Web 2.0 Social Tagging Sites, Part 1: Alexa Rankings

Here are the rankings for 42 Web 2.0 social tagging sites, according to Alexa. Although Alexa is notorious for its lack of precision, as documented by GigaOM, SEO Book, BloggingStocks and others, it's still useful as a rough guide to website popularity. A site ranked at 20,000 may not really be more popular than the site at spot 25,000, but it certainly gets more traffic than a site ranked at 200,000. As pointed out at PaulStamatiou.com, "While you shouldn’t quote Alexa rankings as ultimate truth, Alexa data is useful for comparing website to website, especially when those websites are in the same market (ie: Digg.com vs. Reddit.com)."

Furthermore, as WebKEW, Robin Good and others have noted, "Alexa's rankings tend to be extremely accurate, especially for the top 10,000 sites." 15 of the sites listed here fall into that group. Robin Good actually places the number at as many as 50,000, which encompasses 29 of these Web 2.0 social tagging sites.

So, take these with a grain (or two) of salt, but here are the current rankings:

Social Bookmarking Sites in Top 10,000:

Yahoo! MyWeb

Getting More Out of Each Click with "Post-Click Marketing"

With the economy now officially in a recession (as if we didn't know that), marketers are under increasing pressure to do more with less. On the interactive marketing side, few marketers will get budget increases enabling them to drive more clicks. The challenge, then, is to maximize marketing productivity—to get more leads out of the same number of clicks. This is the first of two posts that will look at how to improve conversion rates to get more value from each click. One answer to this challenge is provided by "post-click marketing," a.k.a. lead automation management vendors. While the specifics of each service vary, all of them essentially: automate the process of extracting visitor IP information from your log files; match the IP address to an organization; filter out ISPs; and map the company name to one or more external databases to provide additional information (company size, industry, key contacts etc.). The better services also use geo-location filte...

Best of 2007: Articles and Blog Posts on SEM

Search engine marketing (SEM) is one of the fastest-growing categories in all of advertising, because it is both measurable and logical: present your ads when people are searching for what you're selling. A well-crafted search marketing program can provide not only broad brand exposure at a very reasonable cost (with CPMs of $10 or less), but also high-ROI lead generation. As with any other type of advertising, however, a poorly-designed campaign will be a disappointing waste of money. In addition to best practices in search engine marketing , the following articles and blog posts were among the best of 2007 at providing helpful guidance for creating and managing effective search marketing programs. Five Common Paid Search Mistakes That Can Sink Your Campaign by Search Engine Guide Blogger Jennifer Laycock explains how common mistakes such as "ego bidding," writing a single ad for all keywords, and directing all of your traffic to a single landing page can limit the res...

The 8 Layers of a B2B Web Marketing Plan

One way to think about designing a B2B technology web marketing plan is as a series of layers, like an onion. At the core is SEO—simply making your website "findable" through organic search to buyers who are looking for what you offer. Working out from the center are concentric layers of additional investment and sophistication. Small companies and start-ups with modest budgets will focus most of their efforts on the inner layers or rings, which are primarily designed for lead generation. As the company and its marketing budget grow, efforts can be expanded to the outer layers, which are aimed more at branding but support lead generation efforts. Ideally, a company eventually reaches the outer layer where pure branding activities (such as print advertising) help to maximize the effectiveness of lead generation programs (such as SEM) near the center of the circle. This diagram shows how different types of web marketing programs can be prioritized in order to maximize the retur...
