How easy is it for search engine to crawl your site?

URLs are like the bridges between your website and a search engine’s crawler: crawlers need to be able to find and cross those bridges in order to get to your site’s content. If your URLs are complicated or redundant, crawlers are going to spend time tracing and retracing their steps; if your URLs are organized and lead directly to distinct content, crawlers can spend their time accessing your content rather than crawling through empty pages, or crawling the same content over and over via different URLs.
Google also shares some best practice tips for ensuring your URLs are fully optimized to be crawled and indexed by the Google crawler.
There are a few things that Google recommends you follow when ensuring your URLs are set-up correctly, which will help the crawlers find and crawl your content faster. These include:
• Remove user-specific details from URLs.
URL parameters that don’t change the content of the page—like session IDs or sort order—can be removed from the URL and put into a cookie.
• Disallow actions Googlebot can’t perform.
Using your robots.txt file, you can disallow crawling of login pages, contact forms, shopping carts, and other pages whose sole functionality is something that a crawler can’t perform.
• One URL, one set of content

Her is a presentasjon made in Google docs and is an explanation on the subject.

Google will Change Ranking Algorithm

Google will make changes to its search ranking algorithm to combat the spate of links leading to malicious web pages appearing at the top of Google’s search results, according to an inside source.
Over the past few months, cybercriminals have been using blackhat SEO techniques to manipulate search rankings. When it first began, they were marginally successful at following Google Trends to find buzzy search queries and elevating a newly created targeted webpage.

But after a short period of time, these same gangs appear to have become disturbingly effective. Last week, when researching a news story, I found the top five results all led to fake scareware pages.

Obviously if Google fails to do something about this manipulation, users will lose trust and the good ole days of Google will be over fast. A Googler speaking on condition of anonymity told WebProNews a ranking change is pending that tackles spam of this kind. Once the change goes live, users shouldn’t see it “nearly as often.”
The freshness or buzzy nature of a query also aided in this pursuit, and cybercriminals merely have to follow Google Trends and Google News to know which keywords and phrases to target.

SEO is Becoming More Important In Long Terms

It's a small business owner's dream to be the first result in Google when someone types in a word like "shoes." The resulting traffic stats and sales numbers would be incredible. However, it seems that small businesses might do much better by optimizing for queries involving more than one word.

Cost and feasibility need to be considered, of course - it's a rare small business that can pay for a site capable of competing with those owned by big corporations. But there's more to the situation than that.
It's in the land of three-, four-, and five-word searches that more and more people are spending their time, and together, 45.4 percent of the searches Hitwise has tracked so far this year fall into these categories.

Focusing your search engine optimization efforts on longer queries is something to think about instead of straining to create interesting one-word product names, then. Heck, attain a high ranking now, and maybe you'll even have a hold on it when the Reeboks of the world branch out.

SEO Starter Guide from Google

Google is getting into the SEO consulting business. Well, not quite. But, Google is now formally offering an “SEO Starter Guide” with practical advice for webmasters about improving search engine visibility and increasing traffic to a web site.

It is a 22-page PDF announced today on the Webmaster Central blog. This is the same guide Google uses internally for its own sites (YouTube, etc.).
The guide is well written and geared toward webmasters and business owners who need a basic training in SEO. Topics covered include:
• Page Titles
• Description Meta Tag
• URL Structure
• Site Navigation
• Creating Quality Content
• Anchor Text
• Heading Tags (H1s, H2s, etc.)
• Image Optimization
• Robots.txt
• Rel=”nofollow”
• Website Promotion
• Webmaster Tools
• Analytics
• More Resources

How to use the rel=”nofollow” attribute on individual links. Many in the SEO industry have thought this attribute is a red flag, something that tells Google that a professional SEO has been tweaking the page, and not something that an average webmaster would even know about. That’s clearly not the case anymore; rel=”nofollow” is more mainstream now thanks to a full page of explanation in this SEO guide.
