twitter – obviously you can use any word to replicate this. The * tells Google to find the words “attorney on Twitter” without regard to order or other words – “on Twitter” appears in the title of every profile page so we need that term to make sure we search profile pages only.
2) Target by bio
In some cases searching through the optional biographical information can be more helpful than the username or real name fields. Maybe you’re looking for a very specific term or some of the folks you are targeting only reference their profession in their bio.
Google search to the rescue here again. This time add the intext attribute, the word bio and our key phrase to search bios – So a search for web designers would look like this – intext:”bio * web designer” site:twitter.com. When you look at this list you might notice that none of the people on the list would have been found by searching in their title, as in the first tip, for web designer. Try it both ways to test for best results.
3) Target by location
Location search by itself is simple using the Twitter advanced search tool – if you want a list of people in Austin you would use this in Twitter – near:”Austin, TX” within:25mi and Twitter would use the location field to show you Austin Tweeters.
But . . . let’s say you wanted to target salons in Austin or maybe the whole of Texas – it’s back to Google to mix and match – (intitle:”salon * on twitter” OR intext:”bio * salon”) intext:”location * TX” site:twitter.com – we search the title, bio and location to get a very targeted list of Salons in Texas on Twitter. Note the OR function for multiple queries.
4) New sign ups
Another handy thing about using any of the searches above is that you can also use the exact operators to create Google Alerts. By going to Google and putting in your search string as described above you’ll get everything they have now, but by setting up an alert you’ll get an email or RSS alert when a new attorney (or whatever you’re targeting) joins Twitter – I can think of some powerful ways to reach out to that new person just trying to find some new friends!
5) Keep up on your industry
Some of the best information shared on Twitter comes in the form of shared links. In other words people tweet out good stuff they find and point people to it using a link. I love to use a filtered Twitter search to further wade through research on entire industries, but reduce the noise by only following tweets that have links in them and eliminating retweets that are essentially duplicates – “small business” OR entrepreneur OR “start up” filter:links – this gets that job done and produces an RSS feed if I want to send it to Google Reader. Don’t forget the “quotation marks” around two or more word phrases or you will get every mention of small and business.
6) Competitive eavesdropping
Lots of people set up basic searches to listen to what their competitors are saying and what others are saying about the competition. I would suggest you take it one step further and create and follow a search that also includes what the conversation they are having with the folks they communicate with – not just what people are saying about them, but to them and vice versa – from:comcastcares OR to:comcastcares.
7) Trending photos
Photos have become very big on Twitter and the real time nature of the tool means photos show up there before they show up most anywhere. If you want to find an image related to a hot trend, or anything for that matter, simply put the search phase you have in mind follow by one of the more well known Twitter image uploading services such as TwitPic and you’ll get nothing but images. So, your search on Twitter might be – olympics twitpic OR ow.ly (You can add more photosharing sites to expand the search).
There, Twitter just go way more interesting didn’t it?

Here, I'll explain what you can do to optimize your server for writing.

If you have used top and iotop to determine that you have a write performance problem, there are a few things that you can do. First of all, there is the design of your server. Too many servers are installed with one huge partition with the operating system and data intensive processes together. This is not ideal because there will be only one file system active, one process that flushes data from RAM to disk and only one journaling process. So if your server suffers from bad write performance, backup all your data and get the installation disk. While installing, make sure that the data that is needed by the write-intensive process is on a different partition than the rest of your files.

By default, most Linux servers are tuned for average use – for a use-case in which there are as many reads as there are writes. But, your server may need different settings.

While installing your server with custom partitioning, the file system you are using also plays a role. There are two file systems that offer considerable better performance with regard to writes, these are XFS and Ext4. Fortunately, Ext4 is the default file system on all recent Linux distributions, just make sure that your partition is formatted with this file system.

But, the act of installing your server with different partitions may not be enough. By default, most Linux servers are tuned for average use – for a use-case in which there are as many reads as there are writes. But, your server may need different settings.

There are two parameters that relate to the current performance behavior. First, there is the I/O scheduler, a setting that exists for each device you have in your server. Next, there is the journaling mode your file system is using. Let's have a look at the I/O-scheduler first.

I/O scheduler settings
Every device has its own I/O-scheduler. You can find the current settings in the /sys/block/device/queue directory, in the file scheduler. To show the current contents, use the cat scheduler command. This gives you a result that looks as in the following listing:

root@texas:/sys/block/sda/queue# cat scheduler

noop anticipatory deadline [cfq]

As you can see, there are four different settings available, and currently the cfq setting is selected. That means that the I/O scheduler allocates equal time slots for reads and for writes, which means bad performance if your server is writing most of the time. So let's start by changing this setting to deadline. Using deadline, means that the scheduler is delaying writes as long as it can, with the purpose of writing as efficiently as possible. To change the current setting, you can use the following command:

echo deadline > /sys/block/sda/queue/scheduler

Journaling settings
You are likely to see some progress after applying this change. But there is more. All modern file systems are using journaling. Journaling ensures the integrity of a file system. There are three different modes in journaling, in which data=journal is the most secure, but definitely the slowest method, and data=writeback is the least secure, but absolutely the fastest mode. The default value is normally set to data=ordered, which is the ideal compromise between speed and data integrity.

