Heads up: we're pushing a new Panda data refresh that noticeably affects only ~1% of queries worldwide. More context: goo.gl/HNvCt
My hunch is that this update is not yet stable (for sure) and will more likely be upgraded to total devaluation of low quality/spam/unnatural links to somehow neutralize the growing fear of Negative SEO. Not allowing these links to pass any value will decrease the rankings of those who have benefitted from it in the past, and will also protect those who might get abused by unethical link attacks in the future (building crap links to competitors).
- Aggressive exact-match anchor text
- Overuse of exact-match domains
- Low-quality article marketing and blog spam
- Keyword stuffing in internal/outbound links
width
for container elements, we started using max-width
instead. In place of height
we used min-height
, so larger fonts or multi-line text don’t break the container’s boundaries. To prevent fixed width images “propping open” liquid columns, we apply the following CSS rule:img {
max-width: 100%;
}
device-width
in the region of 320px. If your mobile device actually has a width of 640 physical pixels, then a 320px wide image would be sized to the full width of the screen, using double the number of pixels in the process. This is also the reason why text looks so much crisper on the small screen – double the pixel density as compared to a standard desktop monitor. width
to device-width
in the viewport meta tag is that it updates when the user changes the orientation of their smartphone or tablet. Combining this with media queries allows you to tweak the layout as the user rotates their device:
@media screen and (min-width:480px) and (max-width:800px) {
/* Target landscape smartphones, portrait tablets, narrow desktops
*/
}
@media screen and (max-width:479px) {
/* Target portrait smartphones */
}
orientation
media query to target specific orientations without referencing pixel dimensions, where supported.
@media all and (orientation: landscape) {
/* Target device in landscape mode */
}
@media all and (orientation: portrait) {
/* Target device in portrait mode */
}
