Fading in content above the fold on window load

[noyelling]

Hi,

We'd like to render a font stack from Typekit and paint a large cover image above the fold of our homepage after document completion. Since asynchronously loading anything generally looks choppy, we fade in the affected elements when it's done. Sure, it gives a much smoother feeling and fast load times, but I have a concern about SEO.

While Typekit loads, h1, h2 and the page's leading paragraph are sent down the wire with an invisible style (but still technically exist as static html). Even though they appear to a user only milliseconds later, I'm concerned that a search engine's initial request is met with a page whose best descriptive assets are marked as invisible.

Both UX and SEO have high value to our business model, so we're asking for some perspective to make the right kind of trade off. Our site has a high domain authority compared to our competition, and sales keyword competition is high. Will this UX improvement damage our On-Page SEO? If so and purely from an SEO perspective, roughly how serious will the impact be?

We're eager to hear any advice or comments on this. Thanks a lot.

Hi,

For starters you could use the ‘Fetch as Google’ option in Webmasters Tools and see what your page looks like to search engines, or use a tool like browseo.net to do the same thing. Or you could make sure the page is indexable and link to it from somewhere and do a search for “one of your hidden text strings” (in quotes) to see if that content has been crawled and indexed.

If you can’t see your content then you may have a problem, and as crawlers can distinguish between hidden and nothidden text it may be more than just blocking your content from helping you rank. It might actually look like you’re trying to stuff keywords into your content without showing them to the user.

I think the easiest and simplest fix would be to remove the class which makes these elements invisible, and dynamically add that class with a little bit of jQuery just for users with scripts enabled:

This way when a crawler (or a user with javascript disabled) visits your site they will be served the page with the content visible, with it only being hidden if the visitor is accessing the site with javascript enabled.

Hope this helps,

Tom
