Background
Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. Usually, the earlier a site is presented in the search results, or the higher it "ranks", the more searchers will visit that site. SEO can also target different kinds of search, including image search, local search, and industry-specific vertical search engines.

Spidering is the process where a program or automated script (called web crawler, web spider or web robot) which browses the World Wide Web in a methodical, automated manner. Search engines use spidering as a method of providing up-to-date data. Web crawlers are mainly used to create a copy of all the visited pages for later processing by a search engine that will index the downloaded pages to provide fast searches.

Search engine indexing entails how data is collected, parsed, and stored to facilitate fast and accurate retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and computer science. The goal of storing an index is to optimize the speed and performance of finding relevant documents for a search query.

Recommendations
In general, Search Engine Optimization (SEO) consists of several procedures which should be applied simultaneously on the regular basis.

As a website development company Polspace applies SEO efforts may involve a site's coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering a site.

Other, more noticeable efforts may include adding unique content to a site, ensuring that content is easily indexed by search engine robots, and making the site more appealing to users.

Creating an effective title
Many search engines weigh the data in your title more heavily than other data in your page. Make sure that your title has keywords that represent your site effectively.

Avoiding frames
Most search engine simply cannot index a frames page. They get to your site and can't go anywhere.

Keeping the important content near the top of your pages
Some engines will place a higher rating of importance based on where they find the text in your page. Closer to the top is usually better.

Making the Website Content a #1 priority
We can help you in many ways, but your quest for high placement must start with a good website. It is important to have a lot of text describing what you do. Use your keywords in the content, but don't repeat them over and over. Many search engines rate sites based on 'keyword density'. This is usually a formula that looks at META Keywords, words in your TITLE, words in paragraph text, words in links to other pages, and even words in the 'ALT' text on your images. They will even look at different forms of your keywords. For example, if an important keyword for you is 'FISH', the word 'FISHING' in the body of your document will raise the confidence in the word 'FISH' on some engines.

Keep your site updated
Make sure that your site is up to date. No one likes to go to a page that never changes or that is very out of date. Make sure that the data in your page portrays the message that you want to send.

Links from others websites
We can't emphasize enough the importance of links: both from your page to other pages, and from other pages to yours.

• First consider links on your pages
  When many search engines see them, they consider your site more 'real'. It also gives the search engine spiders a place to go. Make your links meaningful. Make sure they relate to what you do (and keywords that are important to you). You can't have too many links on your pages.
• Links from others websites
  Some search engines place a very heavy rating of importance on how many other sites in their index have links to your website. When the company' website is linked to by a thousand websites is considered more important than a company that is only linked to by one website. A hyperlink to a page counts as a vote of support. Therefore, a search engine will always try to list the more important ones first.

We don't recommend

Fooling search engines
We don't try to 'fool' search engines, and they work for a little while...sometimes. But then the search engines catch on and write routines that penalize sites that use this practice. Examples of this include, but are not limited to: repeating keywords over and over; using invisible text (white text on white background); using very small text to jam the keywords in a small area.

Over saturating the website with images
We don't create pages that are almost all images. That is because the search engines don't have eyes. They don't see the beautifully formatted text in your image. All they see is 'yourimage.jpg', and 'yourimage.jpg' doesn't go far in terms of content and relevancy.

Loading the top of your pages with data the engines can't read
As with the last example, something higher up in your page can be more important that something further down. Therefore, HTML formatting, images, scripts, etc. toward the top of your page can result in lower ratings

Spamdexing
Generally, you should NOT submit every single page of your website to search engines. In most cases, you should submit only your home page and perhaps a couple of other very important pages at most. The rest of your website will be indexed by the search engine's spider naturally after the first page is submitted. Over-submitting your website can get you blocked from being listed!

Invisible/Tiny Text and Keyword Stuffing
Once a very popular form of inserting tons of key words and phrases into your pages, this is now considered a BIG no-no even though you'll still see it from time to time! This is achieved by placing very small text at the bottom of a page and/or text the same color as the page's background. This, too, can get your website blocked from search engine listings. Let your website's content speak for itself!

Use of Others' Copyrights/Trademarks Another unethical method of bringing traffic to your website involves embedding your competition's name, copyrights and/or trademarked words and phrases into your meta keywords tag. The idea behind this is that if your potential customers do a search for a competitor's product, your page will show up as well and you may make the sale instead. There have been some recent lawsuits regarding this in favor of the copyright/trademark holder. As tempting as it sounds, you don't want to get caught doing this!

What we do

When your site is ready:

• Submit it to search engines (xxx).
• Submit a Sitemap as part of the Google webmaster tools. Google uses your Sitemap to learn about the structure of your site and to increase their coverage of your webpages.
• Submit your site to relevant directories such as the Open Directory Project and Yahoo!, as well as to other industry-specific expert sites.
• Make a site with a clear hierarchy and text links. Every page should be reachable from at least one static text link.
• If you decide to use dynamic pages (i.e., the URL contains a "?" character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them few.

Technical aspects

• Use a text browser such as Lynx to examine your site, because most search engine spiders see your site much as Lynx would.
• Make sure our web server supports the If-Modified-Since HTTP header. This feature allows your web server to tell the search engine whether your content has changed since it last crawled your site. Supporting this feature saves you bandwidth and overhead.
• We use the robots.txt file on your web server. This file tells crawlers which directories can or cannot be crawled. We make sure it's current for your site so that we don't accidentally block the Googlebot crawler.
• If your company buys a content management system, make sure that the system can export your content so that search engine spiders can crawl your site.
• Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines.
