Hi, Currently I am working on a small project, and to get the layout I want, I've implemented this script: <script type="text/javascript"> var bustcachevar=1 var loadedobjects="" var rootdomain="http://"+window.location.hostname var bustcacheparameter="" function ajaxpage(url, containerid){ var page_request = false if (window.XMLHttpRequest) page_request = new XMLHttpRequest() else if (window.ActiveXObject){ try { page_request = new ActiveXObject("Msxml2.XMLHTTP") } catch (e){ try{ page_request = new ActiveXObject("Microsoft.XMLHTTP") } catch (e){} } } else return false page_request.onreadystatechange=function(){ loadpage(page_request, containerid) } if (bustcachevar) bustcacheparameter=(url.indexOf("?")!=-1)? "&"+new Date().getTime() : "?"+new Date().getTime() page_request.open('GET', url+bustcacheparameter, true) page_request.send(null) } function loadpage(page_request, containerid){ if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1)) document.getElementById(containerid).innerHTML=pag e_request.responseText } function loadobjs(){ if (!document.getElementById) return for (i=0; i<arguments.length; i++){ var file=arguments var fileref="" if (loadedobjects.indexOf(file)==-1){ if (file.indexOf(".js")!=-1){ fileref=document.createElement('script') fileref.setAttribute("type","text/javascript"); fileref.setAttribute("src", file); } else if (file.indexOf(".css")!=-1){ fileref=document.createElement("link") fileref.setAttribute("rel", "stylesheet"); fileref.setAttribute("type", "text/css"); fileref.setAttribute("href", file); } } if (fileref!=""){ document.getElementsByTagName("head").item(0).appe ndChild(fileref) loadedobjects+=file+" " } } } </script> My question: Will this affect SEO adversely? As well, does using this script have any other negative effects? It basically loads separate internal content into a specified <div>, as opposed to loading the entire page - but - I've heard it can hurt in the search engine department. Any advice is greatly appreciated, thank you.
