Is it possible to pass text values into Marketo landing pages using URL parameters?

For clarification:  Do you want to pass URL parameter information into a Marketo page in order for "dynamic" content to be populated on the page for SEO purpose or are you just attempting to pass information into hidden form fields in order to pass that information to your Lead Database?

I plan to pass in text which would be used to alter existing text on the page via Adwords URL parameters.  I have learned yesterday that Marketo pages allow parameter parsing via simple Javascript.

Do you mean query strings? I haven't used marketo in a long time but I vaguely remember ability to do this... For other marketing automation tools not limited to Marketo I use query strings to pass values to do many interesting things from link IDs to field values. For example you could use a few lines of javascript to pull a query string value out of a URL and submit it as a form field upon submit. Query strings are incredibly powerful and allow for a lot of flexibility and creativity.

In Marketo, you need RTP (Real Time Personalization) to do this well. It’s an add-on product, and (obviously, for Marketo) expensive.Alternately, you could use segmentation, as seen here (from Marketo user Alok): https://nation.marketo.com/external-link.jspa?url=http%3A%2F%2Finfo2.filemaker.com%2FFileMaker_Platform_Trial_Request.html%3FLanguage%3DENhttps://nation.marketo.com/external-link.jspa?url=http%3A%2F%2Finfo2.filemaker.com%2FFileMaker_Platform_Trial_Request.html%3FLanguage%3DFR In the above URL's content is regionalize on the basic Language Parameter and it setup using the segment only, if you want can use the tokens also with the segments.As a final alternate, you could create or modify a page template to get the code in you need (from Marketo user Robb Barrett):In your header of your template, you'll want this:<script type="text/javascript">function getUrlVars() {var vars = {};var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi,function(m,key,value) {vars[key] = value;});return vars;}var map = getUrlVars()["map"];var region = getUrlVars()["region"];var cities= getUrlVars()["cities"];</script>Now, in your HTML, where you want the stuff to appear, put this in:Map:<img id="map-img"><script>var mapimg = map;document.getElementById("map-img").src = mapimg ;</script>Cities:<ul id="itemList"></ul><script>var itemsExist = true;var indexNum = 0;var unorderedList = document.getElementById('itemList');var str = cities;var res = str.split("%20%");var myElement;function write_cities() {for (i = 0; i < res.length; i++) {// Create the <LI> elementmyElement = document.createElement("li");// Add the letter between the <LI> tagsmyElement.appendChild(document.createTextNode(res[indexNum++]));// Append the <LI> to the bottom of the <UL> elementunorderedList.appendChild(myElement);}}if (itemsExist) {write_cities();}</script>Region:<p id="Region-Name"></p><script>var regionname = region ;document.getElementById("Region-Name").innerHTML = regionname;</script>
