Strange enough i've never looked for option 'Similar' but now i release that by my site only option 'Cached' is available and not 'Similar'. I think it is strange because my site seems to be almost only one in that niche where this option is not available.
Also when i look by another competitors sites in same niche for 'Similar' then i can see some good positions for my other site that lose long time a go key positions but for my main site that have a lot top 10 positions i do not see anything
Strange? Wonder why my main site does not have option 'Similar' and why it does not show up by looking by another website under 'Similar'?
