Control what Google displays
When Google shows your website pages in it's Search Engine Result Pages (SERPs) it normally uses content from the page itself. The heading is taken from your pages title and the snippet is often taken from your pages meta description.
What if your page title or meta description is missing, poor or doesn't relate well to the search query? In these cases Google will find another source for the text to display. This maybe from page headings, visible content or even text in links pointing to the page (Link Text in Back Links).
Google will only display so much information. Around 70 characters for the heading and 2 lines for the snippet. This tool helps you see what your website may look like in Google Results, so you can fine tune it to look the most attractive to viewers.
If you want to test how an an existing page looks in Google's results, enter its URL then click Acquire Text.
You can then edit the title and description to see what it will look like in Google's Search Results. Click Generate to update the emulated results.
Google highlights words in the search results that match the words that were searched on. You can emulate this by adding words to the Search Word list. They should be space separated.
I have also written articles about how to write good Titles and Descriptions so that they work for search engines and attract visitors to your website. If you're interested in seeing how you rank is search results then also check out my Google Search Result Parser.
