Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 2 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.

https://www.zillowstatic.com/vstatic/457c2eb/static/js/wombo-seed-concat.js

https://www.zillowstatic.com/static-zsg/e09a3e7/static-zsg/zsg/zsg-opt.css
https://www.zillowstatic.com/s/?static.457c2eb=css…brand-links-footer.css
Avoid landing page redirects

Your page has 2 redirects. Redirects introduce additional delays before the page can be loaded.
Avoid landing page redirects for the following chain of redirected URLs.
http://zillow.com/
http://www.zillow.com/
https://www.zillow.com/
Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 59% of the final above-the-fold content could be rendered with the full HTML response.
Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
https://s.yimg.com/wi/ytc.js (expiration not specified)
https://tag.mtrcs.samba.tv/v3/tag/Zillow/Hompage/sambaTag.js (expiration not specified)
https://accounts.google.com/o/oauth2/iframerpc?act….googleusercontent.com (10 minutes)
https://www.googletagmanager.com/gtm.js?id=GTM-P6HT97 (15 minutes)
https://www.googletagservices.com/tag/js/gpt.js (15 minutes)
https://connect.facebook.net/en_US/all.js (20 minutes)
https://apis.google.com/js/client:platform.js (30 minutes)
https://apis.google.com/js/rpc:shindig_random.js?onload=init (30 minutes)
https://bat.bing.com/bat.js (30 minutes)
https://www.google-analytics.com/analytics.js (2 hours)
Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 25.1KiB (62% reduction).
Compressing https://sync.graph.bluecava.com/js/bc.js could save 24.5KiB (62% reduction).
Compressing https://pixel.mtrcs.samba.tv/v2/tag/Zillow/Hompage…52F%3F&c=1494248850380 could save 526B (74% reduction).
Reduce server response time
