Lets say you landed the first few results on page one of a search. But later on, when searching your site, you see it buried back a page or more. Has this ever happened to you? One day your site is almost #1 in results and then a week, month or year later it drops to the second page or even further back. Has anything like this happened to you? I don't know if it's something that does happen, but I assume many people are fighting to at least be on the first page. But I think if your SEO work is strop, and you've done a decent job marketing your site, you should be able to stay near the top of search results.
