To Bold or Not To Bold? That’s a Google Question.
Google has long highlighted search terms in the search results (SERPS) using bold text. As with all things Google, this practice is evolving not static and there are no hard and fast rules. Increasingly, Google is also highlighting abbreviations and acronyms not just the exact search terms. For example, a search on “ROI” returns results highlighting “Return on Investment” as well as “ROI” itself. Similarly, search on “PPC” and “Pay Per Click” will be highlighted.
Now there seems to be a shift towards highlighting words of semantic equivalence as well. Interestingly, a Google search on “Search Engine Marketing” performed on 5th July 2010 returned the following:
Notice that the direct acronym “SEM” isn’t highlighted by “SEO” is.
Bold text draws the searchers eye and grabs their attention. Highlighting doesn’t impact on search engine rankings but is likely to have some impact on click through from the SERPS to your website.
Climbing to the top of the search returns is a question of smart Search Engine Optimisation. But once you get there, your website needs to sell itself to encourage searchers to actually click through to your website. The challenge becomes one of Search Engine Marketing.
The preview text displayed with each web result is known as the snippet. Search engines often use the meta description as the snippet – hence the great importance of writing good meta descriptions. Clearly, a meta description must contain important keyphrases and accurately describe the content of the page, but a really good meta description must also capture the searcher’s interest like an advertisement so they click through to your website.
In retrospect, perhaps the title for this post should have been “To Click or Not to Click”. Online Marketers don’t have direct control over the snippets displayed for their webpages – neither over the text itself or which terms appear in bold. But, we can and we should monitor and experiment in the search for the best results.
