Google just announced that it will be putting a notice next to any websites that it believes have been hacked. If your site has been subject to a malicious attack then in the search results, under the title, the phrase "This site may be compromised" will start to display.

In a post on their Webmaster blog, Google announced..."To protect the safety of our users, we show this warning message for search results that we believe may have been hacked or otherwise compromised. If a site has been hacked, it typically means that a third party has taken control of the site without the owner’s permission. Hackers may change the content of a page, add new links on a page, or add new pages to the site. The intent can include phishing (tricking users into sharing personal and credit card information) or spamming (violating search engine quality guidelines to rank pages more highly than they should rank)."

While Google has placed malware warnings in the search results before, the interesting development here is that even without malware, potential visitors could still be warned away from your site. The "violating search engine quality guidelines to rank pages more highly than they should rank" could have a serious impact on sites that have used black-hat techniques to get to the top of the search engines. Any site that Google deems to have broken the rules may not only receive a ranking penalty, pushing it far further down the results, but the stamp next to it warning users away may lead to a much larger drop in visitors.

In a clean-up of its services, Yahoo! is about to remove a number of “underperforming” websites, including a few very well known brands.

Those of us who have been involved in search engine marketing for years will remember when Altavista was the Google of its day. Anyone involved in social media marketing will undoubtedly have spent time on the bookmarking website, Delicious.

In addition to these two sites, AlltheWeb (another search site), Babelfish (a translation service), Buzz (a news aggregation site) and MyBlogLog (a social media network, similar to Facebook) are all also likely to be taken off the web.

For the sake of posterity, here’s a screenshot of Delicious:

 

A Yahoo! spokeswoman said “Part of our organizational streamlining involves cutting our investment in underperforming or off-strategy products to put better focus on our core strengths and fund new innovation in the next year and beyond...We continuously evaluate and prioritize our portfolio of products and services, and do plan to shut down some products in the coming months...We will communicate specific plans when appropriate."

The company is also planning on cutting its workforce by 4%, which equates to about 600 jobs.

If your website receives traffic or has links pointing to it from any of the Yahoo! properties that are going to disappear then put measures in place to limit the impact. Start taking advantage of other social media, bookmarking and blog sites ASAP, to strengthen your link profile and the number of referring sites.

Whether you are a fan of Google's new Instant search or not, if you are running a PPC campaign then this post will be of interest to you.

There appears to be a glitch in Instant search that could be costing top spot advertisers dearly. Whilst Instant search is turned on, if a search returns Adwords ads above the organic SERPs and you hit enter twice in the search field you will automatically open the number 1 Adwords result. This costs whoever is in the top spot, but the user won't have made the choice to click the ad, so what will they do? Click back, because they were expecting a Google search results screen.

This will have a detrimental effect on top position bounce rates and could be wasting a great deal of advertiser's budgets.
