Adding/changing content (banners, text, etc.) will drop my site's rankings within search engines (for example - MSN Search) after crawler visits my site again? I have few sites ranked top-5 in MSN. And I need to make few changes like adding banner on top of the page & changing few text parts, but I am afraid that this will cause my sites to drop in rankings. I don't want to take this risk... What is your experience here? Thanks a lot!
Why would it drop in rankings? Read up on some SEO info and you'll see what will and won't affect your rankings, generally speaking of course. Changing banners, etc, shouldn't, by itself, drop you in the rankings.
they will drop for a few days, then come back. Even stronger if you make the changes seo-wise. Save the original page in case they don't like the changes. -RonMo
You may be confusing changing your site's content with changing your site's URLs. If you change URLs (e.g. http://mysite .com to http://www.mysite .com), then yes, you will need to take measures (such as a 301 redirect) to make sure the SEs are aware of the change. Other than that, changes to your site should only affect your rankings from an SEO perspective. HTH, Sam
