It is important to have your website free from HTML (web code) errors. While it is not required that your website be error-free, it is highly recommended so that search engines will have an easier time indexing your website. Many website companies have error-free websites but the websites that they create for clients aren't error-free. Make sure your website company has an error-free website themselves and creates error-free websites for their clients. You can check the validity by reading the paragraph below.
The World Wide Web Consortium provides this service at http://validator.w3.org/. Just type in your website URL and test your website if you have one. Your website should be error free or nearly error free. This can help maintain your status rankings of Google, Yahoo, and MSN. In fact, every page should be checked and validated. But if you have 10 or more errors, you should take the time to correct these errors.
Groomer Web Services checks every page of your website to make sure that it is error-free. While not all web pages can be error free, our goal is to make sure that you have less than 3 errors on a web page.
Another search engine technique that we use is the validation used by Domain Tools. Type in your website URL and click the Site Profile tab and check your profile score. We feel this score should be at least 80%. If not, you definitely need to perform some corrections to your website.
Search Engine Optimization can never be guaranteed by any website company. It is constantly changing and if a website company says that they can guarantee that your webite will be on the first page of search engine results, they are lying. If your website is written well and is error-free, it will be on the first couple of pages of the search engines.
