One thing I was always confused about was the crawlability of your website. What is exactly is "crawlability" and how does that effect your SEO? Also, what are some ways to improve your websites crawlability?
Crawlability just refers to how easy it is for the search engine spiders to navigate your entire website to get all of your pages indexed. If you have a decent internal link structure, your website most likely is crawlable. There are things that can limit crawlability: -javascript navigation -flash navigation -drop down menu navigation -image navigation links only without 'backup' text navigation...this one might not be an issue anymore, but it is best to play it safe and help the search engine spiders where you can -severe html coding errors...if your html coding is especially weak, there may be crawling issues. It is usually a good idea for your code to be w3c compliant. -query string session ids -page redirects There may be more issues that limit crawlability but those are the main ones. If you are concerned about crawlability, sign up for a Google Webmaster Tools account and submit a sitemap. They will tell you if there are any problems indexing your pages.
How do you redirect a single page vansterdam.. I've never managed to do that. I'd appreciate your help.
Google something like '301 redirect .htaccess file'. It should be easy enough to find some suitable code. Avoid meta refresh redirects though. Those redirects are mostly used by spammers who use cloaking.
I sitemap helps in "crawlability" Also each page should be able to link to the home page and to easiliy link to other pages. Not an expert in this but seems to work for me.
You can set the Crawability rate in Google Webmaster Tools, but only after you have submitted your site there and added a sitemap.
