CSS background images weight impact
-
Hi,
do you think that the use of a single 1.8Mb background image sitewide could have a big negative impact and make a website disappear from SERPS?thank you

Hi Gianni,
There are a ton of reasons why your website might have slipped down the SERPs or dropped rankings. It's almost certainly not because of your image.
If you want, you can PM me your URL and I'll have a look.

Hello,
I think the heavy wheight background image has been wrongly pubilshed without the proper jpg compression during last months... (maybe a webdesigner distraction).Anyway now the website is disappeared from SERPS,
I'm trying to spot the possible reason of this penalization, currently the homepage ranks "A" with Seomoz on page optimization tool for the primary keyword, and it's domain metrics are equals or superior to many competitors that rank in first page for the same keyword.
With this heavy wheight background image the overall wheight of the internal pages is about 2.8 Mb (html/css + scripts + inline images + css background images ), I think this is a really uncommon and high value.
If Google considers a page as "loaded" when all of its assets were actually downloaded from the server and not when the event "load" fires on the browser I think it could be a very negative factor.
Thank you all for your replies
(and sorry for my english) -
That is a pretty large image file, I do not know how it would impact the SERPS.
If you are using photoshop and saving the background image as a Jpg, one thing I always try to do is lower the quality when saving for web to around 30-40 for really large images (can notice a difference but not too bad) or lower the quality to 51 if you want the image to remain pretty much the same.
Another thing that I like to do is use Smush.it (http://www.smushit.com/ysmush.it/) which is a free tool from Yahoo that will save you a little on filesize without changing the appearance of the image.
Hope this helps!

1.8mb is HUGE, what on earth is in there? I have a full background complex image for one of my websites - it's 90kb. Even the biggest CSS sprite image I have is just 30kb that includes most of my site template.
I recommend that you revisit this and use a different image format if not jpg/png/gif - for example never use tif or BMP online.
A background this size will really look poor to your first time visitors - this is exactly why Google want to start using speed as a ranking factor.

Just to add - try and compress the image as much as you can.
I'd be more worried about waiting for it to load and it having a knock on effect on your user experience.

Hi Gianni,
of course the huge image won't make the website disappear from the serps - if you define "disappear" that the website is banned from the index.
I suppose you know that speed / loading time already matters, but it is just one of many ranking factors and Matt Cutts said that very rare pages are concerned. But imagine that there is a website with exactely the same condition as yours then the one with less loading time will be "better" than yours.
Even though the image is in the css defined it is not the best idea. Did you really compress the image yet?

When Google rewrites a title tag, do you get the SEO impact for the original version?
Let's say you're writing a homepage title tag like this: KEYWORD | BRAND and Google rewrites it as BRAND | KEYWORD From Moz and best practices, we believe that keywords closer to the beginning of a title tag may have more impact on search rankings. So, when Google rewrites the title tag, do you get the impact you would have made with the keyword being closer to the front? Or, does Google give you the impact you would have received with the keyword being at the end?

Does css float affect SEO?
It is generally believed that the closer the content is to the top of the page, the better it is for SEO. If that's incorrect, please let me know. I have a 2 column site where the left menu is navigation and right side is content. Obviously, the left menu appears in the code before the content does, but I can flip them around via css float. If I do that, the content will appear on the left visually, even though in the code it still comes after the left side navigation. Do either positions affect seo?

My Images Aren't Indexed By Goolge
My site is indexed by google, and there hasn't really been much of a problem with my content, but now I am noticing that none of our images are coming up in the images searches of google. I mean none. I have even typed in the alt text of the image verbatim and nothing shows up. I use wordpress if this helps anyone. Any advice would be awesome, Thanks a lot.

Home page mostly graphic image
I have a new customer that is redesigning her website. The graphic designer has designed a lovely homepage that is mostly an image with some navigation and footer area for text information. My concern is that there isn't any real call to action or anything on the homepage design other than an interesting and fun graphic. It seems like years ago this was a common practice and then later it was looked down on as not good for the user experience or SEO. What is the latest thinking on this type of design? Should the homepage (www.mysite.com) be allowed to be mostly images? Or should we focus on the optimizing the internal pages and let the homepage be more creative?

Do Schema.org changes impact local SEO
I've reviewed the various presentation and blog posts from SMX advanced regarding local SEO and I didn't see any mention of Schema.org and microformats. Has any research or case studies been presented supporting that implementation of Schema.org microformats will improve local results? Here is one example where I've implemented the basics in the address info of the footer. http://bit.ly/lZQYeg Any tips on how to further optimize with schema.org markup?

Impact of removing category sidebar with keywords?
Our site (a niche financial publication: insideARM.com) requires some more room in the sidebar. We're considering removing the categories (we call them topics) sidebar block, or cutting down the number of items displayed within it. My concern is that we'd be removing a direct link to landing pages for important keyword terms from our most powerful page (the index). Sure, we have the terms listed in the footer, but I am worried that the position change will lower the value of the links. Our users don't really use these links for navigational purposes, which is why it comes up as a potential removed item. Am I wrong to worry about this? Would we be crippling our category pages by doing this?
