Some Basic Concepts to Know About Search Engine Optimization

Some Basic Concepts to Know About Search Engine Optimization is easier to understand when the core ideas are paired with practical examples. The sections below explain the topic clearly, highlight useful steps, and point out details that can prevent common errors.

In Part I and II we explained the term SEO and how the Search Engine works in website promotion. As you know, keywords are the most important component when you want to be effective SEO, but for the website to exist and always be appreciated, we need to have good content, focusing on the readers need. This last part will cover how to present elements in web pages, URLs and methods to increase traffic.

6. Intuitive additional features and SEO

As mentioned above, search engines have no means of indexing directly additional features like images, audio, flash movies and javascript. Instead, they depend on you to provide descriptions and based on which you can index these files. In a sense, the situation is similar to the text of 10 years ago - you will provide a description in the meta tag, then search engines use them to index and process your site. If technology continues to improve, someday search engines can index images, movies. will no longer be a dream.

6.1 Image

Images are an essential part of any website and from the designers' point of view this is a mandatory item for all websites. However, here designers and search engines are two different poles because for the search engine, all information hidden in the image will disappear. When working with designers, it sometimes takes time to explain to them that it is imperative to have text links (with appropriate anchor text) rather than images. It can be difficult to find the balance of performance between art and SEO-friendly, but since even the best websites disappear in cyberspace if it is not search engine found, a compromise on visual appearance is inevitable.

After what we have said, it does not mean ignoring the whole image, and for today it is certainly impossible, as a result the site will become disordered. Instead, images should be used for illustration and decoration, not for navigation or worse - to display text (As an example,, in a fancy font). And most importantly - in the properties of the card, always provide a meaningful description text for images. The HTML specification does not require this, but it is very important for search engines. In addition, you need to place meaningful names for images instead of generic ones like image1.jpg, image2.jpg, imageN.jpg . examples of an image file with full name and supply information. enough alt attributes. Note that there are no more than 20 words in the tags because this will be suspected of ' cramming ' the keyword.

6.2 Animation and movies

The situation with animations and movies is similar to the image above. They are valid from the designers' point of view but are not sympathetic to search engines. It's easy to see that creating an impressive flash introduction page on the homepage of your website is still quite popular, but you can't imagine that it is a disadvantage to search engines - the number one enemy of the top rankings. class. Even worse, if we use flash to tell a story that can be written in plain text, crawling and indexing by search engines will be very slow. One solution is to provide the search engine with an HTML version of the flash movie, but in case you are sure you have excluded the original flash movie from indexing (this is done in the robots.txt file * ), otherwise you will be penalized for duplicate content.

There are rumors that Google is building a new search technology that will allow searching inside animations and movies, the.swf format will contain new metadata that can be used by the search engine. But it is better to limit the use of too much Flash or at least provide a descriptive text description for the movie with a card.

6.3 Frames

Using frames will make websites slow down, but the technology has gradually disappeared five or 10 years ago. In the past designers often used this card, but with search engines it did not. The search engine has difficulty indexing pages that use frames because the website URL does not change even if any frame is opened. For search engines this is a shock because the fact that there are many pages coexisting on one URL, while for search engines, each URL is only one page. Of course, search engines can track links to other websites in the frameset and index them, but that is still a major obstacle to ranking websites.

If you still want to use frames, make sure you always provide a meaningful description for the site in the tag. Even for beginners, we just need to memorize the card

is the place to assign an alternate version (or at least a brief description) to your site on the search engine and the browser does not support frames. Such as:

6.4 JavaScript

JavaScript is an object-based scripting language developed from prototype ideas. On the browser, many websites use JavaScript to design dynamic websites and some visual effects through the DOM. JavaScript used to perform some tasks cannot be performed with only HTML such as checking input information, automatically changing images, etc. Originally, HTML was not a programming language for building To build web applications, no one can use HTML to process a database written or even for a session to store information.

Search engines now ignore only the JavaScript they encounter on a page. If you have links within JavaScript code, it probably won't be spider *. Second, if JavaScript is in the HTML file (not in the .js files called when needed) then the HTML file and the spider itself may just ignore it and move to the next web page. You can use the card
