The most common SEO mistakes you need to avoid

Flash even just some graphics on the site really slows the load time which is another SEO factor.

That's right Bogart is right, loading time is an important SEO factor.

I will add that many sites are still using urls with session ID which show a lack of seriousness in SEO.

Session IDs are a big duplicate content issue. Every time a session ID is added, a duplicate page is created (in the eyes of the search engine).

Hi,

I understand about flash. But does anyone have an idea about images? How much weight can a single post have and still be OK?

Loading time is actually not yet an SEO factor. It is a potential future SEO factor. Matt Cutts merely made a comment that they are considering that as a future factor some time in 2010, but it has not yet been implemented. It is not part of Caffeine, as some people believe.

Here is the interview. Load speed is a separate issue from Caffeine.

Nonetheless, loading and rendering time has always been a big factor with me. I hate waiting for bloated 1.5 meg WordPress home pages to load. If you want a site to load and render quickly, try to keep the total page weight (the combined size in bytes for all code, images and objects) down to less than 200,000 bytes. 300k should be considered to be a top limit. This very hard to do if the page uses a lot of images.

To easily determine the page weight and loading times, use the Web Page Analyzer at the following site. It details all of a page's components and estimates loading times.

I doubt that Google can ever effectively implement page loading times as an SEO simply based upon a time-to-load factor. There are too many variables that a site owner cannot control, such as Internet traffic, network bottlenecks at hosting companies, servers that are overloaded etc. However, total page weight can be easily added to a ranking algorithm. Excessive number of objects and poorly written bloated code significantly effect loading and rendering times.


Session IDs are a big problem for duplicate content if they are showing up in the indexed pages. A good shopping cart will detect spiders and not use session IDs when a spider is visiting.

I found so many websites that have very good traffic and ranking an use stole content from other websites.

I know that unique and quality content is important, but how some sites have success with duplicate content?

They do not have long term success with duplicate content. Google's duplicate content filters appear to run separately from their ranking algorithm. It can sometimes take a few months for duplicate content pages to get wacked by Google. However, there is a threshold where the site's pages start to get de-indexed, which means the pages are removed from Google's index. Search engines only tolerate a certain amount of duplicate content.

The best SEO advice anyone can give you is to avoid using content from other web sites. Autoblogs are never a good idea.

Loading time was a SEO factor long time ago. I don't know if Google includes this factor on the algorithm now or in the future, but it seems logical.
