Blogs tell about SEO, SMM, SEM, page rank algoritham, meta tags, page navigation, link building, on-page & off-page optimization, etc.

1. Content Pages: The most important page on your site, assuming it contains the content the user seeks at that moment. Also known to contain lateral navigation, allowing users to jump from content page to content page to gather more information to support their activity.
2. Galleries: A listing of links to content pages, this page is the most critical “link in the chain” of pages. Most navigation failures we see are due to poorly-designed gallery pages. Users want to decide on the content page from within the gallery, to eliminate pogosticking.
3. Departments: Sites that have too many links for a single gallery need to have a Department page, which lists all the galleries. While you’d think these would work the same as galleries, users somehow understand that a list of galleries is different from a list of content pages and use these pages more for winnowing their selection down.
4. Stores: Really large sites (such as those with more than 50,000 content pages) find that they need multiple departments. If they have enough departments, they’ll need multiple pages to describe them–we call those store pages. News sites, for example, often have store pages (such as US, World, Business, Sports, and Weather). Stores are segmented content areas that users rarely bounce between, therefore requiring everything that user needs in one location.
5. Gallery-level Search Results: The most common of search result pages, the Gallery-Level Search Results page are similar to plain-old galleries, except they contain the search engine generated results. This means they don’t benefit from the handcrafted selection process of real galleries, but instead are computer-generated and, therefore, have a harder time presenting the necessary information for choosing.
6. Department-level Search Results: On really large sites, it’s not uncommon for the search engine to try to divide the results into departments, creating what we call Department-level Search Results. These results are presented to assist in the winnowing process.
7. Search Entry Page: The page where the user enters their search query. (Sometimes it’s a standalone page, but frequently it’s just a section of a larger page, such as a gallery or a department.)
8. Home Page (Landing pages): The least important page on the site (unless it contains the user’s content), the home page (which, in this day of Google & Yahoo is often a landing page and not the top-level URL page) is tasked with orienting users in the right direction–sort of a Munchkinland at the start of the yellow-brick road. Depending on the size of the site, it’s like the home page will also be a content, gallery, department, or store page.

3 Kinds of Links
1. Hierarchical Navigation  - Hierarchical applies to sites that are information-rich and are best organized as a large tree, much like a library.
2. Site-wide Navigation - Global applies to sites where you can easily and logically jump among all points; this is best if you are presenting information in fewer, broader categories.
3. Local Navigation - Local navigation sits somewhere in between. This applies when you have depth of information within broader areas.

How to make user friendly site

1. If your site is a personal website, think in terms of how you can exhibit your personality and style. & If your site is a commercial website, think in terms of how you want your customers to feel about your products and services.2. Research, Research, Research, what other websites with similar objectives have done. After come up your site. Spend some time looking at existing websites, and make notes of their respective positives and negatives; then think of how your site can incorporate the positives, while avoiding the negatives.
3. You can learn a lot about what works and what doesn’t by looking at the layout, color scheme, text, and images of other websites, and then use that knowledge to get the most out of your site.
4. The best way to do this is to start by drawing a sitemap, covering all of the pages you plan to create.
5. Try to lay out your site in a clear, logical manner, and avoid using image-based mouseover links.
6. This will help ensure that your site is easy to navigate, and will still leave you plenty of room to add your personal design touches.
7. Try to limit your pages to a total of 30kb, including text, background images, and images.
8. This will ensure that all pages will be loaded in about 5 seconds, even if the user happens to be using a dial-up connection.
9. Designing a good site, however, is a lot more difficult than merely put some pictures and text onto a page and arranging it to nice look.
10. If you do use one table, users will not be able to see any of your content until the entire table has been loaded. In order to avoid this problem, break your page into at least two tables. This will allow the user to see part of your page quickly, so that they do not get discouraged by a long wait.
11. When you have finished designing your site, be sure to take a look at it in several different browsers. Sometimes your “perfect” design will look urgly (not good) when viewed with a different browser
12. Typically a navigation bar looks something like this: You are at: Home>My Hobbies>Sports
13. Always ensure that you close HTML tags:

, , ,
14. Be sure to use standard TrueType Fonts, font sizes below 9 will not display well & bold formatting of font sizes below 11 will not be displayed.
15. Some older systems have a limited palette available, and their set-ups may vary. To ensure that your material will be viewable in a standard fashion, use Hexadecimal code for 216 “Web-safe colours”, e.g. H1 {COLOR: #FF0000}.