For performance reasons it is a good idea, especially if iotop gives you a high amount of data throughput for the kjournald2 process (the process that takes care of journaling). To apply this option, you must use it while mounting the file system, so you have to include it in your fstab. The following line shows how a file system can be mounted with this option applied to it:

/dev/sda3 / ext4 acl,user_xattr,data=writeback 1 1

Many servers that suffer from bad performance, actually suffer from bad write performance, but fixing the problem is not difficult. Here we've covered how to optimize your server for better writes, applying some simple design guidelines and optimization parameters.

How can you get your blog indexed by Google in 24 hours? There is a lot of conflicting search engine optimization information available, especially when it comes to trying to beat the natural ranking systems and having your blog rank high in Google right from the start. While it’s possible to make a blog and have it indexed almost straight away, most people go about doing so with a poor overall strategy for success.
Ranking high on Google is all about long-term thinking, and going out to win everything in the first day will often see you wasting time and opportunity without getting anything in return. However, it’s very much possible to be indexed by Google in 24 hours or less. After you make a blog, just follow these simple ideas and you’ll see your website show up in the search results within a day.

1: SUBMIT YOUR BLOG TO GOOGLE

Obviously you’ve got to submit your new blog to Google before it can be indexed. Some free blogging platforms will submit your blog for free, while others, especially self-hosted blogging platforms, require you to do it yourself. Either way, it’s an easy 5-minute job that can be done alongside other, more time consuming tasks. Use the Google webmasters tools to verify your site. Here’s how:
Step 1: Go to google.com/webmasters. Sign in using your Google Account or create an account if you don’t have one already.
Step 2: Add your blog site by clicking the “Add a site” button. Then type in the domain name you wish to add, and click “Continue”.
Step 3: Once added you will need to verify that you own this site. This can be done one of two ways, Meta Tag or Upload a HTML file. The Meta Tag way is, by far the easiest.
Step 4: Meta Tag verification. This method requires you to add a piece of code to your header.php file. Copy the Meta Tag code Google has asked you to copy to your blog site.
Step 5: In your WordPress dashboard go to “Appearance”, then “Editor” using the menu tabs on the left hand side.
Then click on Header (header.php) on the right hand side to open up the h eader t emplate. Find the head tag highlighted, and BELOW it “paste” in the verification Meta tag Google has given you.
Step 6: Then scroll down and click on “Update File”
Step 7: Go back to the Google Webmasters Tool website and click “Verify” and Google will confirm that you own the site.
Step 8: After verifying, Google will display a confirmation page.

2: SUBMIT YOUR BLOG SITEMAP TO GOOGLE

If you are using WordPress, install the Google XML sitemap plugin that creates a sitemap of your blog that search engines can read.
You now want to add your blog’s sitemap. This is how:
Step 1: From within the Google Webmaster tools website, click on the domain name you have just added and it will open up a Dashboard for your site. On the left hand side menu, click on “Site Configuration” and then “Sitemaps”.
Step 2: Click “Submit a Sitemap” and enter the name of your sitemap. It should be sitemap.xml
It will take a few hours for the sitemaps to be analyzed and added. Then you can return here and make sure there are no errors, see how many URLs are being indexed and the time that Google last visited you. Even without the sitemap you will begin to get a list of the top search queries that your site is being found for, incoming links to your site, and the keywords that Google thinks your site is optimized for.
By verifying your site and adding your blog’s sitemap, you are telling Google your blog has arrived and it will quickly be indexed.

3: USE SOCIAL BOOKMARKING TO GENERATE LINKS RIGHT AWAY

Social bookmarking services are a great way to generate links to your new blog in record time. From simple community bookmarking websites to the giants of the web, submitting your website to social bookmarking services like StumbleUpon, Digg and Twitter can help you generate powerful, natural linkbacks. Log on and “favorite” your blog, and be sure to encourage your friends and colleagues to do the same.

4: GET POSTING ON FORUMS

Get your blog link in your forum signature and start posting it on as many forums as you can. Of course, spamming is never a good long-term idea, but some smart, relevant forum posts are a great way to bring in new SEO juice and links for your new blog. For some reason, Google tends to prioritize websites that are generating links already, so get out there and create as many as you possibly can for your new blog.

5: INSTALL SEO PLUGINS FOR YOUR BLOG

Most blogs will come with a SEO pack available, and Wordpress has a free one for download if you’re having trouble optimizing your blog. Search engine optimization is absolutely essential for generating blog traffic, and without putting time and thought into your SEO efforts it’s easy to lose what could be a great opportunity. Even though we’re focusing on short-term SEO speed, it’s good to think long-term right from the beginning. Download and use the All-in-one-Seo-Pack plugin.
