Although there are many different banner sizes in every website, there are some sizes which we may call the "standard ones".
Interactive Advertising Bureau (IAB) which represents a considerable amount of agencies and media companies for use in the creating, planning, buying and selling of interactive marketing and advertising, has the nice list of banner sizes which can be called as standard.
The list may help you while designing websites for creating the banner areas in most common sizes.
For URL rewriting, directory protection, url forwarding or other advanced purposes, every web developer or website owner uses .htaccess files frequently.
.htaccess coding can be very complex depending on what is wanted to be achieved. For standard, simple usage, the commands are easy to use and even easier with the online .htaccess Editor.
htaccess Editor, with an input based ajax interface, asks the user which directory needs to be password protected, error page to be shown and even redirect directives. Depending on the inputs, a .htaccess file is created on the fly.
Robots.txt file usage is sometimes ignored. On the other hand, it is an important factor for the webpages being indexed properly and very easy to setup.
I know that robots.txt is not something new. But, I’ve been preparing a SEO sheet for a while and wanted to share this small & useful portion with you.
What is robots.txt?
Robots.txt is a file that is used to exclude content from the crawling process of search engine spiders / bots. Robots.txt is also called the Robots Exclusion Protocol.
Why to use robots.txt?
In general, we prefer that our webpages are indexed by the search engines. But there may be some content that we don’t want to be crawled & indexed. Like the personal images folder, website administration folder, customer’s test folder of a web developer, no search value folders like cgi-bin, and many more. The main idea is we don’t want them to be indexed.
Is robots.txt file a certain solution?
No. Standards based bots like Google’s, Yahoo’s or other big search engine’s robots listen to your robots.txt file. This is because they are programmed to. If configured so, any search engine bot can ignore the robots.txt file. Result: there is no guarantee.
How to use robot.txt file?
Robots.txt file has some simple directives which manages the bots. These are:
User-agent: this parameter defines, for which bots the next parameters will be valid. * is a wildcard which means all bots or Googlebot for Google.
Disallow: defines which folders or files will be excluded. None means nothing will be excluded, / means everything will be excluded or /folder name/ or /filename can be used to specify the values to excluded. Folder name between slashes like /folder name/ means that only folder name/default.html will be excluded. Using 1 slash like /folder name means all content inside the folder name folder will be excluded.
There are also some other parameters which are only supported by all browsers. These are:
Allow: this parameter works just the opposite of Disallow. You can mention which content will be allowed to be crawled here. * is a wildcard.
Request-rate: defines pages/seconds to be crawled ratio. 1/20 would be 1 page in every 20 second.
Crawl-delay: defines howmany seconds to wait after each succesful crawling.
Visit-time: you can define between which hours you want your pages to be crawled. Example usage is: 0100-0330 which means that pages will be indexed between 01:00 AM – 03:30 AM GMT.
Sitemap: this is the parameter where you can show where your sitemap file is. You must use the complete URL addres for the file.
Robots.txt example:
User-agent: * #allows all search engine spiders.
Disallow: /secretcontent/ #disallow them to crawl secretcontent folder.
Images used in websites have a serious keyword value when they are used right.
There are 3 variables, which we think of, can show search engines what the image is about? These are title, alt, and the image name. Matt Cutts, the head of Google’s webspam team describing us which ones are important in this video:
What is alt attribute?
The alt attribute is used in HTML and XHTML documents to specify text that is to be rendered when the element to which it is applied cannot be rendered. In HTML 4.01, the attribute is required for the img and area element types. It is optional for the input element type and the deprecated applet element type.

With many different operating systems, many browsers and different browser versions the design of a website can look different to every user.
Testing your website in different browsers easily is possible.
