Google Says: Try to use text instead of images to display important names, content, or links. The Google crawler doesn't recognize text contained in images.
Again we see where googlebot does not crawl text in flash, JavaScript nor any graphic images. Also by following Google Says here there is a mutual benefit extended to other search engines, since those search spiders also usually do not crawl these areas.
Google Says: Make sure that your TITLE and ALT tags are descriptive and accurate.
When writing Title tags you only want to use 96 characters or about twelve (12) words, such as "Perth Amboy New Jersey Pizza Restaurant Take Out Delivery" Also change your titles per page like so "Pizza Shop Perth Amboy NJ Offers Pizza Food Eat In Free Delivery"
As for Alt image tags, there is a fine line here. Alt image tags are meant for those with vision accessibility issues and related text to speech reading software. The software reads what is in the image ALt tag to the user so we want to use "pizza shop logo image" and not pizza, pizza shop, pizza restaraunt, fresh pizza, fresh dough, pizza, calzone, pizza image. Doing this is seen as spam and will result in a filter to lowered results.
Google Says: Check for broken links and correct HTML.
If you were running a real bricks and mortar business, you wouldn't have broken pieces of stuff all over the floors of your store or business. It’s the same thing in web pages. Broken links or poor html coding of pages will cause the search spiderbots to trip and get hurt, thus not able to crawl your page. This is a liability which, while you won't hear from a lawyer, Google and other search engines will not recommend your website to other customers. Validate HTML code at http://validator.w3.org. Also, be sure to validate CSS code if used.
Google Says: 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.
This is a topic worthy of several articles which I cannot cover here, as much as I would like to. If you are using a dynamic on a Unix server, you maybe able to use a Mod Rewrite to change dynamic URLs to static on the fly. You can find more information on doing this here. You will also need to check with your web host provider. If using Windows servers, you would need to do an Isapi Rewrite and should consult your web hosting provider about this issue.
