What's our easiest, quickest "win" for page load speed?
-
This is a follow up question to an earlier thread located here: http://www.seomoz.org/q/we-just-fixed-a-meta-refresh-unified-our-link-profile-and-now-our-rankings-are-going-crazy
In that thread, Dr. Pete Meyers said "You'd really be better off getting all that script into external files."
Our IT Director is willing to spend time working on this, but he believes it is a complicated process because each script must be evaluated to determine which ones are needed "pre" page load and which ones can be loaded "post."
Our IT Director went on to say that he believes the quickest "win" we could get would be to move our SSL javascript for our SSL icon (in our site footer) to an internal page, and just link to that page from an image of the icon in the footer. He says this javascript, more than any other, slows our page down.
My question is two parts:
1. How can I verify that this javascript is indeed, a major culprit of our page load speed?
2. Is it possible that it is slow because so many styles have been applied to the surrounding area? In other words, if I stripped out the "Secured by" text and all the syles associated with that, could that effect the efficiency of the script?
3. Are there any negatives to moving that javascript to an interior landing page, leaving the icon as an image in the footer and linking to the new page?
Any thoughts, suggestions, comments, etc. are greatly appreciated!

Thanks Stremline. Yes, it was clear from this report from Pingdom.com that our SSL validation icon was the biggest culprit bogging down our pagespeed. We are moving the JS to an interior page and then linking to that page via the .gif image icon to see if this helps.
After that, is seems our next biggest culprits could be images. Some of them are association images that could easily be combined into one optimized image.
The two "problem child" javscripts seem to be "iaf.js" and "CCI-utils.js" - Although I don't code javascript I believe these pertain to site functions like the popout navigation menus.
Awesome tool. Thank you. Do you have any developer tools that can help determine when javascripts load (pre versus post), etc. Thoughts?
Thanks again!

1. Here's a tool to show what takes the longest to load on your page - http://tools.pingdom.com/fpt/
Let me know if JavaScript is in fact the culprit here and I can provide some additional help.

Should I create a new site or keep company on parent company's subdomain?
I am working with a realty company that is hosted on a subdomain of the larger, parent realty company: [local realty company].[parent realty company].com How important is it to ride on the DA of the larger company (only about a 40)? I'm trying to weigh the value of creating an entirely separate domain for simplicity of the end user and Google bots: [local company].realtor They don't have any substantial links to their subdomain, so it wouldn't a huge loss. I have a couple options... Create an entirely new site on their current subdomain, leveraging the DA of the larger parent company. Create an entirely new site on a new URL, starting from scratch (which doesn't hurt you as much as it seems it once did). Create two sites, a micro site that targets a sector of their audience that they really want to reach, plus option (1) or (2). Love this community!

Do I submit a sitemap for a highly dynamic site or not? If so, what's the best way to go about doing it?
I do SEO for online boutique marketplace. I've been here for about 4 weeks and no one's done there SEO (they've been around for about 5 years), so there's lots to do. A big concern is whether or not to submit a sitemap, and if I do submit one, what's the best way to go about doing one.

Fowarding URL's Have No SEO Value?
Good Morning from -3 Degrees C no paths gritted wetherby UK 😞 Imagine this scenario. http://www.barrettsteel.com/ has been optimised for "Steel suppliers" & "Steel stockholders". After runnning an on page SEO moz report its recommended that the target terms should be placed in the url eg www.steel-suppliers.co.uk Now the organisation will not change the url but think setting up a forwarding url eg registering www.steel-suppliers.co.uk to then forward to www.steel-suppliers.co.uk will be of benfit from an SEO perspective. But i think not. So my question is please "is a forwarding url of no value but a permanent URL (struggling for the terminology to describe the url a site is set up with) such as www.steel-suppliers.co.uk would be of value?" Any insights welcome 🙂

Is having "rel=canonical" on the same page it is pointing to going to hurt search?
i like the rel=canonical tag and i've seen matt cutts posts on google about this tag. for the site i'm working on, it's a great workaround because we often have two identical or nearly identical versions of pages: 1 for patients, 1 for doctors. the problem is this: the way our content management system is set up, certain pages are linked up in a number of places and when we publish, two different versions of the page are created, but same content. because they are both being made from the same content templates, if i put in the rel=canonical tag, both pages get it. so, if i have: http://www.myhospital.com/patient-condition.asp and http://www.myhospital.com/professional-condition.asp and they are both produced from the same template, and have the same content, and i'm trying to point search at http://www.myhospital.com/patient-condition.asp, but that tag appears on both pages similarly, we have various forms and we like to know where people are coming from on the site to use those forms. to the bots, it looks like there's 600 versions of particular pages, so again, rel=canonical is great. however, because it's actually all the same page, just a link with a variable tacked on (http://www.myhospital.com/makeanappointment.asp?id=211) the rel=canonical tag will appear on "all" of them. any insight is most appreciated! thanks! brett

Mask links with JS that point to noindex'ed paged
Hi, in an effort to prepare our page for the Panda we dramatically reduced the number of pages that can be indexed (from 100k down to 4k). All the remaining pages are being equipped with unique and valuable content. We still have the other pages around, since they represent searches with filter combination which we deem are less interesting to the majority of users (hence they are not indexed). So I am wondering if we should mask links to these non-indexed pages with JS, such that Link-Juice doesn't get lost to those. Currently the targeted pages are non-index via "noindex, follow" - we might de-index them with robots.txt though, if the "site:" query doesn't show improvements. Thanks, Sebastian
