There are several reasons why last spring's "Daylight Savings Time" post continue to increase Susanna Speier's blog traffic by more than 500%. She tells us the global monthly search volume for the grammatically incorrect keyword phrase, "Daylight Savings," brings in 1,000,000, while the correct keyword phrase, "Daylight Saving," brings in about 368,000, according to Google's AdWords Keyword Tool. Speier says you should choose words in both the headline and body copy carefully - which could mean "compromising" your "grammatical integrity" to appeal to a majority of the population.

Should business owners hire a digital marketing company that cold-called them looking for work? Absolutely not, says Miriam Ellis. "I've seen one too many small business owners get burned by $9.99 website builder companies and generic PPC management offers.... Genuine rapport and a personal investment will develop between provider and owner and I am convinced that the business owner is going to be far better off working with someone whose chief concern is client well-being rather than whether his boss will fire him tomorrow for not picking up enough new accounts."

Think of a sitemap as a note to search engine spiders, providing directions on the pages to crawl and index, says Stephanie Woods. Some people create a sitemap from scratch, while others use a XML site generator. Woods steps through the process of creating both XML and HTML sitemaps. A checklist helps to determine the creation path to take and whether to submit the sitemap to search engines. While some believe submitting a XML sitemap to search engines is a futile exercise, at least the site gets indexed, she writes.

When optimizing videos to rank high in search engine page results, treat the video like any other Web page and think about increasing the number of inbound links, says Shimon Sandler. He runs down 10 tips to optimize the clips so they serve up high in the SERPspoints, including a "great productivity tool that can make it easier to upload videos to multiple sharing sites."

Google Caffeine makes more sense to Dave Harry now that he has analyzed the potential of Google Social Search. Returning results in queries from people in your social circle and personalization will take processing power, he explains. Harry explains why social search has far greater implications than the recent news from Twitter and Google. He points to the SocialGraph API to understand how back-end technology can connect information and serve it up on the Web in real time. The connections create a "profile of your potential interests in contacts and content," he writes.

Patrick Winfield offers some tips on how to get the correct thumbnails to show on social sites -- problematic, especially when someone else has submitted your content. These "visual additions" to text links can make the difference in the topic being read or passed over for another. Winfield explains how to correct this problem in media RSS and MRSS feeds, Digg, Facebook, Reddit and StumbleUpon -- sometimes, by using an application called iTag, which allows you to embed titles, descriptions and keywords into your video or photos.

Jennifer Laycock notes one big problem for corporate Facebook pages: the social media site insists that one person, rather than a company, must register the page. Another problem: Facebook hides the "Create a page" link in several places on the chance you might stumble across one, Laycock writes. But she tells you where to look, how to get started and how to send status updates from a mobile phone. It's becoming more important for companies to have a Facebook page since search engines will feed social media updates into queries in real time.

On the advice of a reader, Peter Da Vanzo steps through the process of managing and demonstrating the value of a social media campaign. Some of the measurements he believes are important are rising revenue, the competitive advantage, increases in visitor numbers, and reach. While there's no one tool or technique that can measure and track all data, Da Vanzo suggests considering analytics, behavior tracking, dedicated tracking codes for links, coupon codes on Facebook or Twitter, and customer surveys. A satirical video Da Vanzo lifts from YouTube explains why marketers should consider social media.

For those who want to sort posts based on interests, Alex Chitu tells us that Google Reader has added a feature called "sort by magic" that can do just that. Sort by magic replaces Google Reader's auto sorting feature, which Chitu explains is no longer available. The new feature works by prioritizing subscriptions with fewer items, according to Chitu. The setting prevents friend's blogs from being drowned out by higher volume sites, such as the New York Times, he explains. He also explains another feature called "popular items."

Jen Lopez interviews Google's Maile Ohye. In the video, Ohye talks about the best approach for indexing deep sites, handling multiple sitemaps, influencing frequent crawls and schedules, duplicating content from scrapper sites and more. Ohye tackles Lopez's question on scheduling Google bots to crawl the site by discussing the importance of bandwidth. She explains that while a company can't specify the time of day for Google bots to crawl the site, a feature inside Google Webmaster Tools lets companies slow down the crawl rate.
