The five simple actions here can all be done in a matter of minutes.
When you break them down to their most basic ideas, it comes down to removing psychological barriers and offering better reasons to sign up. Without it, the page has no purpose. And yet so many sites make the call to action nearly invisible. Make sure that your call to action is differentiated from the rest of your page. Use contrasting colors, a larger font, and prominent positioning for the best results.
Test your call to action, too. Some phrasing might work better than others, and one button color might work better than another. The only way to know this for sure is to test the possible combinations. The goal is to get someone to sign up, right. So make it as easy and as simple as possible for them to do so. The best signup forms include no more than the absolute bare-minimum required information.
If money is involved, then make sure you only ask for the minimum amount of information required by your credit card processor.
If you need a shipping address, make sure they can auto-fill that information from their billing address. The key here is to lower the barrier to entry as much as possible.
Every additional field is an opportunity to change their mind. Guarantees are going to vary based on what your visitors are signing up for. If money is involved, make sure you offer some kind of satisfaction guarantee. But the problem there is that people are more likely to make a split-second decision to cancel. Psychologically, going to a separate signup page is a barrier.There were glimpses of Palace being more organised against City but in the end they still got stuffed.
Roy will be looking to get this trio of games out the way before his work in keeping Palace safe can begin in earnest.

With City scoring goals left, right and centre United know they need another big win to keep pace. To be honest, no one inside the game was overly worried about that sort of stuff but it was in the media a lot and has now been put to bed.
Morata is the new guy on the block but he has hit the ground running, while Aguero has being doing it for years now in the Premier League.
Chelsea did the double over City last year and from my experience when that happens you are even more fired up to go back and do well. The Brighton result will have brought Newcastle back down to earth after they picked up a head of steam. The boffins at Sun Bets tell me there has never been a Premier League game end 0-0 between these sides too so expect goals.

NFL Week 1 Betting Preview: Chiefs vs. The Patriots enter the 2017 NL season as favorites to win their record-tying sixth Vince Lombardi Tropy at sportsbook.
The New England Patriots enter the 2017 NFL season as the prohibitive favorites to win their record-tying sixth Vince Lombardi Trophy at sportsbooks monitored by OddsShark.
However, the NFC has a few top Super Bowl contenders hoping to prevent them from a repeat, with the Seattle Seahawks and Green Bay Packers meeting in a monster Week 1 matchup that could ultimately determine who earns home-field advantage. The Patriots officially kick off the season on Thursday against the Kansas City Chiefs, who many thought could challenge them last season before they lost at home to the Pittsburgh Steelers in the Divisional Round of the playoffs.
This year, New England will have star quarterback Tom Brady from the start, although he will not have top target Julian Edelman to throw to after he suffered a season-ending knee injury in the preseason. Instead, Brady will break in new addition Brandin Cooks, as the Patriots have been bet up to 9-point home favorites over the Chiefs after opening at -7.
In addition, Kansas City will be without running back Spencer Ware due to a season-ending knee injury, and this could be the last year quarterback Alex Smith has to lead the offense with rookie Patrick Mahomes waiting in the wings. The Chiefs have lost the past six road meetings at New England, according to the OddsShark NFL Database, going 2-4 against the spread.
The Patriots covered eight in a row to wrap up last season, when they finished with a remarkable 16-3 mark ATS overall. In the NFC, a showdown at Lambeau Field between the top teams in the conference based on future odds might be even more exciting.
The Packers saw their Super Bowl run fall short in the NFC Championship Game a year ago, with quarterback Aaron Rodgers doing the best he could with limited offensive weapons and an injury-plagued defense. Green Bay is a 3-point home favorite in this spot versus Seattle and has won the past seven home meetings in the series, covering the spread in the last four.
The Seahawks have an outstanding record recently as an underdog though, going 19-6-1 ATS in their previous 26 under that scenario. They were the most impressive team in the preseason too, totaling the most points en route to a perfect 4-0 mark SU and ATS.
